Mark A. Greer f13ab86a61 crypto: omap-sham - Only release DMA channel if successfully requested
In omap_sham_probe() and omap_sham_remove(), 'dd->dma_lch'
is released without checking to see if it was successfully
requested or not.  This is a bug and was identified and
reported by Dan Carpenter here:

	http://www.spinics.net/lists/devicetree/msg11023.html

Add code to only release 'dd->dma_lch' when its not NULL
(that is, when it was successfully requested).

Linus Torvalds 8ceafbfa91 Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
 "This series cleans up the handling of DMA masks in a lot of drivers,
  fixing some bugs as we go.

  Some of the more serious errors include:
   - drivers which only set their coherent DMA mask if the attempt to
     set the streaming mask fails.
   - drivers which test for a NULL dma mask pointer, and then set the
     dma mask pointer to a location in their module .data section -
     which will cause problems if the module is reloaded.

  To counter these, I have introduced two helper functions:
   - dma_set_mask_and_coherent() takes care of setting both the
     streaming and coherent masks at the same time, with the correct
     error handling as specified by the API.
   - dma_coerce_mask_and_coherent() which resolves the problem of
     drivers forcefully setting DMA masks.  This is more a marker for
     future work to further clean these locations up - the code which
     creates the devices really should be initialising these, but to fix
     that in one go along with this change could potentially be very
     disruptive.

  The last thing this series does is prise away some of Linux's addition
  to "DMA addresses are physical addresses and RAM always starts at
  zero".  We have ARM LPAE systems where all system memory is above 4GB
  physical, hence having DMA masks interpreted by (eg) the block layers
  as describing physical addresses in the range 0..DMAMASK fails on
  these platforms.  Santosh Shilimkar addresses this in this series; the
  patches were copied to the appropriate people multiple times but were
  ignored.

  Fixing this also gets rid of some ARM weirdness in the setup of the
  max*pfn variables, and brings ARM into line with every other Linux
  architecture as far as those go"

        - Creates platform devices for Job Rings.
(Earlier the initialization of Job ring  was done

Alex Porosanu 84cf48278b crypto: caam - fix RNG4 instantiation
The RNG4 block in CAAM needs to be 'seeded' first before being used
for generating pseudo-random data. The 'seeding' is done by getting
entropy from the TRNG ring oscillator. The RTFRQMAX register controls
the maximum allowable number of samples that can be aquired during
an entropy sample. Depending on the clock at which the RNG4 block
(and for that matter the SEC block) runs, it's possible that a
hard-coded value for the maximum frequency is inadequate, i.e. more
samples than needed are taken. This is an error, and thus the RNG4
block doesn't get initialized.  The patch attempts to alleviate
this issue by trying with progressivly larger frequencies, until
the number of samples is adequate.
This patch also fixes how a descriptor is deemed as being finished:
instead of checking the VALID field in the DECO debug register,
it makes sure that the DECO is idle, by checking the DECO state field
of the said register.

The way the DECO runs a descriptor through the direct (debug)

to locking up of the DECO. This patch adds a halt command at the
end of the descriptor to ensure the DECO halts when it reaches
the end of the descriptor buffer.

The way I read the Tegra AES RNG is that it has a homebrew

wheel, instead just grab 128bits from the kernel entropy pool
where the time and (after another patch) chip unique ID is
already mixed in.

Incidentally this also gets rid of a rather ugly
cross-dependence on the machine using an extern declaration.

Marcelo Cerri dec0ed6c1b crypto: nx - fix GCM for zero length messages
The NX CGM implementation doesn't support zero length messages and the
current implementation has two flaws:

 - When the input data length is zero, it ignores the associated data.
 - Even when both lengths are zero, it uses the Crypto API to encrypt a
   zeroed block using ctr(aes) and because of this it allocates a new
   transformation and sets the key for this new tfm. Both operations are
   intended to be used only in user context, while the cryptographic
   operations can be called in both user and softirq contexts.

This patch replaces the nested Crypto API use and adds two special
cases:

 - When input data and associated data lengths are zero: it uses NX ECB
   mode to emulate the encryption of a zeroed block using ctr(aes).
 - When input data is zero and associated data is available: it uses NX
   GMAC mode to calculate the associated data MAC.

For writing input buffer into DATA_IN register current driver
has the following state machine:

-> else use dma transfer.

In cases where requesting for DMA channels fails for some reason,
or channel numbers are not provided in DT or platform data, probe
also fails. Instead of returning from driver use cpu polling mode.
In this mode processor polls on INPUT_READY bit and writes data into
data_in regs when it equals 1. This operation is repeated until the
length of message.

Now the state machine looks like:
-> if input buffer < 9 : use fallback driver
-> else if input buffer < block size : Copy input buffer into data_in regs
-> else if dma enabled: use dma transfer
	   else use cpu polling mode.

Joel Fernandes 1bf95cca8f crypto: omap-aes - PIO mode: Add IRQ handler and walk SGs
We add an IRQ handler that implements a state-machine for PIO-mode and data
structures for walking the scatter-gather list. The IRQ handler is called in
succession both when data is available to read or next data can be sent for
processing. This process continues till the entire in/out SG lists have been
walked. Once the SG-list has been completely walked, the IRQ handler schedules
the done_task tasklet.

Also add a useful macro that is used through out the IRQ code for a common
pattern of calculating how much an SG list has been walked.  This improves code
readability and avoids checkpatch errors.

Joel Fernandes 4b645c9465 crypto: omap-aes - Simplify DMA usage by using direct SGs
In early version of this driver, assumptions were made such as DMA layer
requires contiguous buffers etc. Due to this, new buffers were allocated,
mapped and used for DMA. These assumptions are no longer true and DMAEngine
scatter-gather DMA doesn't have such requirements. We simply the DMA operations
by directly using the scatter-gather buffers provided by the crypto layer
instead of creating our own.

Lot of logic that handled DMA'ing only X number of bytes of the total, or as
much as fitted into a 3rd party buffer is removed and is no longer required.

Also, good performance improvement of atleast ~20% seen with encrypting a
buffer size of 8K (1800 ops/sec vs 1400 ops/sec).  Improvement will be higher
for much larger blocks though such benchmarking is left as an exercise for the
reader.  Also DMA usage is much more simplified and coherent with rest of the
code.

The co-processor has several limits regarding the length of
scatter/gather lists and the total number of bytes in it. These limits
are available in the device tree, as following:

 - "ibm,max-sg-len": maximum number of bytes of each scatter/gather
   list.

 - "ibm,max-sync-cop": used for synchronous operations, it is an array
   of structures that contains information regarding the limits that
   must be considered for each mode and operation. The most important
   limits in it are:
   	- The total number of bytes that a scatter/gather list can hold.
	- The maximum number of elements that a scatter/gather list can
	  have.

This patch updates the NX driver to perform several hyper calls if
needed in order to always respect the length limits for scatter/gather
lists.

Linus Torvalds 0bf6a210a4 ARM SoC driver specific changes
These changes are all driver specific and cross over between arm-soc
 contents and some other subsystem, in these cases cpufreq, crypto,
 dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
 have these changes merged through arm-soc. As we proceed to untangle
 the dependencies between platform code and driver code, the amount of
 changes in this category is fortunately shrinking, for 3.11 we have
 16 branches here and 101 non-merge changesets, the majority of which
 are for the stedma40 dma engine driver used in the ux500 platform.
 Cleaning up that code touches multiple subsystems, but gets rid
 of the dependency in the end.
 
 The mailbox code moved out from mach-omap2 to drivers/mailbox
 is an intermediate step and is still omap specific at the moment.
 Patches exist to generalize the subsystem and add other drivers
 with the same API, but those did not make it for 3.11.
 
 Conflicts:
 * In cpu-db8500.c results from the removal of the u8500_of_init_devices
   function in combination with the split of u8500_auxdata_lookup.
 
 * In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
   we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver specific changes from Arnd Bergmann:
 "These changes are all driver specific and cross over between arm-soc
  contents and some other subsystem, in these cases cpufreq, crypto,
  dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
  these changes merged through arm-soc.

  As we proceed to untangle the dependencies between platform code and
  driver code, the amount of changes in this category is fortunately
  shrinking, for 3.11 we have 16 branches here and 101 non-merge
  changesets, the majority of which are for the stedma40 dma engine
  driver used in the ux500 platform.  Cleaning up that code touches
  multiple subsystems, but gets rid of the dependency in the end.

  The mailbox code moved out from mach-omap2 to drivers/mailbox is an
  intermediate step and is still omap specific at the moment.  Patches
  exist to generalize the subsystem and add other drivers with the same
  API, but those did not make it for 3.11."

Joel A Fernandes a3485e685f crypto: omap-aes - Don't idle/start AES device between Encrypt operations
Calling runtime PM API for every block causes serious perf hit to
crypto operations that are done on a long buffer.
As crypto is performed on a page boundary, encrypting large buffers can
cause a series of crypto operations divided by page. The runtime PM API
is also called those many times.

We call runtime_pm_get_sync only at beginning on the session (cra_init)
and runtime_pm_put at the end. This result in upto a 50% speedup as below.
This doesn't make the driver to keep the system awake as runtime get/put
is only called during a crypto session which completes usually quickly.

Tobias Rauter 519d8b1a9d crypto: dcp - Added support for Freescale's DCP co-processor
This patch enables the DCP crypto functionality on imx28.
Currently, only aes-128-cbc is supported.
Moreover, the dcpboot misc-device, which is used by Freescale's
SDK tools and uses a non-software-readable OTP-key, is added.

Changes of v2:
- ring buffer for hardware-descriptors
- use of ablkcipher walk
- OTP key encryption/decryption via misc-device
  (compatible to Freescale-SDK)
- overall cleanup

The DCP is also capable of sha1/sha256 but I won't be able to add
that anytime soon.
Tested with built-in runtime-self-test, tcrypt and openssl via
cryptodev 1.6 on imx28-evk and a custom built imx28-board.

Kent Yoder 1ad936e850 drivers/crypto/nx: Fixes for multiple races and issues
Fixes a race on driver init with registering algorithms where the
driver status flag wasn't being set before self testing started.

  Added the cra_alignmask field for CBC and ECB modes.

  Fixed a bug in GCM where AES block size was being used instead of
authsize.

  Removed use of blkcipher_walk routines for scatterlist processing.
Corner cases in the code prevent us from processing an entire
scatterlist at a time and walking the buffers in block sized chunks
turns out to be unecessary anyway.

  Fixed off-by-one error in saving off extra data in the sha code.

  Fixed accounting error for number of bytes processed in the sha code.

Ruchika Gupta 986dfbcf8b crypto: caam - FIX RNG init for RNG greater than equal to 4
For SEC including a RNG block version >= 4, special initialization
must occur before any descriptor that uses RNG block can be
submitted. This initialization is required not only for SEC
with version greater than 5.0, but for SEC with RNG version >=4.
There may be a case where RNG has already been instantiated by
u-boot or boot ROM code.In such SoCs, if RNG is initialized again
SEC would returns "Instantiation error". Hence, the initialization
status of RNG4 should be also checked before doing RNG init.

Linus Torvalds 99c6bcf46d ARM: arm-soc multiplatform updates for 3.10
More multiplatform enablement for ARM platforms. The ones converted in
 this branch are:
 - bcm2835
 - cns3xxx
 - sirf
 - nomadik
 - msx
 - spear
 - tegra
 - ux500
 
 We're getting close to having most of them converted!
 
 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

  a patch in this branch to a early version of multiplatform conversion,
  but it ended up being reverted due to need of more bake time.  The

Vakul Garg 3862de1f6c crypto: caam - fix job ring cleanup code
The job ring init function creates a platform device for each job ring.
While the job ring is shutdown, e.g. while caam module removal, its
platform device was not being removed. This leads to failure while
reinsertion and then removal of caam module second time.

The following kernel crash dump appears when caam module is reinserted
and then removed again. This patch fixes it.

Vakul Garg 575c1bd549 crypto: caam - set RDB bit in security configuration register
This change is required for post SEC-5.0 devices which have RNG4.
Setting RDB in security configuration register allows CAAM to use the
"Random Data Buffer" to be filled by a single request. The Random Data
Buffer is large enough for ten packets to get their IVs from a single
request. If the Random Data Buffer is not enabled, then each IV causes a
separate request, and RNG4 hardware cannot keep up resulting in lower
IPSEC throughput if random IVs are used.

The Kconfig entry for CAAM's hash algorithm implementations has always
selected CRYPTO_AHASH. But there's no corresponding Kconfig symbol.

It seems it was intended to select CRYPTO_HASH, like other crypto
drivers do. That would apparently (indirectly) select CRYPTO_HASH2,
which would enable the ahash functionality this driver uses.

pm_runtime_put thus fixing a kernel panic observed on AM33xx SoC during
AES operation.

OMAP3 supports CTR while OMAP2 doesn't.  OMAP4/AM33XX
uses a different register set from OMAP2/OMAP3 and
also supports CTR.

To add this support, use the platform_data introduced
in an ealier commit to hold the list of algorithms
supported by the current module.  The probe routine
will use that list to register the correct algorithms.

Note: The code being integrated is from the TI AM33xx SDK
and was written by Greg Turner <gkmturner@gmail.com> and
Herman Schuurman (current email unknown) while at TI.

The data referenced by an interrupt handler should not be freed before the
interrupt is ended.  The handler is bfin_crypto_crc_handler.  It may refer
to crc->regs, which is released by the iounmap.

Furthermore, the second argument to all calls to free_irq is incorrect.  It
should be the same as the last argument of request_irq, which is crc,
rather than crc->dev.

The semantic match that finds the first problem is as follows:

Tony Lindgren a62a6e98c3 ARM: OMAP2+: Disable code that currently does not work with multiplaform
We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.

The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:

1. Some drivers are using custom omap_dm_timer calls

There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.

2. Hardware OMAP4_ERRATA_I688 needs to be fixed up

This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.

3. Legacy header needed for omap-sham.c

Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.

4. Mailbox is waiting to get moved to drivers

Disable it for now to avoid adding a dependency to the
mailbox patches.

Pull ARM SoC multiplatform conversion patches from Olof Johansson:
 "Here are more patches in the progression towards multiplatform, sparse
  irq conversions in particular.

  Tegra has a handful of cleanups and general groundwork, but is not
  quite there yet on full enablement.

  Platforms that are enabled through this branch are VT8500 and Zynq.
  Note that i.MX was converted in one of the earlier cleanup branches as
  well (before we started a separate topic for multiplatform).  And both
  new platforms for this merge window, sunxi and bcm, were merged with
  multiplatform support enabled."

Fix up conflicts mostly as per Olof.

Tony Lindgren 45c3eb7d3a ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.

Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.

So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.

The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.

Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.

Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.

Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.

Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

Nathan Fontenot 1cf3d8b3d2 powerpc+of: Add of node/property notification chain for adds and removes
This patch moves the notification chain for updates to the device tree
from the powerpc/pseries code to the base OF code. This makes this
functionality available to all architectures.

Additionally the notification chain is updated to allow notifications
for property add/remove/update. To make this work a pointer to a new
struct (of_prop_reconfig) is passed to the routines in the notification chain.
The of_prop_reconfig property contains a pointer to the node containing the
property and a pointer to the property itself. In the case of property
updates, the property pointer refers to the new property.

Sachin Kamat a465348ff5 crypto: s5p-sss - Fix compilation error
struct s3c2410_dma_client gets defined multiple times as it is defined
in more than one header file. Changing it at the header file level causes
many more build breakages as they are interdependent in a complex way.
Hence fixing this problem by using the mach version of the header file.

Without this patch, following build error is observed:

Tony Lindgren 27615a97b2 ARM: OMAP: Trivial driver changes to remove include plat/cpu.h
Drivers should not use cpu_is_omap or cpu_class_is_omap macros,
they should be private to the platform init code. And we'll be
removing plat/cpu.h and only have a private soc.h for the
arch/arm/*omap* code.

This patch is intended as preparation for the core omap changes
and removes the need to include plat/cpu.h from several drivers.
This is needed for the ARM common zImage support.

These changes are OK to do because:

- omap-rng.c does not need plat/cpu.h

- omap-aes.c and omap-sham.c get the proper platform_data
  passed to them so they don't need extra checks in the driver

- omap-dma.c and omap-pcm.c can test the arch locally as
  omap1 and omap2 cannot be compiled together because of
  conflicting compiler flags

Linus Torvalds 5e090ed7af ARM: soc: late platform updates
This branch contains updates to OMAP and Marvell platforms (kirkwood,
 dove, mvebu) that came in after we had done the big multiplatform merges,
 so they were kept separate from the rest, and not separated into the
 traditional topics of cleanup/driver/platform features.
 
 For OMAP, the updates are:
 - Runtime PM conversions for the GPMC and RNG IP blocks
 - Preparation patches for the OMAP common clock framework conversion
 - clkdev alias additions required by other drivers
 - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
 - OMAP hwmod code and data improvements
 - Preparation patches for the IOMMU runtime PM conversion
 - Preparation patches for OMAP4 full-chip retention support
 
 For Kirkwood/Dove/mvebu:
 
 - New driver for "address decoder controller" for mvebu, which
   is a piece of hardware that configures addressable devices and
   peripherals. First user is the boot rom aperture on armada XP since
   it is needed for SMP support.
 - New device tree bindings for peripherals such as gpio-fan, iconnect
   nand, mv_cesa and the above address decoder controller.
 - Some defconfig updates, mostly to enable new DT boards and a few drivers.
 - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
 - New clean gpio driver for mvebu

Horia Geanta 60542505b0 crypto: talitos - fix icv management on outbound direction
For IPsec encryption, in the case when:
-the input buffer is fragmented (edesc->src_nents > 0)
-the output buffer is not fragmented (edesc->dst_nents = 0)
the ICV is not output in the link table, but after the encrypted payload.

Copying the ICV must be avoided in this case; consequently the condition
edesc->dma_len > 0 must be more specific, i.e. must depend on the type
of the output buffer - fragmented or not.

Testing was performed by modifying testmgr to support src != dst,
since currently native kernel IPsec does in-place encryption
(src == dst).

Kim Phillips ce026cb9cb crypto: caam - fix possible deadlock condition
commit "crypto: caam - use non-irq versions of spinlocks for job rings"
made two bad assumptions:

(a) The caam_jr_enqueue lock isn't used in softirq context.
Not true: jr_enqueue can be interrupted by an incoming net
interrupt and the received packet may be sent for encryption,
via caam_jr_enqueue in softirq context, thereby inducing a
deadlock.

This is evidenced when running netperf over an IPSec tunnel
between two P4080's, with spinlock debugging turned on:

(b) since the caam_jr_dequeue lock is only used in bh context,
then semantically it should use _bh spin_lock types.  spin_lock_bh
semantics are to disable back-halves, and used when a lock is shared
between softirq (bh) context and process and/or h/w IRQ context.
Since the lock is only used within softirq context, and this tasklet
is atomic, there is no need to do the additional work to disable
back halves.

This patch adds back-half disabling protection to caam_jr_enqueue
spin_locks to fix (a), and drops it from caam_jr_dequeue to fix (b).

Seth Jennings 0e16aafb12 powerpc/crypto: add 842 hardware compression driver
This patch adds the driver for interacting with the 842
compression accelerator on IBM Power7+ systems.

The device is a child of the Platform Facilities Option (PFO)
and shows up as a child of the IBM VIO bus.

The compression/decompression API takes the same arguments
as existing compression methods like lzo and deflate.  The 842
hardware operates on 4K hardware pages and the driver breaks up
input on 4K boundaries to submit it to the hardware accelerator.

Kim Phillips 61bb86bba1 crypto: caam - set descriptor sharing type to SERIAL
SHARE_WAIT, whilst more optimal for association-less crypto,
has the ability to start thrashing the CCB descriptor/key
caches, given high levels of traffic across multiple security
associations (and thus keys).

Switch to using the SERIAL sharing type, which prefers
the last used CCB for the SA.  On a 2-DECO platform
such as the P3041, this can improve performance by
about 3.7%.

Shengzhou Liu 95bcaa3905 crypto: caam - add backward compatible string sec4.0
In some device trees of previous version, there were string "fsl,sec4.0".
To be backward compatible with device trees, we first check "fsl,sec-v4.0",
if it fails, then check for "fsl,sec4.0".

Kim Phillips 4a90507713 crypto: caam - fix possible deadlock condition
commit "crypto: caam - use non-irq versions of spinlocks for job rings"
made two bad assumptions:

(a) The caam_jr_enqueue lock isn't used in softirq context.
Not true: jr_enqueue can be interrupted by an incoming net
interrupt and the received packet may be sent for encryption,
via caam_jr_enqueue in softirq context, thereby inducing a
deadlock.

This is evidenced when running netperf over an IPSec tunnel
between two P4080's, with spinlock debugging turned on:

(b) since the caam_jr_dequeue lock is only used in bh context,
then semantically it should use _bh spin_lock types.  spin_lock_bh
semantics are to disable back-halves, and used when a lock is shared
between softirq (bh) context and process and/or h/w IRQ context.
Since the lock is only used within softirq context, and this tasklet
is atomic, there is no need to do the additional work to disable
back halves.

This patch adds back-half disabling protection to caam_jr_enqueue
spin_locks to fix (a), and drops it from caam_jr_dequeue to fix (b).

Jussi Kivilinna e15aa3692d crypto: drivers - remove cra_list initialization
Initialization of cra_list is currently mixed, most ciphers initialize this
field and most shashes do not. Initialization however is not needed at all
since cra_list is initialized/overwritten in __crypto_register_alg() with
list_add(). Therefore perform cleanup to remove all unneeded initializations
of this field in 'crypto/drivers/'.

Theodore Ts'o 9751bfd1c9 n2_crypto: remove IRQF_SAMPLE_RANDOM which is now a no-op
With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b.  The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.

Bharat Bhushan 1af8ea862c crypto: caam - Using alloc_coherent for caam job rings
The caam job rings (input/output job ring) are allocated using
dma_map_single(). These job rings can be visualized as the ring
buffers in which the jobs are en-queued/de-queued. The s/w enqueues
the jobs in input job ring which h/w dequeues and after processing
it copies the jobs in output job ring. Software then de-queues the
job from output ring. Using dma_map/unmap_single() is not preferred
way to allocate memory for this type of requirements because this
adds un-necessary complexity.

Example, if bounce buffer (SWIOTLB) will get used then to make any
change visible in this memory to other processing unit requires
dmap_unmap_single() or dma_sync_single_for_cpu/device(). The
dma_unmap_single() can not be used as this will free the bounce
buffer, this will require changing the job rings on running system
and I seriously doubt that it will be not possible or very complex
to implement. Also using dma_sync_single_for_cpu/device() will also
add unnecessary complexity.

The simple and preferred way is using dma_alloc_coherent() for these
type of memory requirements.

This resolves the Linux boot crash issue when "swiotlb=force" is set
in bootargs on systems which have memory more than 4G.

Kim Phillips a0ca6ca022 crypto: caam - one tasklet per job ring
there is no noticeable benefit for multiple cores to process one
job ring's output ring: in fact, we can benefit from cache effects
of having the back-half stay on the core that receives a particular
ring's interrupts, and further relax general contention and the
locking involved with reading outring_used, since tasklets run
atomically.

Memory barriers are implied by the i/o register write implementation
(at least on Power).  So we can remove the redundant wmb() in
caam_jr_enqueue, and, in dequeue(), hoist the h/w done notification
write up to before we need to increment the head of the ring, and
save an smp_mb.

Kim Phillips 1a076689cd crypto: caam - disable IRQ coalescing by default
It has been observed that in zero-loss benchmarks, when a
slow traffic rate is being tested, the IRQ timer coalescing
parameter was set too high, and the ethernet controller
would start dropping packets because the job ring back half
wouldn't be executed in time before the ethernet controller
would fill its buffers, thereby significantly reducing the
zero-loss performance figures.

Empirical testing has shown that the best zero-loss performance
is achieved when IRQ coalescing is set to minimum values and/or
turned off, since apparently the job ring driver already implements
an adequately-performing general-purpose IRQ mitigation strategy
in software.

Whilst we could go with minimal count (2-8) and timing settings
(192-256), we prefer just turning h/w coalescing altogether off
to minimize setkey latency (due to split key generation), and
for consistent cross-SoC performance (the SEC vs. core clock
ratio changes).
