When the source and destination register are identical, our JIT does not
generate correct code, which leads to kernel oopses.
Fix this by (a) generating more efficient code, and (b) making use of
the temporary earlier if we will overwrite the address register.

When an eBPF program tail-calls another eBPF program, it enters it after
the prologue to avoid having complex stack manipulations. This can lead
to kernel oopses, and similar.
Resolve this by always using a fixed stack layout, a CPU register frame
pointer, and using this when reloading registers before returning.

We expect to have firmware-first handling of RAS SErrors, with errors
notified via an APEI method. For systems without firmware-first, add
some minimal handling to KVM.
There are two ways KVM can take an SError due to a guest, either may be a
RAS error: we exit the guest due to an SError routed to EL2 by HCR_EL2.AMO,
or we take an SError from EL2 when we unmask PSTATE.A from __guest_exit.
For SError that interrupt a guest and are routed to EL2 the existing
behaviour is to inject an impdef SError into the guest.
Add code to handle RAS SError based on the ESR. For uncontained and
uncategorized errors arm64_is_fatal_ras_serror() will panic(), these
errors compromise the host too. All other error types are contained:
For the fatal errors the vCPU can't make progress, so we inject a virtual
SError. We ignore contained errors where we can make progress as if
we're lucky, we may not hit them again.
If only some of the CPUs support RAS the guest will see the cpufeature
sanitised version of the id registers, but we may still take RAS SError
on this CPU. Move the SError handling out of handle_exit() into a new
handler that runs before we can be preempted. This allows us to use
this_cpu_has_cap(), via arm64_is_ras_serror().

Non-VHE systems take an exception to EL2 in order to world-switch into the
guest. When returning from the guest KVM implicitly restores the DAIF
flags when it returns to the kernel at EL1.
With VHE none of this exception-level jumping happens, so KVMs
world-switch code is exposed to the host kernel's DAIF values, and KVM
spills the guest-exit DAIF values back into the host kernel.
On entry to a guest we have Debug and SError exceptions unmasked, KVM
has switched VBAR but isn't prepared to handle these. On guest exit
Debug exceptions are left disabled once we return to the host and will
stay this way until we enter user space.
Add a helper to mask/unmask DAIF around VHE guests. The unmask can only
happen after the hosts VBAR value has been synchronised by the isb in
__vhe_hyp_call (via kvm_call_hyp()). Masking could be as late as
setting KVMs VBAR value, but is kept here for symmetry.

On dra7, as per TRM, the HW shutdown (TSHUT) temperature is hardcoded
to 123C and cannot be modified by SW. This means that when the temperature
reaches 123C HW asserts TSHUT output which signals a warm reset.
The reset is held until the temperature goes below the TSHUT low (105C).
While in SW, the thermal driver continuously monitors current temperature
and takes decisions based on whether it reached an alert or a critical point.
The intention of setting a SW critical point is to prevent force reset by HW
and instead do an orderly_poweroff(). But if the SW critical temperature is
greater than or equal to that of HW then it defeats the purpose. To address
this and let SW take action before HW does keep the SW critical temperature
less than HW TSHUT value.
The value for SW critical temperature was chosen as 120C just to ensure
we give SW sometime before HW catches up.

Note that we had few mistakes that did not get noticed as we're still

So let's fix the omap4 and dra7 smartreflex registers as there is no

And on omap4, the mcasp module has a revision register according to

Setting si_code to 0 results in a userspace seeing an si_code of 0.
This is the same si_code as SI_USER. Posix and common sense requires
that SI_USER not be a signal specific si_code. As such this use of 0
for the si_code is a pretty horribly broken ABI.
Further use of si_code == 0 guaranteed that copy_siginfo_to_user saw a
value of __SI_KILL and now sees a value of SIL_KILL with the result
that uid and pid fields are copied and which might copying the si_addr
field by accident but certainly not by design. Making this a very
flakey implementation.
Utilizing FPE_FIXME, siginfo_layout will now return SIL_FAULT and the
appropriate fields will be reliably copied.
Possible ABI fixes includee:
- Send the signal without siginfo
- Don't generate a signal
- Possibly assign and use an appropriate si_code
- Don't handle cases which can't happen

We need to consistently enforce that keyed hashes cannot be used without
setting the key. To do this we need a reliable way to determine whether
a given hash algorithm is keyed or not. AF_ALG currently does this by
checking for the presence of a ->setkey() method. However, this is
actually slightly broken because the CRC-32 algorithms implement
->setkey() but can also be used without a key. (The CRC-32 "key" is not
actually a cryptographic key but rather represents the initial state.
If not overridden, then a default initial state is used.)
Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which
indicates that the algorithm has a ->setkey() method, but it is not
required to be called. Then set it on all the CRC-32 algorithms.
The same also applies to the Adler-32 implementation in Lustre.
Also, the cryptd and mcryptd templates have to pass through the flag
from their underlying algorithm.

And unlike the other helpers we don't require a <asm/dma-direct.h> as
this helper is a special case for ia64 only, and this keeps it as
simple as possible.
Signed-off-by: Christoph Hellwig <hch@lst.de>
phys_to_dma, dma_to_phys and dma_capable are helpers published by
architecture code for use of swiotlb and xen-swiotlb only. Drivers are
not supposed to use these directly, but use the DMA API instead.
Move these to a new asm/dma-direct.h helper, included by a
linux/dma-direct.h wrapper that provides the default linear mapping
unless the architecture wants to override it.
In the MIPS case the existing dma-coherent.h is reused for now as
untangling it will take a bit of work.

Construct the init thread stack in the linker script rather than doing it
by means of a union so that ia64's init_task.c can be got rid of.
The following symbols are then made available from INIT_TASK_DATA() linker
script macro:
init_thread_union
init_stack
INIT_TASK_DATA() also expands the region to THREAD_SIZE to accommodate the
size of the init stack. init_thread_union is given its own section so that
it can be placed into the stack space in the right order. I'm assuming
that the ia64 ordering is correct and that the task_struct is first and the
thread_info second.

So far, we loose the Exec property whenever we take permission
faults, as we always reconstruct the PTE/PMD from scratch. This
can be counter productive as we can end-up with the following
fault sequence:
X -> RO -> ROX -> RW -> RWX
Instead, we can lookup the existing PTE/PMD and clear the XN bit in the
new entry if it was already cleared in the old one, leadig to a much
nicer fault sequence:
X -> ROX -> RWX

We've so far eagerly invalidated the icache, no matter how
the page was faulted in (data or prefetch abort).
But we can easily track execution by setting the XN bits
in the S2 page tables, get the prefetch abort at HYP and
perform the icache invalidation at that time only.
As for most VMs, the instruction working set is pretty
small compared to the data set, this is likely to save
some traffic (specially as the invalidation is broadcast).

Calling __cpuc_coherent_user_range to invalidate the icache on
a PIPT icache machine has some pointless overhead, as it starts
by cleaning the dcache to the PoU, while we're guaranteed to
have already cleaned it to the PoC.
As KVM is the only user of such a feature, let's implement some
ad-hoc cache flushing in kvm_mmu.h. Should it become useful to
other subsystems, it can be moved to a more global location.

According to the comment added to exynos_dt_pmu_match[] in commit
8b283c0254 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"),
the RTC is not able to wake up the system through the PMU on Exynos5410,
unlike Exynos5420.
However, when the RTC DT node got added, it was a straight copy of
the Exynos5420 node, which now causes a warning from dtc.
This removes the incorrect interrupt-parent, which should get the
interrupt working and avoid the warning.

Pull "ASPEED device tree updates for 4.16" from Joel Stanley:
Clock driver support:
Rework all platforms to use proper clock bindings. Linux should now boot
upstream kernels on ast2400 and ast2500 platforms without out of tree
patches.
New systems:
Witherspoon: OpenPower Power9 server manufactured by IBM that uses the ASPEED ast2500
Zaius: OpenPower Power9 server manufactured by Invatech that uses the ASPEED ast2500
Q71L: Intel Xeon server manufactured by Qanta that uses the ASPEED ast2400
We also see updates to the Palmetto and Romulus systems to bring them in
line with the functionality of those above.
The systems take advantage of recently added drivers for LPC Snoop
device and the PWM/Tachometer fan controller.
OpenBMC flash layout:
The flash layout used OpenBMC systems is added and the device trees now
use it.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve as a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

MPP7 is currently muxed as "gpio", but this function doesn't exist for
MPP7, only "gpo" is available. This causes the following error:
kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7
pinctrl core: failed to register map default (6): invalid type given
kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22
kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22
kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver
kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22
So the pinctrl driver is not probed, all device drivers (including the
UART driver) do a -EPROBE_DEFER, and therefore the system doesn't
really boot (well, it boots, but with no UART, and no devices that
require pin-muxing).
Back when the Device Tree file for this board was introduced, the
definition was already wrong. The pinctrl driver also always described
as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11,
a hog pin failing to be muxed was turned from a simple warning to a
hard error that caused the entire pinctrl driver probe to bail
out. This is probably the result of commit 6118714275 ("pinctrl:
core: Fix pinctrl_register_and_init() with pinctrl_enable()").
This commit fixes the Device Tree to use the proper "gpo" function for
MPP7, which fixes the boot of OpenBlocks A7, which was broken since
Linux 4.11.

The EB MP board probably has a character LCD but the board manual does
not really state which IRQ it has assigned to this device. The invalid
assignment was a mistake by me during submission of the DTSI where I was
looking for the reference, didn't find it and didn't fill it in.
Delete this for now: it can probably be fixed but that requires access
to the actual board for some trial-and-error experiments.

A random assortment of improvements.
GPIO device nodes are added for the AXP813/AXP818 PMICs, meaning we can
finally use the GPIO pins on the PMICs. The LDOs on the GPIO pins can
also be properly muxed and guarded.
EMAC Ethernet support is enabled for more H3 boards, and also for the
A83T, following the return of the bindings in 4.15, after a last minute
revert in 4.13. This will make the H3/A83T boards much more useful in
headless applications.
Two new boards are introduced. The Orange Pi R1 is a small board with
two Ethernet interfaces (one EMAC-based and one USB-based) and a WiFi
chip. This board is fully supported, with the exception of TV-out on
the expansion header, which will not be enabled by default. The WiFi
chip (RTL8189FTV) requires an out-of-tree driver. The Libre Computer
Board ALL-H3-CC H3 version is a newcomer to the Allwinner SBC space,
which was mostly represented by a bunch of fruit-Pis. It is mostly
supported, with the exception of HDMI and camera sensor interface,
which have not been implemented yet.
Two minor patches enable the audio codec on the A13 Olinuxino, and
HDMI output on the pcDuino3 Nano.

Chris Paterson says "The current R-Car Gen2 device trees define the CPU
critical temperature as 115°C.
The R-Car hardware manuals state that Tc = –40°C to +105°C. The thermal
sensor has an accuracy of ±5°C and there can be a temperature
difference of 1 or 2 degrees between Tjmax and the thermal sensor due
to the location of the latter.
This means that 95°C is a safer value to use.
This value should also apply to r8a7792 but thermal sensor support has
not been added yet."

- Correct TPU register block size
Geert Uytterhoven says "The Timer Pulse Unit has registers that lie
outside the declared register block. Enlarge the register block size to
fix this.
This was probably based on the old platform code, which also assumed a
register block size of 0x100."

The display pipeline on the A83T is mainly composed of the mixers and
TCONs, plus various encoders.
Let's add the first mixer and TCON to the DTSI since the only board I have
can use only the LVDS output on the first TCON. The other parts will be
added eventually.

Fixes this time include mostly device tree changes, as usual,
the notable ones include:
- A number of patches to fix most of the remaining DTC warnings
that got introduced when DTC started warning about some
obvious mistakes. We still have some remaining warnings that
probably may have to wait until 4.16 to get fixed while we
try to figure out what the correct contents should be.
- On Allwinner A64, Ethernet PHYs need a fix after a mistake in
coordination between patches merged through multiple branches.
- Various fixes for PMICs on allwinner based boards
- Two fixes for ethernet link detection on some Renesas machines
- Two stability fixes for rockchip based boards
Aside from device-tree, two other areas got fixes for older
problems:
- For TI Davinci DM365, a couple of fixes were needed to repair
the MMC DMA engine support, apparently this has been broken for
a while.
- One important fix for all Allwinner chips with the PMIC driver
as a loadable module.

First, one fix that adds proper regulator references for the EMAC
external PHYs on A64 boards. The EMAC bindings were developed for 4.13,
but reverted at the last minute. They were finalized and brought back
for 4.15. However in the time between, regulator support for the A64
boards was merged. When EMAC device tree changes were reintroduced,
this was not taken into account.
Second, a patch that adds OF based modalias uevent for RSB slave devices.
This has been missing since the introduction of RSB, and recently with
PMIC regulator support introduced for the A64, has been seen affecting
distributions, which have the all-important PMIC mfd drivers built as
modules, which then don't get loaded.
Other minor cleanups include final conversion of raw indices to CCU
binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the
A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero
Plus2, and adding a missing compatible for the PMIC on the TBS A711

"AT24 updates for 4.16 merge window
The driver has been converted to using regmap instead of raw i2c and
smbus calls which shrank the code significantly.
Device tree binding document has been cleaned up. Device tree support in
the driver has been improved and we now support all at24 models as well
as two new DT properties (no-read-rollover and wp-gpios).
We no longer user unreadable magic values for driver data as the way it
was implemented caused problems for some EEPROM models - we switched to
regular structs.
Aside from that, there's a bunch of coding style fixes and minor
improvements all over the place."

We currently check if the VM has a userspace irqchip in several places
along the critical path, and if so, we do some work which is only
required for having an irqchip in userspace. This is unfortunate, as we
could avoid doing any work entirely, if we didn't have to support
irqchip in userspace.
Realizing the userspace irqchip on ARM is mostly a developer or hobby
feature, and is unlikely to be used in servers or other scenarios where
performance is a priority, we can use a refcounted static key to only
check the irqchip configuration when we have at least one VM that uses
an irqchip in userspace.

The NCR, MDM_CTL* and AUD registers manipulate the state of external
signals (eg, the RTS, DTR signals and the ethernet oscillator enable
signal) or indicate the state of external signals (eg, CTS, DSR).
Where these registers can be written, the current value can be read
back, which relieves us from having to maintain a software copy of
the current state.
Model these registers as fixed-direction GPIO registers.

Add a GPIO driver for the board control register/board status register
for the sa1100/assabet platform. This allows us to transition a range
of drivers to use the gpiod APIs rather than the platform private
ASSABET_BCR_* interfaces.
