RISC-V: Fix usage of memblock_enforce_memory_limit
memblock_enforce_memory_limit accepts the maximum memory size not the
maximum address that can be handled by kernel. Fix the function invocation
accordingly.

Fixes: 1bd14a66ee ("RISC-V: Remove any memblock representing unusable memory area")

e2ae634014 RISC-V Patches for the 5.11 Merge Window, Part 1
We have a handful of new kernel features for 5.11:
 
 * Support for the contiguous memory allocator.
 * Support for IRQ Time Accounting
 * Support for stack tracing
 * Support for strict /dev/mem
 * Support for kernel section protection
 
 I'm being a bit conservative on the cutoff for this round due to the
 timing, so this is all the new development I'm going to take for this
 cycle (even if some of it probably normally would have been OK).  There
 are, however, some fixes on the list that I will likely be sending along
 either later this week or early next week.
 
 There is one issue in here: one of my test configurations
 (PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of the
 .text.init alignment patch.  With any luck we'll sort out the issue, but
 given how many bugs get fixed all over the place and how unrelated those
 features seem my guess is that we're just running into something that's
 been lurking for a while and has already been fixed in the newer QEMU
 (though I wouldn't be surprised if it's one of these implicit
 assumptions we have in the boot flow).  If it was hardware I'd be
 strongly inclined to look more closely, but given that users can upgrade
 their simulators I'm less worried about it.
 
 There are two merge conflicts, both in build files.  They're both a bit
 clunky: arch/riscv/Kconfig is out of order (I have a script that's
 supposed to keep them in order, I'll fix it) and lib/Makefile is out of
 order (though GENERIC_LIB here doesn't mean quite what it does above).

a409ed156a This is the bulk of the GPIO changes for the v5.11 kernel cycle:
Core changes:
 
 - Retired the old set-up function for GPIO IRQ chips. All chips
   now use the template struct gpio_irq_chip and pass that to the core
   to be set up alongside the gpio_chip. We can finally get rid of
   the old cruft.
 
 - Some refactoring and clean up of the core code.
 
 - Support edge event timestamps to be stamped using REALTIME
   (wall clock) timestamps. We have found solid use cases for
   this, so we support it.
 
 New drivers:
 
 - MStar MSC313 GPIO driver.
 
 - HiSilicon GPIO driver.
 
 Driver improvements:
 
 - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
 
 - The mockup driver can now be probed from the device tree which
   is pretty useful for virtual prototyping of devices.
 
 - The Rcar driver now supports .get_multiple()
 
 - The MXC driver dropped some legacy and became a pure device
   tree client.
 
 - The Exar driver was moved over to the IDA interface for
   enumerating, and also switched over to using regmap for
   register access.

 "The largest part are for support of the newer mount API which has been
  needed for cifs/smb3 mounts for a long time due to the new API's
  better handling of remount, and better error reporting. There are
  three additional small cleanup patches for this being tested, that are
  not included yet.

  This series also includes addition of support for the SMB3 witness
  protocol which can provide important notifications from the server to
  client on server address or export or network changes. This can be
  useful for example in order to be notified before the failure - when a
  server's IP address changes (in the future it will allow us to support
  server notifications of when a share is moved).

  It also includes three patches for stable e.g. some that better handle
  some confusing error messages during session establishment"

09c0796adf Tracing updates for 5.11
The major update to this release is that there's a new arch config option called:
 CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it.
 All the ftrace callbacks now take a struct ftrace_regs instead of a struct
 pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then
 the ftrace_regs will have enough information to read the arguments of the
 function being traced, as well as access to the stack pointer. This way, if
 a user (like live kernel patching) only cares about the arguments, then it
 can avoid using the heavier weight "regs" callback, that puts in enough
 information in the struct ftrace_regs to simulate a breakpoint exception
 (needed for kprobes).
 
 New config option that audits the timestamps of the ftrace ring buffer at
 most every event recorded.  The "check_buffer()" calls will conflict with
 mainline, because I purposely added the check without including the fix that
 it caught, which is in mainline. Running a kernel built from the commit of
 the added check will trigger it.
 
 Ftrace recursion protection has been cleaned up to move the protection to
 the callback itself (this saves on an extra function call for those
 callbacks).
 
 Perf now handles its own RCU protection and does not depend on ftrace to do
 it for it (saving on that extra function call).
 
 New debug option to add "recursed_functions" file to tracefs that lists all
 the places that triggered the recursion protection of the function tracer.
 This will show where things need to be fixed as recursion slows down the
 function tracer.
 
 The eval enum mapping updates done at boot up are now offloaded to a work
 queue, as it caused a noticeable pause on slow embedded boards.
 
 Various clean ups and last minute fixes.

312dcaf967 Modules updates for v5.11
Summary of modules changes for the 5.11 merge window:
 
 - Fix a race condition between systemd/udev and the module loader.
   The module loader was sending a uevent before the module was fully
   initialized (i.e., before its init function has been called). This means
   udev can start processing the module uevent before the module has
   finished initializing, and some udev rules expect that the module has
   initialized already upon receiving the uevent. This resulted in some
   systemd mount units failing if udev processes the event faster than the
   module can finish init. This is fixed by delaying the uevent until after
   the module has called its init routine.
 
 - Make the linker array sections for kernel params and module version
   attributes more robust by switching to use the alignment of the type in
   question. Namely, linker section arrays will be constructed using the
   alignment required by the struct (using __alignof__()) as opposed to a
   specific value such as sizeof(void *) or sizeof(long). This is less
   likely to cause breakages should the size of the type ever change (from
   Johan Hovold)
 
 - Fix module state inconsistency by setting it back to GOING when a module
   fails to load and is on its way out (from Miroslav Benes)
 
 - Some comment and code cleanups (from Sergey Shtylyov)

be695ee29e The big ticket item here is support for msgr2 on-wire protocol, which
adds the option of full in-transit encryption using AES-GCM algorithm
 (myself).  On top of that we have a series to avoid intermittent
 errors during recovery with recover_session=clean and some MDS request
 encoding work from Jeff, a cap handling fix and assorted observability
 improvements from Luis and Xiubo and a good number of cleanups.  Luis
 also ran into a corner case with quotas which sadly means that we are

Pull overlayfs updates from Miklos Szeredi:

 - Allow unprivileged mounting in a user namespace.

   For quite some time the security model of overlayfs has been that
   operations on underlying layers shall be performed with the
   privileges of the mounting task.

   This way an unprvileged user cannot gain privileges by the act of
   mounting an overlayfs instance. A full audit of all function calls
   made by the overlayfs code has been performed to see whether they
   conform to this model, and this branch contains some fixes in this
   regard.

 - Support running on copied filesystem images by optionally disabling
   UUID verification.

 - Bug fixes as well as documentation updates.

ff49c86f27 f2fs-for-5.11-rc1
In this round, we've made more work into per-file compression support. For
 example, F2FS_IOC_GET|SET_COMPRESS_OPTION provides a way to change the
 algorithm or cluster size per file. F2FS_IOC_COMPRESS|DECOMPRESS_FILE provides
 a way to compress and decompress the existing normal files manually along with
 a new mount option, compress_mode=fs|user, which can control who compresses the
 data. Chao also added a checksum feature with a mount option so that we are able
 to detect any corrupted cluster. In addition, Daniel contributed casefolding
 with encryption patch, which will be used for Android devices.
 
 Enhancement:
  - add ioctls and mount option to manage per-file compression feature
  - support casefolding with encryption
  - support checksum for compressed cluster
  - avoid IO starvation by replacing mutex with rwsem
  - add sysfs, max_io_bytes, to control max bio size
 
 Bug fix:
  - fix use-after-free issue when compression and fsverity are enabled
  - fix consistency corruption during fault injection test
  - fix data offset for lseek
  - get rid of buffer_head which has 32bits limit in fiemap
  - fix some bugs in multi-partitions support
  - fix nat entry count calculation in shrinker
  - fix some stat information
 
 And, we've refactored some logics and fix minor bugs as well.

5b33afee93 nfp: move indirect block cleanup to flower app stop callback
The indirect block cleanup may cause control messages to be sent
if offloaded flows are present. However, by the time the flower app
cleanup callback is called txbufs are no longer available and attempts
to send control messages result in a NULL-pointer dereference in
nfp_ctrl_tx_one().

This problem may be resolved by moving the indirect block cleanup
to the stop callback, where txbufs are still available.

As suggested by Jakub Kicinski and Louis Peens.

d8a4ea350f octeontx2-af: Fix undetected unmap PF error check
Currently the check for an unmap PF error is always going to be false
because intr_val is a 32 bit int and is being bit-mask checked against
1ULL << 32.  Fix this by making intr_val a u64 to match the type at it
is copied from, namely npa_event_context->npa_af_rvu_ge.

219d04992b mptcp: push pending frames when subflow has free space
When multiple subflows are active, we can receive a
window update on subflow with no write space available.
MPTCP will try to push frames on such subflow and will
fail. Pending frames will be pushed only after receiving
a window update on a subflow with some wspace available.

Overall the above could lead to suboptimal aggregate
bandwidth usage.

Instead, we should try to push pending frames as soon as
the subflow reaches both conditions mentioned above.

We can finally enable self-tests with asymmetric links,
as the above makes them finally pass.

d652d5f1ee drm/edid: fix objtool warning in drm_cvt_modes()
Commit 991fcb77f4 ("drm/edid: Fix uninitialized variable in
drm_cvt_modes()") just replaced one warning with another.

The original warning about a possibly uninitialized variable was due to
the compiler not being smart enough to see that the case statement
actually enumerated all possible cases.  And the initial fix was just to
add a "default" case that had a single "unreachable()", just to tell the
compiler that that situation cannot happen.

However, that doesn't actually fix the fundamental reason for the
problem: the compiler still doesn't see that the existing case
statements enumerate all possibilities, so the compiler will still
generate code to jump to that unreachable case statement.  It just won't
complain about an uninitialized variable any more.

So now the compiler generates code to our inline asm marker that we told
it would not fall through, and end end result is basically random.  We
have created a bridge to nowhere.

And then, depending on the random details of just exactly what the
compiler ends up doing, 'objtool' might end up complaining about the
conditional branches (for conditions that cannot happen, and that thus
will never be taken - but if the compiler was not smart enough to figure
that out, we can't expect objtool to do so) going off in the weeds.

So depending on how the compiler has laid out the result, you might see
something like this:

    drivers/gpu/drm/drm_edid.o: warning: objtool: do_cvt_mode() falls through to next function drm_mode_detailed.isra.0()

and now you have a truly inscrutable warning that makes no sense at all
unless you start looking at whatever random code the compiler happened
to generate for our bare "unreachable()" statement.

IOW, don't use "unreachable()" unless you have an _active_ operation
that generates code that actually makes it obvious that something is not
reachable (ie an UD instruction or similar).

Solve the "compiler isn't smart enough" problem by just marking one of
the cases as "default", so that even when the compiler doesn't otherwise
see that we've enumerated all cases, the compiler will feel happy and
safe about there always being a valid case that initializes the 'width'
variable.

This also generates better code, since now the compiler doesn't generate
comparisons for five different possibilities (the four real ones and the
one that can't happen), but just for the three real ones and "the rest"
(which is that last one).

A smart enough compiler that sees that we cover all the cases won't care.

    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.

9805529ec5 ARM: device tree updates for 5.11
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
    meant for faster Chromebooks and tablets. It gets added along with
    its reference design.
 
  - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
    generation, also added along with its reference board.  This one is
    still based on Cortex-A75/A55.
 
  - Mediatek MT8167 is a version of the already supported MT8516 chip,
    both based on Cortex-A35. It gets added along with the "Pumpkin"
    single board computer, but is likely to also make its way into low-end
    tablets in the future.
 
 For the already supported chips, there are a number of new boards.

Pull ARM device tree updates from Arnd Bergmann:
 "Across all platforms, there is a continued move towards DT schema for
  validating the dts files. As a result there are bug fixes for mistakes
  that are found using these schema, in addition to warnings from the
  dtc compiler.

  As usual, many changes are for adding support for additional on-chip
  and on-board components in the machines we already support.

  The newly supported SoCs for this release are:

   - MStar Infinity2M, a low-end IP camera chip based on a dual-core
     Cortex-A7, otherwise similar to the Infinity chip we already
     support. This is also known as the SigmaStar SSD202D, and we add
     support for the Honestar ssd201htv2 development kit.

   - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
     (BMC), in the same family as the NPCM750. This gets used in the
     Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of
     which are added as well.

   - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
     Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
     GT-AC5300 high-end WiFi router based on this chip.

   - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
     meant for faster Chromebooks and tablets. It gets added along with
     its reference design.

   - Mediatek MT6779 (Helio P90) is a high-end phone chip from last
     year's generation, also added along with its reference board. This
     one is still based on Cortex-A75/A55.

   - Mediatek MT8167 is a version of the already supported MT8516 chip,
     both based on Cortex-A35. It gets added along with the "Pumpkin"
     single board computer, but is likely to also make its way into
     low-end tablets in the future.

  For the already supported chips, there are a number of new boards.
  Interestingly there are more 32-bit machines added this time than
  64-bit. Here is a brief list of the new boards:

   - Three new Mikrotik router variants based on Marvell Prestera

75f4d4544d devlink: use _BITUL() macro instead of BIT() in the UAPI header
The BIT() macro is not available for the UAPI headers. Moreover, it can
be defined differently in user space headers. Thus, replace its usage
with the _BITUL() macro which is already used in other macro definitions
in <linux/devlink.h>.

Merge tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

   - Qualcomm MSM8953 subdriver.

   - Qualcomm SDX55 subdriver.

   - Qualcomm SDX55 PMIC subdriver.

   - Ocelot Luton SoC subdriver.

   - Ocelot Serval SoC subdriver.

  Modularization:

   - The Meson driver can now be built as modules.

   - The Qualcomm driver(s) can now be built as modules.

  Incremental improvements:

   - The Intel driver now supports pin configuration for GPIO-related
     configurations.

   - A bunch of Renesas PFC drivers have been augmented with support for
     QSPI pins, groups and functions.

   - Non-critical fixes to the irq handling in the Allwinner Sunxi
     driver"

31f6551ad7 cifs: handle "guest" mount parameter
With the new mount API it can not handle empty strings for
mount parms ("guest" is mapped in userspace mount helper to
"user=") so we have to special case it as we do for the
password mount parm.

7eb000bdbe net: korina: fix return value
The ndo_start_xmit() method must not attempt to free the skb to transmit
when returning NETDEV_TX_BUSY. Therefore, make sure the
korina_send_packet() function returns NETDEV_TX_OK when it frees a packet.
