Pull btrfs fixes from David Sterba:
 "A few more fixes for a late rc:

   - fix lockdep complaint on 32bit arches and also remove an unsafe
     memory use due to device vs filesystem lifetime

   - two fixes for free space tree:

      * race during log replay and cache rebuild, now more likely to
        happen due to changes in this dev cycle

      * possible free space tree corruption with online conversion
        during initial tree population"

1bea2a937d soc: litex: Properly depend on HAS_IOMEM
The LiteX SOC controller driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.

This causes the driver to be enable under make ARCH=um allyesconfig,
even though it won't build.

By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

a9cbbb80e3 tty: avoid using vfs_iocb_iter_write() for redirected console writes
It turns out that the vfs_iocb_iter_{read,write}() functions are
entirely broken, and don't actually use the passed-in file pointer for
IO - only for the preparatory work (permission checking and for the
write_iter function lookup).

That worked fine for overlayfs, which always builds the new iocb with
the same file pointer that it passes in, but in the general case it ends
up doing nonsensical things (and could cause an iterator call that
doesn't even match the passed-in file pointer).

This subtly broke the tty conversion to write_iter in commit
9bb48c82ac ("tty: implement write_iter"), because the console
redirection didn't actually end up redirecting anything, since the
passed-in file pointer was basically ignored, and the actual write was
done with the original non-redirected console tty after all.

The main visible effect of this is that the console messages were no
longer logged to /var/log/boot.log during graphical boot.

Fix the issue by simply not using the vfs write "helper" function at
all, and just redirecting the write entirely internally to the tty
layer.  Do the target writability permission checks when actually
registering the target tty with TIOCCONS instead of at write time.

cd92cdb9c8 null_blk: cleanup zoned mode initialization
To avoid potential compilation problems, replaced the badly written
MB_TO_SECTS() macro (missing parenthesis around the argument use) with
the inline function mb_to_sects(). And while at it, simplify the
calculation of the total number of zones of the device using the
round_up() macro.

ba839b7598 drm/nouveau/kms/gk104-gp1xx: Fix > 64x64 cursors
While we do handle the additional cursor sizes introduced in NVE4, it looks
like we accidentally broke this when converting over to use Nvidia's
display headers. Since we now use NVVAL in dispnv50/head907d.c in order to
format the value for the cursor layout and NVD9 only had one byte reserved
vs. the 2 bytes reserved in later generations, we end up accidentally
stripping the second bit in the cursor layout format parameter - causing us
to set the wrong cursor size.

This fixes that by adding our own curs_set hook for 917d which uses the
NV917D headers.

fd55b61ebd drm/nouveau/dispnv50: Restore pushing of all data.
Commit f844eb485e introduced a regression for
NV50, which lead to visual artifacts, tearing and eventual crashes.

In the changes of f844eb485e only the first line
was correctly translated to the new NVIDIA header macros:

-		PUSH_NVSQ(push, NV827C, 0x0110, 0,
-					0x0114, 0);
+		PUSH_MTHD(push, NV827C, SET_PROCESSING,
+			  NVDEF(NV827C, SET_PROCESSING, USE_GAIN_OFS, DISABLE));

The lower part ("0x0114, 0") was probably omitted by accident.

This patch restores the push of the missing data and fixes the regression.

3a7efd1ad2 io_uring: reinforce cancel on flush during exit
What 84965ff8a8 ("io_uring: if we see flush on exit, cancel related tasks")
really wants is to cancel all relevant REQ_F_INFLIGHT requests reliably.
That can be achieved by io_uring_cancel_files(), but we'll miss it
calling io_uring_cancel_task_requests(files=NULL) from io_uring_flush(),
because it will go through __io_uring_cancel_task_requests().

Just always call io_uring_cancel_files() during cancel, it's good enough
for now.

====================
mlxsw: Various fixes

Patch #1 fixes wrong invocation of mausezahn in a couple of selftests.
The tests started failing after Fedora updated their libnet package from
version 1.1.6 to 1.2.1. With the fix the tests pass regardless of libnet
version.

Patch #2 fixes an issue in the mirroring to CPU code that results in
policer configuration being overwritten.

b6f6881aaf mlxsw: spectrum_span: Do not overwrite policer configuration
The purpose of the delayed work in the SPAN module is to potentially
update the destination port and various encapsulation parameters of SPAN
agents that point to a VLAN device or a GRE tap. The destination port
can change following the insertion of a new route, for example.

SPAN agents that point to a physical port or the CPU port are static and
never change throughout the lifetime of the SPAN agent. Therefore, skip
over them in the delayed work.

This fixes an issue where the delayed work overwrites the policer
that was set on a SPAN agent pointing to the CPU. Modifying the delayed
work to inherit the original policer configuration is error-prone, as
the same will be needed for any new parameter.

11df27f7fd selftests: forwarding: Specify interface when invoking mausezahn
Specify the interface through which packets should be transmitted so
that the test will pass regardless of the libnet version against which
mausezahn is linked.

7cfc4486e7 stmmac: intel: Configure EHL PSE0 GbE and PSE1 GbE to 32 bits DMA addressing
Fix an issue where dump stack is printed and Reset Adapter occurs when
PSE0 GbE or/and PSE1 GbE is/are enabled. EHL PSE0 GbE and PSE1 GbE use
32 bits DMA addressing whereas EHL PCH GbE uses 64 bits DMA addressing.

c64396cc36 A set of PI futex fixes:
- Address a longstanding issue where the user space part of the PI futex
     is not writeable. The kernel returns with inconsistent state which can
     in the worst case result in a UAF of a tasks kernel stack. The solution
     is to establish consistent kernel state which makes future operations
     on the futex fail because user space and kernel space state are
     inconsistent. Not a problem as PI futexes fundamentaly require a
     functional RW mapping and if user space pulls the rug under it, then it
     can keep the pieces it asked for.
 
   - Address an issue where the return value is incorrect in case that the
     futex was acquired after a timeout/signal made the waiter drop out of
     the rtmutex wait. In one of the corner cases the kernel returned an
     error code despite having successfully acquired the futex.

notes but directly, remove a WARN_ONCE() there that give us false

places.

00190bc087 amdgpu: fix clang build warning
clang warns about the -mhard-float command line arguments
on architectures that do not support this:

clang: error: argument unused during compilation: '-mhard-float' [-Werror,-Wunused-command-line-argument]

Move this into the gcc-specific arguments.

a119f87b86 Revert "drm/amdgpu/swsmu: drop set_fan_speed_percent (v2)"
On some boards the rpm interface apparently does not work at all
leading to the fan not spinning or spinning at strange speeds.
Revert this for now to fix 5.10, 5.11.  The follow on patch
fixes this properly for 5.12.

This reverts commit 8d6e65adc2.

772ea326a4 nvme-core: use list_add_tail_rcu instead of list_add_tail for nvme_init_ns_head
The "list" of nvme_ns_head is used as rcu list, now in nvme_init_ns_head
list_add_tail is used to add ns->siblings to the rcu list. It is not safe.
Should use list_add_tail_rcu instead of list_add_tail.

7485e08eec ARM: SoC fixes for v5.11, part 2
These are the current arm-soc bug fixes for linux-5.11. I already merged
 a larger set that just came in during the past three days but has not
 had much exposure in linux-next, so these are the ones I merged last week.
 
 Most of these are for the NXP i.MX platform (descriptions from their
 pull request):
 
  - Fix pcf2127 reset for imx7d-flex-concentrator board.
  - Fix i.MX6 suspend with Thumb-2 kernel.
  - Fix ethernet-phy address issue on imx6qdl-sr-som board.
  - Fix GPIO3 `gpio-ranges` on i.MX8MP.
  - Select SOC_BUS for IMX_SCU driver to fix build issue.
  - Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
    #pwm-cells conversion.
  - Fix duplicated bus node name for i.MX8MN SoC.
  - Fix reset register offset on LS1028A SoC.
  - Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
    index consistent with previous kernel version.
  - Selecting ARM_GIC_V3 on non-CP15 processors to fix one build failure
    with i.MX8M SoC driver.
  - Fix typos with status property on imx6qdl-kontron-samx6i board.
  - Fix duplicated regulator-name on imx6qdl-gw52xx board.
 
 Aside from i.MX, the bugfixes are all over the place:
 
  - Coccinelle found a refcount imbalance on integrator
  - defconfig fix for TI K3
  - A boot regression fix for ST ux500
  - A code preemption fix for the optee driver
  - USB DMA regression on Broadcom Stingray
  - A bogus boot time warning fix for at91 code

Merge tag 'media/v5.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 - a V4L2 core regression at videobuf2 when checking for single-plane
   dmabuf

 - a change at uAPI header v4l2-subdev.h, fixing a breakage as BIT()
   macro is not available in userspace

 - fix some regressions at RC core due to the usage of microseconds
   everywhere on it

 - a fix for a race condition at RC core

 - a rename on a newly-introduced kAPI symbol (v4l2_get_link_rate),
   currently used only by a single driver

 - Regression fixes for rcar-vin, cedrus, ite-cir, hantro, css, venus,
   and cec drivers.

757fed1d08 Revert "mm/slub: fix a memory leak in sysfs_slab_add()"
This reverts commit dde3c6b72a.

syzbot report a double-free bug. The following case can cause this bug.

 - mm/slab_common.c: create_cache(): if the __kmem_cache_create() fails,
   it does:

	out_free_cache:
		kmem_cache_free(kmem_cache, s);

 - but __kmem_cache_create() - at least for slub() - will have done

	sysfs_slab_add(s)
		-> sysfs_create_group() .. fails ..
		-> kobject_del(&s->kobj); .. which frees s ...

We can't remove the kmem_cache_free() in create_cache(), because other
error cases of __kmem_cache_create() do not free this.

So, revert the commit dde3c6b72a ("mm/slub: fix a memory leak in
sysfs_slab_add()") to fix this.
