4a6c971a06 vfio/fsl-mc: Use GFP_KERNEL_ACCOUNT for userspace persistent allocations
Use GFP_KERNEL_ACCOUNT for userspace persistent allocations.

The GFP_KERNEL_ACCOUNT option lets the memory allocator know that this
is untrusted allocation triggered from userspace and should be a subject
of kmem accounting, and as such it is controlled by the cgroup
mechanism.

0886196ca8 vfio: Use GFP_KERNEL_ACCOUNT for userspace persistent allocations
Use GFP_KERNEL_ACCOUNT for userspace persistent allocations.

The GFP_KERNEL_ACCOUNT option lets the memory allocator know that this
is untrusted allocation triggered from userspace and should be a subject
of kmem accounting, and as such it is controlled by the cgroup
mechanism.

The way to find the relevant allocations was for example to look at the
close_device function and trace back all the kfrees to their
allocations.

83ff6095ec vfio/mlx5: Allow loading of larger images than 512 MB
Allow loading of larger images than 512 MB by dropping the arbitrary
hard-coded value that we have today and move to use the max device
loading value which is for now 4GB.

As part of that we move to use the GFP_KERNEL_ACCOUNT option upon
allocating the persistent data of mlx5 and rely on the cgroup to provide
the memory limit for the given user.

The GFP_KERNEL_ACCOUNT option lets the memory allocator know that this
is untrusted allocation triggered from userspace and should be a subject
of kmem accounting, and as such it is controlled by the cgroup
mechanism.

b7f1a141f3 MAINTAINERS: step down as vfio reviewer
As my focus has shifted in recent months, my involvement with vfio has
decreased to occasionally reviewing some simpler patches, which is
probably less than you'd expect when you cc: someone for review.

Given that I currently don't have spare time to invest in looking at
vfio things, let's adjust the entry to match reality.

Pull another io_uring fix from Jens Axboe:
 "Just a single fix for a regression that happened in this release due
  to a poll change. Normally I would've just deferred it to next week,
  but since the original fix got picked up by stable, I think it's
  better to just send this one off separately.

  The issue is around the poll race fix, and how it mistakenly also got
  applied to multishot polling. Those don't need the race fix, and we
  should not be doing any reissues for that case. Exhaustive test cases
  were written and committed to the liburing regression suite for the
  reported issue, and additions for similar issues"

f3bbac3247 ext4: deal with legacy signed xattr name hash values
We potentially have old hashes of the xattr names generated on systems
with signed 'char' types.  Now that everybody uses '-funsigned-char',
those hashes will no longer match.

This only happens if you use xattrs names that have the high bit set,
which probably doesn't happen in practice, but the xfstest generic/454
shows it.

Instead of adding a new "signed xattr hash filesystem" bit and having to
deal with all the possible combinations, just calculate the hash both
ways if the first one fails, and always generate new hashes with the
proper unsigned char version.

8caa03f10b io_uring/poll: don't reissue in case of poll race on multishot request
A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.

A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests.

dc18175938 Thermal control fix for 6.2-rc5
Modify __thermal_cooling_device_register() to make it call
 put_device() after invoking device_register() and fix up a few
 error paths calling thermal_cooling_device_destroy_sysfs()
 unnecessarily (Viresh Kumar).

1ed46384f8 ARM: SoC DT and driver fixes 6.2
Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
 including:
 
  - A regression fix for SDHCI controllers on Inforce 6540, and
    another SDHCI fix on SM8350
 
  - Reenable cluster idle on sm8250 after the the code fix is upstream
 
  - multiple fixes for the QMP PHY binding, needing an incompatible
    dt change
 
  - The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
    6P, to avoid instabilities caused by use of protected memory regions
 
  - Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
    clock error
 
  - A couple of verdin-imx8mm DT fixes for audio playback support
 
  - Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
 
  - Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
    eMMC CMD8 CRC error in HS400ES/HS400 mode
 
 The remaining ARM and RISC-V platforms only have very few
 smaller dts bugfixes this time:
 
  - A fix for the SiFive unmatched board's PCI memory space
 
  - A revert to fix a regression with GPIO on Marvell Armada
 
  - A fix for the UART address on Marvell AC5
 
  - Missing chip-select phandles for stm32 boards
 
  - Selecting the correct clock for the sam9x60 memory controller
 
  - Amlogic based Odroid-HC4 needs a revert to restore USB
    functionality.
 
 And finally, there are some minor code fixes:
 
  - Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
    firmware
 
  - memory controller driver fixes for an OMAP regression and older bugs
    on tegra, atmel and mvebu
 
  - reset controller fixes for ti-sci and uniphier platforms
 
  - ARM SCMI firmware fixes for a couple of rare corner cases
 
  - Qualcomm platform driver fixes for incorrect error handling and a
    backwards compatibility fix for the apr driver using older dtb
 
  - NXP i.MX SoC driver fixes for HDMI output, error handling in the imx8
    soc-id and missing reference counting on older cpuid code

56d8e3180c io_uring/msg_ring: fix flagging remote execution
There is a couple of problems with queueing a tw in io_msg_ring_data()
for remote execution. First, once we queue it the target ring can
go away and so setting IORING_SQ_TASKRUN there is not safe. Secondly,
the userspace might not expect IORING_SQ_TASKRUN.

Extract a helper and uniformly use TWA_SIGNAL without TWA_SIGNAL_NO_IPI
tricks for now, just as it was done in the original patch.

Commit ca07e1c1e4 ("drivers:usb:fsl:Make fsl ehci drv an independent
driver module") changed DRV_NAME which was used for MODULE_ALIAS as well.
Starting from this the module alias didn't match the platform device
name created in fsl-mph-dr-of.c
Change DRV_NAME to match the driver name for host mode in fsl-mph-dr-of.
This is needed for module autoloading on ls1021a.

300b655db1 tcp: fix rate_app_limited to default to 1
The initial default value of 0 for tp->rate_app_limited was incorrect,
since a flow is indeed application-limited until it first sends
data. Fixing the default to be 1 is generally correct but also
specifically will help user-space applications avoid using the initial
tcpi_delivery_rate value of 0 that persists until the connection has
some non-zero bandwidth sample.

3daed6345d VMCI: Use threaded irqs instead of tasklets
The vmci_dispatch_dgs() tasklet function calls vmci_read_data()
which uses wait_event() resulting in invalid sleep in an atomic

Use threaded irqs to fix this issue and completely remove usage
of tasklets.

aaca766c77 misc: fastrpc: Pass bitfield into qcom_scm_assign_mem
The srcvm parameter of qcom_scm_assign_mem is a pointer to a bitfield of
VMIDs. The  bitfield is updated with which VMIDs have permissions
after the qcom_scm_assign_mem call. This makes it simpler for clients to
make qcom_scm_assign_mem calls later, they always pass in same srcvm
bitfield and do not need to closely track whether memory was originally
shared.

When restoring permissions to HLOS, fastrpc is incorrectly using the
first VMID directly -- neither the BIT nor the other possible VMIDs the
memory was already assigned to.  We already have a field intended for
this purpose: "perms" in the struct fastrpc_channel_ctx, but it was
never used. Start using the perms field.
