Pull 9p updates from Eric Van Hensbergen:
"This includes a number of patches addressing improvements in the cache
portions of the 9p client.
The biggest improvements have to do with fixing handling of inodes and
eliminating duplicate structures and unnecessary allocation/release of
inode structures and many associated unnecessary protocol traffic.
This also dramatically reduced code complexity across the code and
sets us up to add proper temporal cache capabilities"

fs/9p: fix dups even in uncached mode

git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse updates from Miklos Szeredi:
- Add passthrough mode for regular file I/O.
This allows performing read and write (also via memory maps) on a
backing file without incurring the overhead of roundtrips to
userspace. For now this is only allowed to privileged servers, but
this limitation will go away in the future (Amir Goldstein)
- Fix interaction of direct I/O mode with memory maps (Bernd Schubert)
- Export filesystem tags through sysfs for virtiofs (Stefan Hajnoczi)
- Allow resending queued requests for server crash recovery (Zhao Chen)
- Misc fixes and cleanups

The test type "make_warnings_file" should have no mandatory configuration
parameters other than the ones required by the "build" test type, because
its purpose is to create a file with build warnings that may or may not be
used by other subsequent tests. Currently, the only way to use it as a
stand-alone test is by setting POWER_CYCLE, CONSOLE, SSH_USER,
BUILD_TARGET, TARGET_IMAGE, REBOOT_TYPE and GRUB_MENU.

The recent introduction of the ACP/PSP communication for IRAM/DRAM fence

The signed_fw_image member of struct sof_amd_acp_desc is used to enable
signed firmware support in the driver via the acp_sof_quirk_table.
In preparation to support additional use cases of the quirk table (i.e.
adding new flags), move signed_fw_image to a new struct acp_quirk_entry
and update all references to it accordingly.
No functional changes intended.

Pull bcachefs updates from Kent Overstreet:
- Subvolume children btree; this is needed for providing a userspace
interface for walking subvolumes, which will come later
- Lots of improvements to directory structure checking
- Improved journal pipelining, significantly improving performance on
high iodepth write workloads
- Discard path improvements: the discard path is more efficient, and no
longer flushes the journal unnecessarily
- Buffered write path can now avoid taking the inode lock
- new mm helper: memalloc_flags_{save|restore}
- mempool now does kvmalloc mempools

Taking the ctx lock is not enough to use the deferred request completion
infrastructure, it'll get queued into the list but no one would expect
it there, so it will sit there until next io_submit_flush_completions().
It's hard to care about the cancellation path, so complete it via tw.

The bug can be triggered by sending an amdgpu_cs_wait_ioctl
to the AMDGPU DRM driver on any ASICs with valid context.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:
static void Syzkaller2(int fd)
{
union drm_amdgpu_ctx arg1;
union drm_amdgpu_wait_cs arg2;
arg1.in.op = AMDGPU_CTX_OP_ALLOC_CTX;
ret = drmIoctl(fd, 0x140106442 /* amdgpu_ctx_ioctl */, &arg1);
arg2.in.handle = 0x0;
arg2.in.timeout = 0x2000000000000;
arg2.in.ip_type = AMD_IP_VPE /* 0x9 */;
arg2->in.ip_instance = 0x0;
arg2.in.ring = 0x0;
arg2.in.ctx_id = arg1.out.alloc.ctx_id;
drmIoctl(fd, 0xc0206449 /* AMDGPU_WAIT_CS * /, &arg2);
}
The ioctl AMDGPU_WAIT_CS without previously submitted job could be assumed that
the error should be returned, but the following commit 1decbf6bb0b4dc56c9da6c5e57b994ebfc2be3aa
modified the logic and allowed to have sched_rq equal to NULL.
As a result when there is no job the ioctl AMDGPU_WAIT_CS returns success.
The change fixes null-ptr-deref in init entity and the stack below demonstrates
the error condition:

A patch to resolve an issue was found in MediaTek's GPL-licensed SDK:
In the mtk_ppe_stop() function, the PPE scan mode is not disabled before
disabling the PPE. This can potentially lead to a hang during the process
of disabling the PPE.
Without this patch, the PPE may experience a hang during the reboot test.

Raw NAND
The main series brought is an update of the Broadcom support to support
all BCMBCA SoCs and their specificity (ECC, write protection,
configuration straps), plus a few misc fixes and changes in the main
driver. Device tree updates are also part of this PR, initially because
of a misunderstanding on my side.
The STM32_FMC2 controller driver is also upgraded to properly support
MP1 and MP25 SoCs.
A new compatible is added for an Atmel flavor.
Among all these feature changes, there is as well a load of continuous
read related fixes, avoiding more corner conditions and clarifying the
logic. Finally a few miscellaneous fixes are made to the core, the
lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as
final one in the Hynix vendor driver.
SPI-NAND
The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for W25N04KV
chips.

commit 64f6a5d1922b ("container_of: add container_of_const()

it so that we don't accidentally cast away the const from our
state pointers.
The only thing I don't particularly like about container_of_const()
is that it still accepts void* in addition to the proper pointer
types, but that's how most other things in C work anyway so I
guess we can live with it.
And while at it rename the macro arguments to be a bit more
descriptive than just 'x'.

Commit 0499a78369ad ("ARM64: Dynamically allocate cpumasks and increase
supported CPUs to 512") changed the handling of cpumasks on ARM 64bit,
what resulted in the strange issues and warnings during cpufreq-dt
initialization on some big.LITTLE platforms.
This was caused by mixing OPPs between big and LITTLE cores, because
OPP-sharing information between big and LITTLE cores is computed on
cpumask, which in turn was not zeroed on allocation. Fix this by
switching to zalloc_cpumask_var() call.

In converting the XFS code from GFP_NOFS to scoped contexts, we
converted the quota radix tree to GFP_KERNEL. Unfortunately, it was
not clearly documented that this set was because there is a
dependency on the quotainfo->qi_tree_lock being taken in memory
reclaim to remove dquots from the radix tree.
In hindsight this is obvious, but the radix tree allocations on
insert are not immediately obvious, and we avoid this for the inode
cache radix trees by using preloading and hence completely avoiding
the radix tree node allocation under tree lock constraints.
Hence there are a few solutions here. The first is to reinstate
GFP_NOFS for the radix tree and add a comment explaining why
GFP_NOFS is used. The second is to use memalloc_nofs_save() on the
radix tree insert context, which makes it obvious that the radix
tree insert runs under GFP_NOFS constraints. The third option is to
simply replace the radix tree and it's lock with an xarray which can
do memory allocation safely in an insert context.
The first is OK, but not really the direction we want to head. The
second is my preferred short term solution. The third - converting
XFS radix trees to xarray - is the longer term solution.
Hence to fix the regression here, we take option 2 as it moves us in
the direction we want to head with memory allocation and GFP_NOFS
removal.
