Currently, the x86 JIT handling PROBE_MEM32 tagged accesses is not
equipped to handle atomic accesses into PTR_TO_ARENA, as no PROBE_MEM32
tagging is performed and no handling is enabled for them.
This will lead to unsafety as the offset into arena will dereferenced
directly without turning it into a base + offset access into the arena
region.
Since the changes to the x86 JIT will be fairly involved, for now,
temporarily disallow use of PTR_TO_ARENA as the destination operand for
atomics until support is added to the JIT backend.
Fixes: 2fe99eb0cc ("bpf: Add x86-64 JIT support for PROBE_MEM32 pseudo instructions.")

Since smb2_query_eas() reads EA and uses cached directory,
open_cached_dir() should request FILE_READ_EA access.
Otherwise listxattr() and getxattr() will fail with EACCES
(0xc0000022 STATUS_ACCESS_DENIED SMB status).

Several users have reported this log getting dumped too regularly to
kernel log. The likely root cause has been identified, and it suggests
that this situation is expected for some configurations
(for example SMB2.1).
Since the function returns appropriately even for such cases, it is
fairly harmless to make this a debug log. When needed, the verbosity
can be increased to capture this log.

Some code paths for querying server interfaces make a false
assumption that it will only get called for SMB3+. Since this
function now can get called from a generic code paths, the correct
thing to do is to have specific handler for this functionality
per SMB dialect, and call this handler.
This change adds such a handler and implements this handler only
for SMB 3.0 and 3.1.1.

We found a issue on production environment while using NVMe over RDMA,
admin_q reconnect failed forever while remote target and network is ok.
After dig into it, we found it may caused by a ABBA deadlock due to tag
allocation. In my case, the tag was hold by a keep alive request
waiting inside admin_q, as we quiesced admin_q while reset ctrl, so the
request maked as idle and will not process before reset success. As
fabric_q shares tagset with admin_q, while reconnect remote target, we
need a tag for connect command, but the only one reserved tag was held
by keep alive command which waiting inside admin_q. As a result, we
failed to reconnect admin_q forever. In order to fix this issue, I
think we should keep two reserved tags for admin queue.

and locking guard macros
- New ALSA core kunit test
ASoC:
- SoundWire support for AMD ACP 6.3 systems
- Support for reporting version information for AVS firmware
- Support DSPless mode for Intel Soundwire systems
- Support for configuring CS35L56 amplifiers using EFI calibration
data
- Log which component is being operated on as part of power management
trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
HD- and USB-audio:
- More Cirrus HD-audio codec support
- TAS2781 HD-audio codec fixes
- Scarlett2 mixer fixes

- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:

know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)

runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)

CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)

Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of
4 pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance

separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof

- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)

No core changes this time around.
New drivers:
- New driver for Renesas R8A779H0 also known as R-Car V4M.
- New driver for the Awinic AW9523/B I2C GPIO expander.
I found this living out-of-tree in OpenWrt as an upstream
attempt had stalled on the finishing line, so I picked it
up and finished the job.
Improvements:
- The Nomadik pin control driver was for years re-used out of
tree for the ST STA chips, and now the IP was re-used in a
MIPS automotive SoC called MobilEyeq5, so it has been split
in pin control and GPIO drivers so the latter can be reused
by MobilEyeq5. (Along with a long list of cleanups.)
- A lot of overall cleanup and tidying up.

Fix a bug where nilfs_get_block() returns a successful status when
searching and inserting the specified block both fail inconsistently. If
this inconsistent behavior is not due to a previously fixed bug, then an
unexpected race is occurring, so return a temporary error -EAGAIN instead.
This prevents callers such as __block_write_begin_int() from requesting a
read into a buffer that is not mapped, which would cause the BUG_ON check
for the BH_Mapped flag in submit_bh_wbc() to fail.

Patch series "nilfs2: fix kernel bug at submit_bh_wbc()".
This resolves a kernel BUG reported by syzbot. Since there are two
flaws involved, I've made each one a separate patch.
The first patch alone resolves the syzbot-reported bug, but I think
both fixes should be sent to stable, so I've tagged them as such.
This patch (of 2):
Syzbot has reported a kernel bug in submit_bh_wbc() when writing file data
to a nilfs2 file system whose metadata is corrupted.
There are two flaws involved in this issue.
The first flaw is that when nilfs_get_block() locates a data block using
btree or direct mapping, if the disk address translation routine
nilfs_dat_translate() fails with internal code -ENOENT due to DAT metadata
corruption, it can be passed back to nilfs_get_block(). This causes
nilfs_get_block() to misidentify an existing block as non-existent,
causing both data block lookup and insertion to fail inconsistently.
The second flaw is that nilfs_get_block() returns a successful status in
this inconsistent state. This causes the caller __block_write_begin_int()
or others to request a read even though the buffer is not mapped,
resulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc()
failing.
This fixes the first issue by changing the return value to code -EINVAL
when a conversion using DAT fails with code -ENOENT, avoiding the
conflicting condition that leads to the kernel bug described above. Here,
code -EINVAL indicates that metadata corruption was detected during the
block lookup, which will be properly handled as a file system error and
converted to -EIO when passing through the nilfs2 bmap layer.

For special files in S_IFBLK/S_IFCHR/S_IFIFO type, we already have
ocfs2_setattr and ocfs2_getattr enabled. It's confusing for user space if
it can use setattr/getattr to control one attribute appointed but can not
list attributes using listxattr for above type files:
$ mknod /mnt/b b 0 0
$ setfattr -h -n trusted.name -v 0xbabe /mnt/b
$ getfattr -n trusted.name /mnt/b
getfattr: Removing leading '/' from absolute path names
trusted.name=0sur4=
$ getfattr -m trusted /mnt/b
$
Fix it by enabling ocfs2_listxattr for ocfs2_special_file_iops. After the
commit, fstests/generic/062 will pass.

The behavior of mmap on riscv is defined to not provide an address that
uses more bits than the hint address, if provided. Make the tests
reflect that.

On riscv it is guaranteed that the address returned by mmap is less than
the hint address. Allow mmap to return an address all the way up to
addr, if provided, rather than just up to the lower address space.
This provides a performance benefit as well, allowing mmap to exit after
checking that the address is in range rather than searching for a valid
address.
It is possible to provide an address that uses at most the same number
of bits, however it is significantly more computationally expensive to
provide that number rather than setting the max to be the hint address.
There is the instruction clz/clzw in Zbb that returns the highest set bit
which could be used to performantly implement this, but it would still
be slower than the current implementation. At worst case, half of the
address would not be able to be allocated when a hint address is
provided.

Passing a NULL buffer into the lsm_get_self_attr() syscall is a valid
way to quickly determine the minimum size of the buffer needed to for
the syscall to return all of the LSM attributes to the caller.
Unfortunately we/I broke that behavior in commit d7cf3412a9
("lsm: consolidate buffer size handling into lsm_fill_user_ctx()")
such that it returned an error to the caller; this patch restores the
original desired behavior of using the NULL buffer as a quick way to

Create a type drm_edid_ident as the identity of an EDID. Currently it
contains panel id and monitor name.
Create a function that can match a given EDID and an identity:
1. Reject if the panel id doesn't match.
2. If name is not null in identity, try to match it in the detailed timing
blocks. Note that some panel vendors put the monitor name after
EDID_DETAIL_MONITOR_STRING.

It's found that some panels have variants that they share the same panel id
although their EDID and names are different. Besides panel id, now we need
more information from the EDID base block to distinguish these panel
variants.
Add drm_edid_read_base_block() to return the EDID base block, which is
wrapped in struct drm_edid.
Caller can further use it to get panel id or check if the block contains
certain strings, such as panel name.
Merge drm_edid_get_panel_id() and edid_extract_panel_id() into one
function.
