Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:
 "The major features are support for LPA2 (52-bit VA/PA with 4K and 16K
  pages), the dpISA extension and Rust enabled on arm64. The changes are
  mostly contained within the usual arch/arm64/, drivers/perf, the arm64
  Documentation and kselftests. The exception is the Rust support which
  touches some generic build files.

  Summary:

   - Reorganise the arm64 kernel VA space and add support for LPA2 (at
     stage 1, KVM stage 2 was merged earlier) - 52-bit VA/PA address

 - Lots of cleanups in ALSA core code with automatic kfree cleanup
   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
 
 Others:
 - Enhancement of virtio driver for audio control supports
 - Cleanups of legacy PM code with new macros
 - Firewire sound updates

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Consolidate interrupt related code in irq.c (Ilpo Järvinen)

   - Reduce kernel size by replacing sysfs resource macros with
     functions (Ilpo Järvinen)

   - Reduce kernel size by compiling sysfs support only when
     CONFIG_SYSFS=y (Lukas Wunner)

   - Avoid using Extended Tags on 3ware-9650SE Root Port to work around
     an apparent hardware defect (Jörg Wedekind)

  Resource management:

   - Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)

   - 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:

   - Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
     know how to return correctly to D0, and remove previous quirk that
     wasn't as specific (Daniel Drake)

   - Allow runtime PM when the driver enables it but doesn't need any
     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)

   - Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
     still don't advertise a legal size (Paul Menzel)

   - Ignore expected DPC Surprise Down errors on hot removal (Smita
     Koralahalli)

   - Block runtime suspend while handling AER errors to avoid races that
     prevent the device form being resumed from D3hot (Stanislaw
     Gruszka)

  Peer-to-peer DMA:

   - Use atomic XA allocation in RCU read section (Christophe JAILLET)

  ASPM:

   - Collect bits of ASPM-related code that we need even without
     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)

   - Return actual error code for pci_vntb_probe() failure (Yang
     Yingliang)

  Broadcom STB PCIe controller driver:

   - Fix MDIO write polling, which previously never waited for
     completion (Jonathan Bell)

  Cadence PCIe endpoint driver:

   - Clear the ARI "Next Function Number" of last function (Jasko-EXT
     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
     level (Johan Hovold)

   - Make DT 'msi-map-mask' optional, depending on how MSI interrupts
     are mapped (Johan Hovold)

   - Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
     configuration isn't tuned correctly for L0s (Johan Hovold)

   - Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
     separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
     SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
     Kozlowski)

   - 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)

   - Fix endpoint Resizable BAR to actually advertise the required 1MB
     size (Niklas Cassel)

  MicroSemi Switchtec management driver:

   - Release resources if the .probe() fails (Christophe JAILLET)

  Miscellaneous:

   - Make pcie_port_bus_type const (Ricardo B. Marliere)"

   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.

269cdf353b nilfs2: prevent kernel bug at submit_bh_wbc() 
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.

f2f26b4a84 nilfs2: fix failure to detect DAT corruption in btree and direct mappings 
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.

41e296f69f ocfs2: enable ocfs2_listxattr for special files 
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.

eaf0e7a3d2 lsm: handle the NULL buffer case in lsm_fill_user_ctx() 
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
correctly size the attribute buffer.

Change the size parameters in lsm_list_modules(), lsm_set_self_attr()
and lsm_get_self_attr() from size_t to u32. This avoids the need to
have different interfaces for 32 and 64 bit systems.

bf5e3a30f7 Revert "blk-lib: check for kill signal" 
This reverts commit 8a08c5fd89.

It turns out while this is a perfectly valid and long overdue thing to do
for user initiated discards / zeroing from the ioctl handler, it actually
breaks file system use of the discard helper by interrupting in places
the file system doesn't expect, and by leaving the bio chain in a state
that the file system callers of (at least) __blkdev_issue_discard do
not expect.

Revert the change for now, we'll redo it for the next merge window
after refactoring the code to better split the file system vs ioctl
callers and cleaning up a few other loose ends.

273960b8f3 bcachefs: time_stats: split stats-with-quantiles into a separate structure 
Currently, struct time_stats has the optional ability to quantize the
information that it collects.  This is /probably/ useful for callers who
want to see quantized information, but it more than doubles the size of
the structure from 224 bytes to 464.  For users who don't care about
that (e.g. upcoming xfs patches) and want to avoid wasting 240 bytes per
counter, split the two into separate pieces.

4b4f0876ab bcachefs: mean_and_variance: put struct mean_and_variance_weighted on a diet 
The only caller of this code (time_stats) always knows the weights and
whether or not any information has been collected.  Pass this
information into the mean and variance code so that it doesn't have to
store that information.  This reduces the structure size from 24 to 16
bytes, which shrinks each time_stats counter to 192 bytes from 208.

3e48999816 bcachefs: Prefer struct_size over open coded arithmetic 
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1][2].

As the "op" variable is a pointer to "struct promote_op" and this
structure ends in a flexible array:

struct promote_op {
	[...]
	struct bio_vec bi_inline_vecs[];
};

and the "t" variable is a pointer to "struct journal_seq_blacklist_table"
and this structure also ends in a flexible array:

struct journal_seq_blacklist_table {
	[...]
	struct journal_seq_blacklist_table_entry {
		u64		start;
		u64		end;
		bool		dirty;
	}			entries[];
};

the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the argument "size + size * count" in the
kzalloc() functions.

This way, the code is more readable and safer.

c42006458b bcachefs: Check for writing superblocks with nonsense member seq fields 
We're seeing some unmountable filesystems due to split brain detection
going awry; it seems we somehow wrote out superblocks where we updated
the superblock seq without updating any member seq fields.

A given device's superblock should always have the main seq equal to
it's member seq field, so this is easy to check for.

this code originally used the page allocator directly, but most code

4k is also on the large side for typical usage, 512 bytes is a better

ada02c207c bcachefs: fix lost journal buf wakeup due to improved pipelining 
The journal_write_done() handler was reworked into a loop in commit
746a33c96b7a ("bcachefs: better journal pipelining"). As part of this,
the journal buffer wake was factored into a post-loop branch that
executes if at least one journal buffer has completed.

The journal buffer processing loop iterates on the journal buffer
pointer, however. This means that w refers to the last buffer processed
by the loop, which may or may not be done. This also means that if
multiple buffers are processed by the loop, only the last is awoken.
This lost wakeup behavior has lead to stalling problems in various CI
and fstests, such as generic/703.

Lift the wake into the loop so each done buffer sees a wake call as
it is processed.

7e64c86cdc bcachefs: Buffered write path now can avoid the inode lock 
Non append, non extending buffered writes can now avoid taking the inode
lock.

To ensure atomicity of writes w.r.t. other writes, we lock every folio
that we'll be writing to, and if this fails we fall back to taking the
inode lock.

Extensive comments are provided as to corner cases.

79162e829b bcachefs: fix the error code when mounting with incorrect options. 
When mount with incorrect options such as:
"mount -t bcachefs -o errors=back /dev/loop1 /mnt/bcachefs/".
It rebacks the error "mount: /mnt/bcachefs: permission denied."
 cause bch2_parse_mount_opts returns -1 and bch2_mount throws
it up. This is unreasonable.

The real error message should be like this:
"mount: /mnt/bcachefs: wrong fs type, bad option, bad
superblock on /dev/loop1, missing codepage or helper program,
or other error."

Adding three private error codes for mounting error. Here are:
  - BCH_ERR_mount_option as the parent class for option error.
  - BCH_ERR_option_name represents the invalid option name.
  - BCH_ERR_option_value represents the invalid option value.
