This BUG is the VM_BUG_ON(!in_atomic() && !irqs_disabled()) assertion in
folio_ref_try_add_rcu() for non-SMP kernel.

The process_vm_readv() calls GUP to pin the THP. An optimization for
pinning THP instroduced by commit 57edfcfd34 ("mm/gup: accelerate thp
gup even for "pages != NULL"") calls try_grab_folio() to pin the THP,
but try_grab_folio() is supposed to be called in atomic context for
non-SMP kernel, for example, irq disabled or preemption disabled, due to
the optimization introduced by commit e286781d5f ("mm: speculative
page references").

The commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") is not actually the root cause although it was bisected to.
It just makes the problem exposed more likely.

The follow up discussion suggested the optimization for non-SMP kernel
may be out-dated and not worth it anymore [1].  So removing the
optimization to silence the BUG.

However calling try_grab_folio() in GUP slow path actually is
unnecessary, so the following patch will clean this up.

Masahiro Yamada 170ce55eff ARM: 9324/1: fix get_user() broken with veneer
commit 24d3ba0a7b44c1617c27f5045eecc4f34752ab03 upstream.

The 32-bit ARM kernel stops working if the kernel grows to the point
where veneers for __get_user_* are created.

AAPCS32 [1] states, "Register r12 (IP) may be used by a linker as a
scratch register between a routine and any subroutine it calls. It
can also be used within a routine to hold intermediate values between
subroutine calls."

However, bl instructions buried within the inline asm are unpredictable
for compilers; hence, "ip" must be added to the clobber list.

This becomes critical when veneers for __get_user_* are created because
veneers use the ip register since commit 02e541db05 ("ARM: 8323/1:
force linker to use PIC veneers").

Steve French c15682ed16 cifs: fix noisy message on copy_file_range
commit ae4ccca47195332c69176b8615c5ee17efd30c46 upstream.

There are common cases where copy_file_range can noisily
log "source and target of copy not on same server"
e.g. the mv command across mounts to two different server's shares.
Change this to informational rather than logging as an error.

A followon patch will add dynamic trace points e.g. for
cifs_file_copychunk_range

The recent fix introduced a reverse selection of
CONFIG_SERIAL_MULTI_INSTANTIATE, but its condition isn't always met.
Use a weak reverse selection to suggest the config for avoiding such
inconsistencies, instead.

John Hubbard 54f137ee27 selftests/vDSO: fix clang build errors and warnings
[ Upstream commit 73810cd45b99c6c418e1c6a487b52c1e74edb20d ]

When building with clang, via:

    make LLVM=1 -C tools/testing/selftests

...there are several warnings, and an error. This fixes all of those and
allows these tests to run and pass.

1. Fix linker error (undefined reference to memcpy) by providing a local
   version of memcpy.

2. clang complains about using this form:

    if (g = h & 0xf0000000)

...so factor out the assignment into a separate step.

3. The code is passing a signed const char* to elf_hash(), which expects
   a const unsigned char *. There are several callers, so fix this at
   the source by allowing the function to accept a signed argument, and
   then converting to unsigned operations, once inside the function.

4. clang doesn't have __attribute__((externally_visible)) and generates
   a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem
   to require that attribute in order to build, run and pass tests here,
   so remove it.

Uwe Kleine-König bd3ca9bb56 spi: imx: Don't expect DMA for i.MX{25,35,50,51,53} cspi devices
[ Upstream commit ce1dac560a74220f2e53845ec0723b562288aed4 ]

While in commit 2dd33f9cec ("spi: imx: support DMA for imx35") it was
claimed that DMA works on i.MX25, i.MX31 and i.MX35 the respective
device trees don't add DMA channels. The Reference manuals of i.MX31 and
i.MX25 also don't mention the CSPI core being DMA capable. (I didn't
check the others.)

Since commit e267a5b3ec59 ("spi: spi-imx: Use dev_err_probe for failed
DMA channel requests") this results in an error message

	spi_imx 43fa4000.spi: error -ENODEV: can't get the TX DMA channel!

during boot. However that isn't fatal and the driver gets loaded just
fine, just without using DMA.

Christian Brauner c09e07857c fs: better handle deep ancestor chains in is_subdir()
[ Upstream commit 391b59b045004d5b985d033263ccba3e941a7740 ]

Jan reported that 'cd ..' may take a long time in deep directory
hierarchies under a bind-mount. If concurrent renames happen it is
possible to livelock in is_subdir() because it will keep retrying.

Change is_subdir() from simply retrying over and over to retry once and
then acquire the rename lock to handle deep ancestor chains better. The
list of alternatives to this approach were less then pleasant. Change
the scope of rcu lock to cover the whole walk while at it.

A big thanks to Jan and Linus. Both Jan and Linus had proposed
effectively the same thing just that one version ended up being slightly
more elegant.

[ Upstream commit 9b32b063be1001e322c5f6e01f2a649636947851 ]

Sometimes, the on-disk metadata might be invalid due to user
interrupts, storage failures, or other unknown causes.

In that case, z_erofs_map_blocks_iter() may still return a valid
m_llen while other fields remain invalid (e.g., m_plen can be 0).

Due to the return value of z_erofs_scan_folio() in some path will
be ignored on purpose, the following z_erofs_scan_folio() could
then use the invalid value by accident.

Let's reset m_llen to 0 to prevent this.

[ Upstream commit 89e856e124f9ae548572c56b1b70c2255705f8fe ]

The problem occurs between the system call to close the sock and hci_rx_work,
where the former releases the sock and the latter accesses it without lock protection.

           CPU0                       CPU1
           ----                       ----
           sock_close                 hci_rx_work
	   l2cap_sock_release         hci_acldata_packet
	   l2cap_sock_kill            l2cap_recv_frame
	   sk_free                    l2cap_conless_channel
	                              l2cap_sock_recv_cb

If hci_rx_work processes the data that needs to be received before the sock is
closed, then everything is normal; Otherwise, the work thread may access the
released sock when receiving data.

Add a chan mutex in the rx callback of the sock to achieve synchronization between
the sock release and recv cb.

Sock is dead, so set chan data to NULL, avoid others use invalid sock pointer.

syzbot is reporting that calling hci_release_dev() from hci_error_reset()

queued into hdev->req_workqueue are no longer running by the moment

       destroy_workqueue(hdev->workqueue);
       destroy_workqueue(hdev->req_workqueue);

are called from hci_release_dev().

Call cancel_work_sync() on these work items from hci_unregister_dev()
as soon as hdev->list is removed from hci_dev_list.

Shengjiu Wang c305a708bc ALSA: dmaengine_pcm: terminate dmaengine before synchronize
[ Upstream commit 6a7db25aad8ce6512b366d2ce1d0e60bac00a09d ]

When dmaengine supports pause function, in suspend state,
dmaengine_pause() is called instead of dmaengine_terminate_async(),

In end of playback stream, the runtime->state will go to
SNDRV_PCM_STATE_DRAINING, if system suspend & resume happen
at this time, application will not resume playback stream, the
stream will be closed directly, the dmaengine_terminate_async()
will not be called before the dmaengine_synchronize(), which
violates the call sequence for dmaengine_synchronize().

This behavior also happens for capture streams, but there is no
SNDRV_PCM_STATE_DRAINING state for capture. So use
dmaengine_tx_status() to check the DMA status if the status is
DMA_PAUSED, then call dmaengine_terminate_async() to terminate
dmaengine before dmaengine_synchronize().

Nick Child 267c61c4af ibmvnic: Add tx check to prevent skb leak
[ Upstream commit 0983d288caf984de0202c66641577b739caad561 ]

Below is a summary of how the driver stores a reference to an skb during
transmit:
    tx_buff[free_map[consumer_index]]->skb = new_skb;
    free_map[consumer_index] = IBMVNIC_INVALID_MAP;
    consumer_index ++;
Where variable data looks like this:
    free_map == [4, IBMVNIC_INVALID_MAP, IBMVNIC_INVALID_MAP, 0, 3]
                                               	consumer_index^
    tx_buff == [skb=null, skb=<ptr>, skb=<ptr>, skb=null, skb=null]

The driver has checks to ensure that free_map[consumer_index] pointed to
a valid index but there was no check to ensure that this index pointed
to an unused/null skb address. So, if, by some chance, our free_map and
tx_buff lists become out of sync then we were previously risking an
skb memory leak. This could then cause tcp congestion control to stop
sending packets, eventually leading to ETIMEDOUT.

Therefore, add a conditional to ensure that the skb address is null. If
not then warn the user (because this is still a bug that should be
patched) and free the old pointer to prevent memleak/tcp problems.

Filipe Manana f88aeff5a1 btrfs: qgroup: fix quota root leak after quota disable failure
[ Upstream commit a7e4c6a3031c74078dba7fa36239d0f4fe476c53 ]

If during the quota disable we fail when cleaning the quota tree or when
deleting the root from the root tree, we jump to the 'out' label without
ever dropping the reference on the quota root, resulting in a leak of the
root since fs_info->quota_root is no longer pointing to the root (we have
set it to NULL just before those steps).

Fix this by always doing a btrfs_put_root() call under the 'out' label.
This is a problem that exists since qgroups were first added in 2012 by
commit bed92eae26 ("Btrfs: qgroup implementation and prototypes"), but
back then we missed a kfree on the quota root and free_extent_buffer()
calls on its root and commit root nodes, since back then roots were not
yet reference counted.

Armin Wolf 9f25bd7013 platform/x86: lg-laptop: Use ACPI device handle when evaluating WMAB/WMBB
[ Upstream commit b27ea279556121b54d3f45d0529706cf100cdb3a ]

On the LG Gram 16Z90S, the WMAB and WMBB ACPI methods are not mapped
under \XINI, but instead are mapped under \_SB.XINI.

The reason for this is that the LGEX0820 ACPI device used by this
driver is mapped at \_SB.XINI, so the ACPI methods where moved as well
to appear below the LGEX0820 ACPI device.

Fix this by using the ACPI handle from the ACPI device when evaluating
both methods.

Peter Ujfalusi e18dfef2b5 ASoC: SOF: sof-audio: Skip unprepare for in-use widgets on error rollback
[ Upstream commit 6f2a43e3d14f6e31a3b041a1043195d02c54d615 ]

If the ipc_prepare() callback fails for a module instance, on error rewind
we must skip the ipc_unprepare() call for ones that has positive use count.

The positive use count means that the module instance is in active use, it
cannot be unprepared.

The issue affects capture direction paths with branches (single dai with
multiple PCMs), the affected widgets are in the shared part of the paths.

Primoz Fiser 9d944d4aa9 ASoC: ti: omap-hdmi: Fix too long driver name
[ Upstream commit 524d3f126362b6033e92cbe107ae2158d7fbff94 ]

Set driver name to "HDMI". This simplifies the code and gets rid of
the following error messages:

  ASoC: driver name too long 'HDMI 58040000.encoder' -> 'HDMI_58040000_e'
