There are reports that the pagetable walker cache coherency is not a
given across the spectrum of SDM845/850 devices, leading to lock-ups
and resets. It works fine on some devices (like the Dragonboard 845c,
but not so much on the Lenovo Yoga C630).
This unfortunately looks like a fluke in firmware development, where
likely somewhere in the vast hypervisor stack, a change to accommodate
for this was only introduced after the initial software release (which
often serves as a baseline for products).
Revert the change to avoid additional guesswork around crashes.
This reverts commit 6b31a9744b8726c69bb0af290f8475a368a4b805.

ASUS VivoBook 15 with SSID 1043:1460 took an incorrect quirk via the
pin pattern matching for ASUS (ALC256_FIXUP_ASUS_MIC), resulting in
the two built-in mic pins (0x13 and 0x1b). This had worked without
problems casually in the past because the right pin (0x1b) was picked
up as the primary device. But since we fixed the pin enumeration for
other bugs, the bogus one (0x13) is picked up as the primary device,
hence the bug surfaced now.
For addressing the regression, this patch explicitly specifies the
quirk entry with ALC256_FIXUP_ASUS_MIC_NO_PRESENCE, which sets up only
the headset mic pin.

When SPI is used for control, the driver must hold the SPI bus lock
while issuing the sequence of writes to perform a soft reset.
>From the time the driver writes the SYSTEM_RESET command until the
driver does a write to terminate the reset, there must not be any
activity on the SPI bus lines. If there is any SPI activity during the
soft-reset, another soft-reset will be triggered. The state of the SPI
chip select is irrelevant.
A repeated soft-reset does not in itself cause any problems, and it is
not an infinite loop. The problem is a race between these resets and
the driver polling for boot completion. There is a time window between
soft resets where the driver could read HALO_STATE as 2 (fully booted)
while the chip is actually soft-resetting. Although this window is
small, it is long enough that it is possible to hit it in normal
operation.
To prevent this race and ensure the chip really is fully booted, the
driver calls spi_bus_lock() to prevent other activity while resetting.
It then issues the SYSTEM_RESET mailbox command. After allowing
sufficient time for reset to take effect, the driver issues a PING
mailbox command, which will force completion of the full soft-reset
sequence. The SPI bus lock can then be released. The mailbox is
checked for any boot or wakeup response from the firmware, before the
value in HALO_STATE will be trusted.
This does not affect SoundWire or I2C control.

Change calls to async regmap write functions to use the normal
blocking writes so that the cs35l56 driver can use spi_bus_lock() to
gain exclusive access to the SPI bus.
As this is part of a fix, it makes only the minimal change to swap the
functions to the blocking equivalents. There's no need to risk
reworking the buffer allocation logic that is now partially redundant.
The async writes are a 12-year-old workaround for inefficiency of
synchronous writes in the SPI subsystem. The SPI subsystem has since
been changed to avoid the overheads, so this workaround should not be
necessary.
The cs35l56 driver needs to use spi_bus_lock() prevent bus activity
while it is soft-resetting the cs35l56. But spi_bus_lock() is
incompatible with spi_async() calls, which will fail with -EBUSY.

The buffer cache keeps a bt_io_count per-CPU counter to track all
in-flight I/O, which is used to ensure no I/O is in flight when
unmounting the file system.
For most I/O we already keep track of inflight I/O at higher levels:
- for synchronous I/O (xfs_buf_read/xfs_bwrite/xfs_buf_delwri_submit),
the caller has a reference and waits for I/O completions using
xfs_buf_iowait
- for xfs_buf_delwri_submit_nowait the only caller (AIL writeback)
tracks the log items that the buffer attached to
This only leaves only xfs_buf_readahead_map as a submitter of
asynchronous I/O that is not tracked by anything else. Replace the
bt_io_count per-cpu counter with a more specific bt_readahead_count
counter only tracking readahead I/O. This allows to simply increment
it when submitting readahead I/O and decrementing it when it completed,
and thus simplify xfs_buf_rele and remove the needed for the
XBF_NO_IOACCT flags and the XFS_BSTATE_IN_FLIGHT buffer state.

Since thermal_of_should_bind() terminates the loop after processing
the first child found in cooling-maps, it will never match more than
one cdev to a given trip point which is incorrect, as there may be
cooling-maps associating one trip point with multiple cooling devices.
Address this by letting the loop continue until either all
children have been processed or a matching one has been found.
To avoid adding conditionals or goto statements, put the loop in
question into a separate function and make that function return
right away after finding a matching cooling-maps entry.

When an Icelake or Sapphire Rapids CPU isn't providing the maximum and
critical thresholds for particular DIMM the driver should return an
error to the userspace instead of giving it stale (best case) or wrong
(the structure contains all zeros after kzalloc() call) data.
The issue can be reproduced by binding the peci driver while the host is
fully booted and idle, this makes PECI interaction unreliable enough.

Pull RISC-V fixes from Palmer Dabbelt:
- A fix for cacheinfo DT probing to avoid reading non-boolean
properties as booleans.
- A fix for cpufeature to use bitmap_equal() instead of memcmp(), so
unused bits are ignored.
- Fixes for cmpxchg and futex cmpxchg that properly encode the sign
extension requirements on inline asm, which results in spurious
successes. This manifests in at least inode_set_ctime_current, but is
likely just a disaster waiting to happen.
- A fix for the rseq selftests, which was using an invalid constraint.
- A pair of fixes for signal frame size handling:
- We were reserving space for an extra empty extension context
header on systems with extended signal context, thus resulting in
unnecessarily large allocations.
- We weren't properly checking for available extensions before
calculating the signal stack size, which resulted in undersized
stack allocations on some systems (at least those with T-Head
custom vectors).
Also, we've added Alex as a reviewer. He's been helping out a ton
lately, thanks!

The PCI P2PDMA code will register the CMB block to the memory
hot-plugging subsystem, which have an alignment requirement. Memory
blocks that do not satisfy this alignment requirement (usually 2MB) will
lead to a WARNING from memory hotplugging.
Verify the CMB block's address and size against the alignment and only
try to send CMB blocks compatible with it to prevent this warning.
Tested on Intel DC D4502 SSD, which has a 512K CMB block that is too

The legacy ioctl path does not have support for extended attributes.
So we issue a GET to fetch the current settings from the driver,
in an attempt to keep them unchanged. HDS is a bit "special" as
the GET only returns on/off while the SET takes a "ternary" argument
(on/off/default). If the driver was in the "default" setting -
executing the ioctl path binds it to on or off, even tho the user
did not intend to change HDS config.
Factor the relevant logic out of the netlink code and reuse it.

Currently we treat EFAULT from hmm_range_fault() as a non-fatal error
when called from xe_vm_userptr_pin() with the idea that we want to avoid
killing the entire vm and chucking an error, under the assumption that
the user just did an unmap or something, and has no intention of
actually touching that memory from the GPU. At this point we have
already zapped the PTEs so any access should generate a page fault, and
if the pin fails there also it will then become fatal.
However it looks like it's possible for the userptr vma to still be on
the rebind list in preempt_rebind_work_func(), if we had to retry the
pin again due to something happening in the caller before we did the
rebind step, but in the meantime needing to re-validate the userptr and
this time hitting the EFAULT.
This explains an internal user report of hitting:

On error restore anything still on the pin_list back to the invalidation
list on error. For the actual pin, so long as the vma is tracked on
either list it should get picked up on the next pin, however it looks
possible for the vma to get nuked but still be present on this per vm
pin_list leading to corruption. An alternative might be then to instead
just remove the link when destroying the vma.
v2:
- Also add some asserts.
- Keep the overzealous locking so that we are consistent with the docs;
updating the docs and related bits will be done as a follow up.

The cause is that zero pfn is set to the PTE without increasing the RSS
count in mfill_atomic_pte_zeropage() and the refcount of zero folio does
not increase accordingly. Then, the operation on the same pfn is performed
in uprobe_write_opcode()->__replace_page() to unconditional decrease the
RSS count and old_folio's refcount.
Therefore, two bugs are introduced:
1. The RSS count is incorrect, when process exit, the check_mm() report
error "Bad rss-count".
2. The reserved folio (zero folio) is freed when folio->refcount is zero,
then free_pages_prepare->free_page_is_bad() report error
"Bad page state".
There is more, the following warning could also theoretically be triggered:
__replace_page()
-> ...
-> folio_remove_rmap_pte()
-> VM_WARN_ON_FOLIO(is_zero_folio(folio), folio)
Considering that uprobe hit on the zero folio is a very rare case, just
reject zero old folio immediately after get_user_page_vma_remote().

The sorting of VMAs by size in commit 7d442a33bfe8 ("binfmt_elf: Dump
smaller VMAs first in ELF cores") breaks elfutils[1]. Instead, sort
based on the setting of the new sysctl, core_sort_vma, which defaults
to 0, no sorting.

Some tools like KGraphViewer interpret the "ON" nodes not having an
explicitly set fill colour as them being entirely black, which obscures
the text on them and looks funny. In fact, I thought they were off for
the longest time. Comparing to the output of the `dot` tool, I assume
they are supposed to be white.
Instead of speclawyering over who's in the wrong and must immediately
atone for their wickedness at the altar of RFC2119, just be explicit
about it, set the fillcolor to white, and nobody gets confused.

If stream names of DAI driver are duplicated there'll be warnings when
machine driver tries to add widgets on a route:
[ 8.831335] fsl-asoc-card sound-wm8960: ASoC: sink widget CPU-Playback overwritten
[ 8.839917] fsl-asoc-card sound-wm8960: ASoC: source widget CPU-Capture overwritten
Use different stream names to avoid such warnings.
DAI names in AUDMIX are also updated accordingly.
