The existing use of match_string() caused it to reject 'echo foo' due
to the implicitly appended newline, which was somewhat ergonomically
awkward and inconsistent with typical sysfs behavior. Using the
__sysfs_* variant instead provides more convenient and consistent
linefeed-agnostic behavior.

provided a fix for the Zen2 VZEROUPPER data corruption bug affecting
a range of CPU models, but the AMD Custom APU 0405 found on SteamDeck
was not listed, although it is clearly affected by the vulnerability.
Add this CPU variant to the Zenbleed erratum list, in order to
unconditionally enable the fallback fix until a proper microcode update
is available.

"These fix an amd-pstate cpufreq driver issues and recently introduced
hibernation-related breakage.
Specifics:
- Make amd-pstate use device_attributes as expected by the CPU root
kobject (Thomas Weißschuh)
- Restore the previous behavior of resume_store() when hibernation is
not available which is to return the full number of bytes that were
to be written by user space (Vlastimil Babka)"

cpufreq: amd-pstate: fix global sysfs attribute type
PM: hibernate: fix resume_store() return value when hibernation not available
We want to fix the serial core port DEVNAME to use a port id of the
hardware specific controller port instance instead of the port->line.
For example, the 8250 driver sets up a number of serial8250 ports
initially that can be inherited by the hardware specific driver. At that
the port->line no longer decribes the port's relation to the serial core
controller instance.
Let's fix the issue by assigning port->port_id for each serial core
controller port instance.

The port lock is not always held when calling serial8250_clear_IER().
When an oops is in progress, the lock is tried to be taken and when it
is not, a warning is issued:

Therefore, remove the annotation as it doesn't hold for all invocations.
The other option would be to make the lockdep test conditional on
'oops_in_progress' or pass 'locked' from serial8250_console_write(). I
don't think, that is worth it.

In commit 9b9c8195f3 ("tty: n_gsm: fix UAF in gsm_cleanup_mux"), the UAF
problem is not completely fixed. There is a race condition in
gsm_cleanup_mux(), which caused this UAF.
The UAF problem is triggered by the following race:
task[5046] task[5054]
----------------------- -----------------------
gsm_cleanup_mux();
dlci = gsm->dlci[0];
mutex_lock(&gsm->mutex);
gsm_cleanup_mux();
dlci = gsm->dlci[0]; //Didn't take the lock
gsm_dlci_release(gsm->dlci[i]);
gsm->dlci[i] = NULL;
mutex_unlock(&gsm->mutex);
mutex_lock(&gsm->mutex);
dlci->dead = true; //UAF
Fix it by assigning values after mutex_lock().

Enabling tmpfs "direct IO" exposes it to invalidate_inode_pages2_range(),
which when swapping can hit the VM_BUG_ON_FOLIO(!folio_contains()): the
folio has been moved from page cache to swap cache (with folio->mapping
reset to NULL), but the folio_index() embedded in folio_contains() sees
swapcache, and so returns the swapcache_index() - whereas folio->index
would be the right one to check against the index from mapping's xarray.
There are different ways to fix this, but my preference is just to order
the checks in invalidate_inode_pages2_range() the same way that they are
in __filemap_get_folio() and find_lock_entries() and filemap_fault():
check folio->mapping before folio_contains().

Depending upon your philosophical viewpoint, either tmpfs always does
direct IO, or it cannot ever do direct IO; but whichever, if tmpfs is to
stand in for a more sophisticated filesystem, it can be helpful for tmpfs
to support O_DIRECT. So, give tmpfs a shmem_file_open() method, to set
the FMODE_CAN_ODIRECT flag: then unchanged shmem_file_read_iter() and new
shmem_file_write_iter() do the work (without any shmem_direct_IO() stub).
Perhaps later, once the direct_IO method has been eliminated from all
filesystems, generic_file_write_iter() will be such that tmpfs can again
use it, even for O_DIRECT.
xfstests auto generic which were not run on tmpfs before but now pass:
036 091 113 125 130 133 135 198 207 208 209 210 211 212 214 226 239 263

with no new failures.
LTP dio tests which were not run on tmpfs before but now pass:
dio01 through dio30, except for dio04 and dio10, which fail because
tmpfs dio read and write allow odd count: tmpfs could be made stricter,
but would that be an improvement?

Just like get_tree_bdev needs to drop s_umount when opening the main

It might be preferable to just drop s_umount over ->fill_super entirely,
but that will require a fairly massive audit first, so we'll do the easy

fs_mark_dead currently uses get_super to find the superblock for the
block device that is going away. This means it is limited to the
main device stored in sb->s_dev, leading to a lot of code duplication
for file systems that can use multiple block devices.
Now that the holder for all block devices used by file systems is set
to the super_block, we can instead look at that holder and then check
if the file system is born and active, so do that instead.

The VFS always uses coarse-grained timestamps when updating the ctime
and mtime after a change. This has the benefit of allowing filesystems
to optimize away a lot metadata updates, down to around 1 per jiffy,
even when a file is under heavy writes.
Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide to invalidate the cache. Even with NFSv4, a lot of
exported filesystems don't properly support a change attribute and are
subject to the same problems with timestamp granularity. Other
applications have similar issues with timestamps (e.g backup
applications).
If we were to always use fine-grained timestamps, that would improve the
situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.
What we need is a way to only use fine-grained timestamps when they are
being actively queried.
POSIX generally mandates that when the the mtime changes, the ctime must
also change. The kernel always stores normalized ctime values, so only
the first 30 bits of the tv_nsec field are ever used.
Use the 31st bit of the ctime tv_nsec field to indicate that something
has queried the inode for the mtime or ctime. When this flag is set,
on the next mtime or ctime update, the kernel will fetch a fine-grained
timestamp instead of the usual coarse-grained one.
Filesytems can opt into this behavior by setting the FS_MGTIME flag in
the fstype. Filesystems that don't set this flag will continue to use
coarse-grained timestamps.
Later patches will convert individual filesystems to use the new
infrastructure.
