"These fix three issues in the system-wide suspend and hibernation area
related to PCI device PM handling by suspend-to-idle, device wakeup
optimizations and arbitrary differences between suspend and
hiberantion.
Specifics:
- Modify the PCI bus type's PM code to avoid putting devices left by
their drivers in D0 on purpose during suspend to idle into
low-power states as doing that may confuse the system resume
callbacks of the drivers in question (Rafael Wysocki).
- Avoid checking ACPI wakeup configuration during system-wide suspend
for suspended devices that do not use ACPI-based wakeup to allow
them to stay in suspend more often (Rafael Wysocki).
- The last phase of hibernation is analogous to system-wide suspend
also because on platforms with ACPI it passes control to the
platform firmware to complete the transision, so make it indicate
that by calling pm_set_suspend_via_firmware() to allow the drivers
that care about this to do the right thing (Rafael Wysocki)"

The ram pstore backend has always had the crash dumper frontend enabled
unconditionally. However, it was possible to effectively disable it
by setting a record_size=0. All the machinery would run (storing dumps
to the temporary crash buffer), but 0 bytes would ultimately get stored
due to there being no przs allocated for dumps. Commit 89d328f637b9
("pstore/ram: Correctly calculate usable PRZ bytes"), however, assumed
that there would always be at least one allocated dprz for calculating
the size of the temporary crash buffer. This was, of course, not the
case when record_size=0, and would lead to a NULL deref trying to find
the dprz buffer size:
BUG: unable to handle kernel NULL pointer dereference at (null)
...
IP: ramoops_probe+0x285/0x37e (fs/pstore/ram.c:808)
cxt->pstore.bufsize = cxt->dprzs[0]->buffer_size;
Instead, we need to only enable the frontends based on the success of the
prz initialization and only take the needed actions when those zones are
available. (This also fixes a possible error in detecting if the ftrace
frontend should be enabled.)

In order for kernel to capture each denormalized output, the UDF
trapping enable bit is always raised in $fpcsr. Because underflow case will
issue not an underflow exception but also an inexact exception, it causes
that the IEX, IEX cumulative exception, flag in $fpcsr to be raised in each
denormalized output handling. To make the emulation transparent to the
user, the emulator needs to clear the IEX flag in $fpcsr if the result is a
denormalized number. However, if the IEX flag has been raised before this
floating point emulation, this cleanup may be incorrect. To avoid the IEX
flags in $fpcsr be raised in each denormalized output handling, the IEX
trap shall be always enabled.

"The fixes are still trickling in for arm64, but the only really
significant one here is actually fixing a regression in the botched
module relocation range checking merged for -rc2.
Hopefully we've nailed it this time.
- Fix implementation of our set_personality() system call, which
wasn't being wrapped properly
- Fix system call function types to keep CFI happy
- Fix siginfo layout when delivering SIGKILL after a kernel fault
- Really fix module relocation range checking"

Pull btrfs fixes from David Sterba:
"A few more fixes for bugs reported by users, fuzzing tools and
regressions:
- fix crashes in relocation:
+ resuming interrupted balance operation does not properly clean
up orphan trees
+ with enabled qgroups, resuming needs to be more careful about
block groups due to limited context when updating qgroups
- fsync and logging fixes found by fuzzing
- incremental send fixes for no-holes and clone
- fix spin lock type used in timer function for zstd"

Pull sound fixes from Takashi Iwai:
"No big surprises here, just a few device-specific fixes.
HD-audio received several fixes for Acer, Dell, Huawei and other
laptops as well as the workaround for the new Intel chipset. One
significant one-liner fix is the disablement of the node-power saving
on Realtek codecs, which may potentially cover annoying bugs like the
background noises or click noises on many devices.
Other than that, a fix for FireWire bit definitions, and another fix
for LINE6 USB audio bug that was discovered by syzkaller"

drm/imx: ipuv3-plane: fix frame rate regression on non-plus i.MX6Q
Fix a regression introduced by 70e8a0c71e9 ("drm/imx: ipuv3-plane: add
function to query atomic update status") that halves the frame rate on
non-plus i.MX6Q, because the pending check always returns "pending"
even if an update is actually applied.

TCP zerocopy takes a uarg reference for every skb, plus one for the
tcp_sendmsg_locked datapath temporarily, to avoid reaching refcnt zero
as it builds, sends and frees skbs inside its inner loop.
UDP and RAW zerocopy do not send inside the inner loop so do not need
the extra sock_zerocopy_get + sock_zerocopy_put pair. Commit
52900d22288ed ("udp: elide zerocopy operation in hot path") introduced
extra_uref to pass the initial reference taken in sock_zerocopy_alloc
to the first generated skb.
But, sock_zerocopy_realloc takes this extra reference at the start of
every call. With MSG_MORE, no new skb may be generated to attach the
extra_uref to, so refcnt is incorrectly 2 with only one skb.
Do not take the extra ref if uarg && !tcp, which implies MSG_MORE.
Update extra_uref accordingly.
This conditional assignment triggers a false positive may be used
uninitialized warning, so have to initialize extra_uref at define.
