The SPIE register contains counts for the TX FIFO so any time the irq
handler was invoked we would attempt to process the RX/TX fifos. Use the
SPIM value to mask the events so that we only process interrupts that
were expected.

The fix is straightforward, just adding an 'inline' to make this a

Following the path in pm_runtime_put_sync_suspend() from
psci_enter_domain_idle_state(), it seems like we end up using the RCU.
Therefore, let's simply silence the splat by informing the RCU about it
with RCU_NONIDLE.
Note that, this is a temporary solution. Instead we should strive to avoid
using RCU_NONIDLE (and similar), but rather push rcu_idle_enter|exit()
further down, closer to the arch specific code. However, as the CPU PM
notifiers are also using the RCU, additional rework is needed.

We found a Mic detection issue on many Lenovo laptops, those laptops
belong to differnt models and they have different audio design like
internal mic connects to the codec or PCH, they all have this problem,
the problem is if plugging a headset before powerup/reboot the
machine, after booting up, the headphone could be detected but Mic
couldn't. If we plug out and plug in the headset, both headphone and
Mic could be detected then.
Through debugging we found the codec on those laptops are same, it is
alc257, and if we don't disable the 3k pulldown in alc256_shutup(),
the issue will be fixed. So far there is no pop noise or power
consumption regression on those laptops after this change.

Returning "unknown" as a temperature value violates the hwmon interface
rules. Appropriate error codes should be returned via device_attribute
show instead. These will ultimately be propagated to the user via the
file system interface.
In addition to the corrected error handling, it is an even better idea to
not present the sensor in sysfs at all if it is known that the read will
definitely fail. Given that temp1_input is currently the only sensor
reported, ensure no hwmon registration if TEMP_MONITOR_QUERY is not
supported or if it will fail due to access permissions. Something smarter
may be needed if and when other sensors are added.

KVM: s390: add documentation for KVM_CAP_S390_DIAG318
diag318 code was merged in 5.9-rc1, let us add some
missing documentation
The commit 0f99022210 ("KVM: Check the allocation of pv cpu mask") we
have in 5.9-rc5 has two issue:
1) Compilation fails for !CONFIG_SMP, see:
https://bugzilla.kernel.org/show_bug.cgi?id=209285
2) This commit completely disables PV TLB flush, see
https://lore.kernel.org/kvm/87y2lrnnyf.fsf@vitty.brq.redhat.com/
The allocation problem is likely a theoretical one, if we don't
have memory that early in boot process we're likely doomed anyway.
Let's solve it properly later.
This reverts commit 0f99022210.

When calculating ancestor_size with IPv6 enabled, simply using
sizeof(struct ipv6_pinfo) doesn't account for extra bytes needed for
alignment in the struct sctp6_sock. On x86, there aren't any extra
bytes, but on ARM the ipv6_pinfo structure is aligned on an 8-byte
boundary so there were 4 pad bytes that were omitted from the
ancestor_size calculation. This would lead to corruption of the
pd_lobby pointers, causing an oops when trying to free the sctp
structure on socket close.

* A fix for a lockdep issue to avoid an asserting triggering during early boot.
There shouldn't be any incorrect behavior as the system isn't concurrent at
the time.
* The addition of a missing fence when installing early fixmap mappings.
* A corretion to the K210 device tree's interrupt map.
* A fix for M-mode timer handling on the K210.
I know it's a it of an odd time, so if these don't make rc6 it's not a big
deal, but I thought I'd just send it out now rather that waiting as these are
ready to go.
