On some platforms we need to trigger an extra async flip with
the async flip bit disabled, and then wait for the next vblank
until the async flip bit off state will actually latch.
Currently the w/a is just open coded for skl+ universal planes.
Instead of doing that lets reuse the .async_flip() hook for this
purpose since it needs to write the exact same set of registers.
In order to do this we'll just have the caller pass in the state
of the async flip bit explicitly.

Set up the async flip PLANE_CTL bit directly in the
.async_flip() hook. Neither .update_plane() nor .disable_plane()
ever need to set this so having it done by skl_plane_ctl_crtc()
is rather pointless.

Only assign the plane->async_flip() vfunc when the plane supports
async flips. For now we keep this artificially limited to the primary
plane since thats the only thing the legacy page flip uapi can target
and there is no async flip support in the atomic uapi yet.

On x86 scale invariace tends to be disabled during resume from
suspend-to-RAM, because the MPERF or APERF MSR values are not as
expected then due to updates taking place after the platform
firmware has been invoked to complete the suspend transition.
That, of course, is not desirable, especially if the schedutil
scaling governor is in use, because the lack of scale invariance
causes it to be less reliable.
To counter that effect, modify init_freq_invariance() to register
a syscore_ops object for scale invariance with the ->resume callback
pointing to init_counter_refs() which will run on the CPU starting
the resume transition (the other CPUs will be taken care of the
"online" operations taking place later).

After hibernation, HDA controller can't be runtime-suspended after
commit 215a22ed31a1 ("ALSA: hda: Refactor codjc PM to use
direct-complete optimization"), which enables direct-complete for HDA
codec.
The HDA codec driver didn't expect direct-complete will be disabled
after it returns a positive value from prepare() callback. However,
there are some places that PM core can disable direct-complete. For
instance, system hibernation or when codec has subordinates like LEDs.
So if the codec is prepared for direct-complete but PM core still calls
codec's suspend or freeze callback, partially revert the commit and take
the original approach, which uses pm_runtime_force_*() helpers to
ensure PM refcount are balanced. Meanwhile, still keep prepare() and
complete() callbacks to enable direct-complete and request a resume for
jack detection, respectively.

For performance, BO page mappings can stay in place even if the
map counter has returned to 0. In these cases, the existing page
mapping has to be reused by the next vmap operation. Otherwise
a new mapping would be installed and the old mapping's pages leak.

isolation. We had wired up individual engine resets for gen6, but only
enabled it from gen8; now let's turn it on for the forgotten gen7. gen6

Before the commit 896fbe20b4e2333fb55 ("printk: use the lockless
ringbuffer"), msg_print_text() would only write up to size-1 bytes
into the provided buffer. Some callers expect this behavior and
append a terminator to returned string. In particular:
arch/powerpc/xmon/xmon.c:dump_log_buf()
arch/um/kernel/kmsg_dump.c:kmsg_dumper_stdout()
msg_print_text() has been replaced by record_print_text(), which
currently fills the full size of the buffer. This causes a
buffer overflow for the above callers.
Change record_print_text() so that it will only use size-1 bytes
for text data. Also, for paranoia sakes, add a terminator after
the text data.
And finally, document this behavior so that it is clear that only
size-1 bytes are used and a terminator is added.

We have DRM drivers based on USB, SPI and platform devices. All of them
are fine with storing their device reference in struct drm_device.dev.
PCI devices should be no exception. Therefore struct drm_device.pdev is
deprecated.
Instead upcast from struct drm_device.dev with to_pci_dev(). PCI-specific
code can use dev_is_pci() to test for a PCI device. This patch changes

The TCP session does not terminate with TCP_USER_TIMEOUT when data
remain untransmitted due to zero window.
The number of unanswered zero-window probes (tcp_probes_out) is
reset to zero with incoming acks irrespective of the window size,
as described in tcp_probe_timer():
RFC 1122 4.2.2.17 requires the sender to stay open indefinitely
as long as the receiver continues to respond probes. We support
this by default and reset icsk_probes_out with incoming ACKs.
This counter, however, is the wrong one to be used in calculating the
duration that the window remains closed and data remain untransmitted.
Thanks to Jonathan Maxwell <jmaxwell37@gmail.com> for diagnosing the
actual issue.
In this patch a new timestamp is introduced for the socket in order to
track the elapsed time for the zero-window probes that have not been
answered with any non-zero window ack.

Since main() does not return a value explicitly, the
return values from FAIL_IF() conditions are ignored
and the tests can still pass irrespective of failures.
This makes sure that we always explicitly return the
correct test exit status.

mv88e6xxx_port_vlan_join checks whether the VTU already contains an
entry for the given vid (via mv88e6xxx_vtu_getnext), and if so, merely
changes the relevant .member[] element and loads the updated entry
into the VTU.
However, at least for the mv88e6250, the on-stack struct
mv88e6xxx_vtu_entry vlan never has its .state[] array explicitly
initialized, neither in mv88e6xxx_port_vlan_join() nor inside the
getnext implementation. So the new entry has random garbage for the
STU bits, breaking VLAN filtering.
When the VTU entry is initially created, those bits are all zero, and
we should make sure to keep them that way when the entry is updated.

The recently added thermal policy support makes a
hp_wmi_perform_query(0x4c, ...) call on older devices which do not
support thermal policies this causes the following warning to be
logged (seen on a HP Stream x360 Convertible PC 11):
[ 26.805305] hp_wmi: query 0x4c returned error 0x3
Error 0x3 is HPWMI_RET_UNKNOWN_COMMAND error. This commit silences
the warning for unknown-command errors, silencing the new warning.

The blamed commit was too aggressive, and it made ocelot_netdevice_event
react only to network interface events emitted for the ocelot switch
ports.
In fact, only the PRECHANGEUPPER should have had that check.
When we ignore all events that are not for us, we miss the fact that the
upper of the LAG changes, and the bonding interface gets enslaved to a
bridge. This is an operation we could offload under certain conditions.

THe HP Stream x360 Convertible PC 11 DSDT has the following VGBS function:
Method (VGBS, 0, Serialized)
{
If ((^^PCI0.LPCB.EC0.ROLS == Zero))
{
VBDS = Zero
}
Else
{
VBDS = Zero
}
Return (VBDS) /* \_SB_.VGBI.VBDS */
}
Which is obviously wrong, because it always returns 0 independent of the
2-in-1 being in laptop or tablet mode. This causes the intel-vbtn driver
to initially report SW_TABLET_MODE = 1 to userspace, which is known to
cause problems when the 2-in-1 is actually in laptop mode.
During earlier testing this turned out to not be a problem because the
2-in-1 would do a Notify(..., 0xCC) or Notify(..., 0xCD) soon after
the intel-vbtn driver loaded, correcting the SW_TABLET_MODE state.
Further testing however has shown that this Notify() soon after the
intel-vbtn driver loads, does not always happen. When the Notify
does not happen, then intel-vbtn reports SW_TABLET_MODE = 1 resulting in
a non-working touchpad.
IOW the tablet-mode reporting is not reliable on this device, so it
should be dropped from the allow-list, fixing the touchpad sometimes
not working.

As of the "arm64: expose FAR_EL1 tag bits in siginfo" patch, the address
that is passed to report_tag_fault has pointer tags in the format of 0x0X,
while KASAN uses 0xFX format (note the difference in the top 4 bits).
Fix up the pointer tag for kernel pointers in do_tag_check_fault by
setting them to the same value as bit 55. Explicitly use __untagged_addr()
instead of untagged_addr(), as the latter doesn't affect TTBR1 addresses.

The function nvmet_execute_identify_ns() doesn't set the status if call
to nvmet_find_namespace() fails. In that case we set the status of the
request to the value return by the nvmet_copy_sgl().
Set the status to NVME_SC_INVALID_NS and adjust the code such that
request will have the right status on nvmet_find_namespace() failure.
