USB: sierra: avoid CDC class functions on "68A3" devices

Sierra Wireless Direct IP devices using the 68A3 product ID
can be configured for modes including a CDC ECM class function.
The known example uses interface numbers 12 and 13 for the ECM
control and data interfaces respectively, consistent with CDC
MBIM function interface numbering on other Sierra devices.

It seems cleaner to restrict this driver to the ff/ff/ff
vendor specific interfaces rather than increasing the already
long interface number blacklist.  This should be more future
proof if Sierra adds more class functions using interface
numbers not yet in the blacklist.

CONFIG_NETFILTER_XT_TARGET_LOG is not selected anymore when jumping

NF_LOG_IPV6 switches.

Change this to select the three new symbols NF_LOG_COMMON, NF_LOG_IPV4

arm64: fix bug for reloading FPSIMD state after cpu power off

Now arm64 defers reloading FPSIMD state, but this optimization also
introduces the bug after cpu resume back from low power mode.

The reason is after the cpu has been powered off, s/w need set the
cpu's fpsimd_last_state to NULL so that it will force to reload
FPSIMD state for the thread, otherwise there has the chance to meet
the condition for both the task's fpsimd_state.cpu field contains the
id of the current cpu, and the cpu's fpsimd_last_state per-cpu variable
points to the task's fpsimd_state, so finally kernel will skip to reload
the context during it return back to userland.

ata: Disabling the async PM for JMicron chip 363/361

After enabled the PM feature that supporting async noirq(76569faa62
(PM / sleep: Asynchronous threads for resume_noirq)),
Jay hit the system resuming issue, that one of the JMicron controller
can not be powered up.

His device tree is like below:
             +-1c.4-[02]--+-00.0  JMicron Technology Corp. JMB363 SATA/IDE Controller
             |            \-00.1  JMicron Technology Corp. JMB363 SATA/IDE Controller

After investigation, we found the the Micron chip 363 included
one SATA controller(0000:02:00.0) and one PATA controller(0000:02:00.1),
these two controllers do not have parent-children relationship,
but the PATA controller only can be powered on after the SATA controller
has finished the powering on.

If we enabled the async noirq(), then the below error is hit during noirq
phase:
pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3

Here for JMicron chip 363/361, we need forcedly to disable the async method.

In the HPD pulse handler we check for long pulses if the port is actually

GM45 systems as well, so we need to use a diffent check.

This patch refactors the digital port connected check out of the g4x detection
path and reuses it in the hpd pulse path.

Fix this by moving the request_irq out of the critical section. This
should be okay since smmu_domain->smmu is still being protected by the
critical section. Also, we still don't program the Stream Match Register
until after registering our interrupt handler so we shouldn't be missing
any interrupts.

ACPI / video: Fix use_native_backlight selection logic

Commit 751109aad583 ("ACPI / video: Change the default for
video.use_native_backlight to 1") has changed the default for
use_native_backlight from 0 to 1, but instead of changing
use_native_backlight_dmi to true, and leaving use_native_backlight_param at -1,
it has changed use_native_backlight_param to 1.

This causes acpi_video_use_native_backlight() to always think that a value was
specified through the param, making it impossible to add a dmi based quirk
to force 0 now that the default is 1.

This fixes this by restoring the use_native_backlight_param default to -1, and
instead setting the use_native_backlight_dmi default to true.
