We want to display the transport address of the connected host
in debugfs, but this is a property of the transport.
So add a callback 'host_traddr' to allow the transport drivers
to fill in the data.

Combining both creates an ambiguous cleanup scenario for the caller if
an error is returned: does the device reference need to be dropped or
did the error occur before the device was initialized? If an error
occurs after the device is added, then the existing cleanup routines
will leak memory.
Furthermore, the nvme core is taking it upon itself to free the device's
kobj name under certain conditions rather than go through the core
device API. We shouldn't be peaking into these implementation details.
Split the device initialization from the addition to make it easier to
know the error handling actions, fix the existing memory leaks, and stop
the device layering violations.

It is reported that single-thread performance on some hybrid systems
dropped significantly after commit 7feec7430edd ("ACPI: CPPC: Only probe
for _CPC if CPPC v2 is acked") which prevented _CPC from being used if
the support for it had not been confirmed by the platform firmware.
The problem is that if the platform firmware does not confirm CPPC v2
support, cppc_get_perf_caps() returns an error which prevents the
intel_pstate driver from enabling ITMT. Consequently, the scheduler
does not get any hints on CPU performance differences, so in a hybrid
system some tasks may run on CPUs with lower capacity even though they
should be running on high-capacity CPUs.
To address this, modify intel_pstate to use the information from
MSR_HWP_CAPABILITIES to enable ITMT if CPPC is not available (which is
done already if the highest performance number coming from CPPC is not
realistic).

The distributor and PMR/RPR can present different views of the interrupt
priority space dependent upon the values of GICD_CTLR.DS and
SCR_EL3.FIQ. Currently we treat the distributor's view of the priority
space as canonical, and when the two differ we change the way we handle
values in the PMR/RPR, using the `gic_nonsecure_priorities` static key
to decide what to do.
This approach works, but it's sub-optimal. When using pseudo-NMI we
manipulate the distributor rarely, and we manipulate the PMR/RPR
registers very frequently in code spread out throughout the kernel (e.g.
local_irq_{save,restore}()). It would be nicer if we could use fixed
values for the PMR/RPR, and dynamically choose the values programmed
into the distributor.
This patch changes the GICv3 driver and arm64 code accordingly. PMR
values are chosen at compile time, and the GICv3 driver determines the
appropriate values to program into the distributor at boot time. This
removes the need for the `gic_nonsecure_priorities` static key and
results in smaller and better generated code for saving/restoring the
irqflags.
Before this patch, local_irq_disable() compiles to:
| 0000000000000000 <outlined_local_irq_disable>:
| 0: d503201f nop
| 4: d50343df msr daifset, #0x3

| 1c: d2801400 mov x0, #0xa0 // #160
| 20: 17fffffd b 14 <outlined_local_irq_disable+0x14>
After this patch, local_irq_disable() compiles to:
| 0000000000000000 <outlined_local_irq_disable>:
| 0: d503201f nop
| 4: d50343df msr daifset, #0x3

| 10: d5184600 msr icc_pmr_el1, x0
| 14: d65f03c0 ret
... with 3 fewer instructions per call.
For defconfig + CONFIG_PSEUDO_NMI=y, this results in a minor saving of
~4K of text, and will make it easier to make further improvements to the
way we manipulate irqflags and DAIF bits.

In subsequent patches the GICv3 driver will choose the regular interrupt
priority at boot time, dependent on the configuration of GICD_CTRL.DS
and SCR_EL3.FIQ. This will need to be chosen before we configure the
distributor with default prioirities for all the interrupts, which
happens before we currently detect these in gic_cpu_sys_reg_init().
Add a new gic_prio_init() function to detect these earlier and log them
to the console so that any problems can be debugged more easily. This
also allows the uniformity checks in gic_cpu_sys_reg_init() to be
simplified, as we can compare directly with the boot CPU values which
were recorded earlier.

In subsequent patches the GICv3 driver will choose the regular interrupt
priority at boot time.
In preparation for using dynamic priorities, place the priorities in
variables and update the code to pass these as parameters. Users of
GICD_INT_DEF_PRI_X4 are modified to replicate the priority byte using
REPEAT_BYTE_U32().
There should be no functional change as a result of this patch.

The gic_configure_irq(), gic_dist_config(), and gic_cpu_config()
functions each take an optional "sync_access" callback, but in almost
all cases this is not used. The only user is the GICv3 driver's
gic_cpu_init() function, which uses gic_redist_wait_for_rwp() as the
"sync_access" callback for gic_cpu_config().
It would be simpler and clearer to remove the callback and have the
GICv3 driver call gic_redist_wait_for_rwp() explicitly after
gic_cpu_config().
Remove the "sync_access" callback, and call gic_redist_wait_for_rwp()
explicitly in the GICv3 driver.
There should be no functional change as a result of this patch.

With WoWLAN enabled and after sleeping for a rather long time,
we are seeing that with some APs, it is not able to wake up
the STA though the correct wake up pattern has been configured.
This is because the host doesn't send keepalive command to
firmware, thus firmware will not send any packet to the AP and
after a specific time the AP kicks out the STA.
So enable keepalive before going to suspend and disable it after
resume back.

In case of legacy cursor update, the cursor VMA needs to be unpinned
only after vblank. This exceeds the lifetime of the whole atomic commit.
Any trick I attempted to keep the atomic commit alive didn't work, as
drm_atomic_helper_setup_commit() force throttles on any old commit that
wasn't cleaned up.
The only option remaining is to remove the plane from the atomic commit,
and use the same path as the legacy cursor update to clean the state
after vblank.
Changes since previous version:
- Call the memset for plane state immediately when scheduling vblank,
this prevents a use-after-free in cursor cleanup.

The cursor hardware only does sync updates, and thus the hardware
will be scanning out from the old fb until the next start of vblank.
So in order to make the legacy cursor fastpath actually safe we
should not unpin the old fb until we're sure the hardware has
ceased accessing it. The simplest approach is to just use a vblank
work here to do the delayed unpin.
Not 100% sure it's a good idea to put this onto the same high
priority vblank worker as eg. our timing critical gamma updates.
But let's keep it simple for now, and it we later discover that
this is causing problems we can think about adding a lower
priority worker for such things.
This patch is slightly reworked by Maarten

In some cases we want to flush all vblank work, right before vblank_off
for example. Add a simple function to make this possible.
Check that both pending_work and running work are empty when flushing.

The Kconfig for platforms/arm64 has 'depends on ARM64 || COMPILE_TEST'.
However due to Makefile having just obj-$(CONFIG_ARM64) the subdir will
not be descended for !ARM64 platforms and thus the drivers won't get
built. This breaks modular builds of other driver drivers which depend
on arm64 platform drivers.
