irqchip/gic-v3-its: Limit memreserve cpuhp state lifetime

The new memreserve cpuhp callback only needs to survive up until a point
where every CPU in the system has booted once. Beyond that, it becomes a
no-op and can be put in the bin.

irqchip/gic-v3-its: Postpone LPI pending table freeing and memreserve

Memory used by the LPI tables have to be made persistent for kexec to have
a chance to work, as explained in [1]. If they have been made persistent
and we are booting into a kexec'd kernel, we also need to free the pages
that were preemptively allocated by the new kernel for those tables.

Both of those operations currently happen during its_cpu_init(), which
happens in a _STARTING (IOW atomic) cpuhp callback for secondary
CPUs. efi_mem_reserve_iomem() issues a GFP_ATOMIC allocation, which
unfortunately doesn't work under PREEMPT_RT (this ends up grabbing a
non-raw spinlock, which can sleep under PREEMPT_RT). Similarly, freeing the
pages ends up grabbing a sleepable spinlock.

Since the memreserve is only required by kexec, it doesn't have to be done
so early in the secondary boot process. Issue the reservation in a new
CPUHP_AP_ONLINE_DYN cpuhp callback, and piggy-back the page freeing on top
of it. A CPU gets to run the body of this new callback exactly once.

As kexec issues a machine_shutdown() prior to machine_kexec(), it will be
serialized vs a CPU being plugged to life by the hotplug machinery - either
the CPU will have been brought up and have had its redistributor's pending
table memreserved, or it never went online and will have its table
allocated by the new kernel.

INVALL CMD specifies that the ITS must ensure any caching associated with
the interrupt collection defined by ICID is consistent with the LPI
configuration tables held in memory for all Redistributors. SYNC is
required to ensure that INVALL is executed.

Currently, LPI configuration data may be inconsistent with that in the
memory within a short period of time after the INVALL command is executed.

ASoC: Updates for v5.16

This is an unusually large set of updates, mostly a large crop of
unusually big drivers coupled with extensive overhauls of existing code.
There's a SH change here for the DAI format terminology, the change is
straightforward and the SH maintainers don't seem very active.

- A new version of the audio graph card which supports a wider range of
systems.
- Move of the Cirrus DSP framework into drivers/firmware to allow for
future use by non-audio DSPs.
- Several conversions to YAML DT bindings.
- Continuing cleanups to the SOF and Intel code.
- A very big overhaul of the cs42l42 driver, correcting many problems.
- Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim
MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia
Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS,

Merge irqchip updates for Linux 5.16 from Marc Zyngier:

- A large cross-arch rework to move irq_enter()/irq_exit() into
the arch code, and removing it from the generic irq code.
Thanks to Mark Rutland for the huge effort!

- A few irqchip drivers are made modular (broadcom, meson), because
that's apparently a thing...

- A new driver for the Microchip External Interrupt Controller

- The irq_cpu_offline()/irq_cpu_online() API is now deprecated and
can only be selected on the Cavium Octeon platform. Once this
platform is removed, the API will be removed at the same time.

- A sprinkle of devm_* helper, as people seem to love that.

- The usual spattering of small fixes and minor improvements.
