Current Kconfig menu at [ALSA for SoC audio support] has no rules.
So, some venders are using menu style, some venders are listed each drivers
on top page, etc. It is difficult to find target vender and/or drivers
because it is very random.

The mailbox controller driver for the Microchip Inter-processor
Communication can be built as a module. It uses cpuid_to_hartid_map and
commit 4783ce32b080 ("riscv: export __cpuid_to_hartid_map") enables that
to work for SMP. However, cpuid_to_hartid_map uses boot_cpu_hartid on
non-SMP kernels and this driver can be useful in such configurations[1].
Export boot_cpu_hartid so the driver can be built as a module on non-SMP
kernels as well.

This reverts commit ad5643cf2f69 ("riscv: Define TASK_SIZE_MAX for
__access_ok()").
This commit changes TASK_SIZE_MAX to be LONG_MAX to optimize access_ok(),
because the previous TASK_SIZE_MAX (default to TASK_SIZE) requires some
computation.
The reasoning was that all user addresses are less than LONG_MAX, and all
kernel addresses are greater than LONG_MAX. Therefore access_ok() can
filter kernel addresses.
Addresses between TASK_SIZE and LONG_MAX are not valid user addresses, but
access_ok() let them pass. That was thought to be okay, because they are
not valid addresses at hardware level.
Unfortunately, one case is missed: get_user_pages_fast() happily accepts
addresses between TASK_SIZE and LONG_MAX. futex(), for instance, uses
get_user_pages_fast(). This causes the problem reported by Robert [1].
Therefore, revert this commit. TASK_SIZE_MAX is changed to the default:
TASK_SIZE.
This unfortunately reduces performance, because TASK_SIZE is more expensive
to compute compared to LONG_MAX. But correctness first, we can think about
optimization later, if required.

access handling"
This reverts commit 61a74ad25462 ("riscv: misaligned: fix sleeping function
called during misaligned access handling"). The commit addresses a sleeping
in atomic context problem, but it is not the correct fix as explained by
Clément:
"Using nofault would lead to failure to read from user memory that is paged
out for instance. This is not really acceptable, we should handle user
misaligned access even at an address that would generate a page fault."
This bug has been properly fixed by commit 453805f0a28f ("riscv:
misaligned: enable IRQs while handling misaligned accesses").
Revert this improper fix.

cmos_interrupt() can be called in a non-interrupt context, such as in
an ACPI event handler (which runs in an interrupt thread). Therefore,
usage of spin_lock(&rtc_lock) is insecure. Use spin_lock_irqsave() /
spin_unlock_irqrestore() instead.
Before a misguided
commit 6950d046eb6e ("rtc: cmos: Replace spin_lock_irqsave with spin_lock in hard IRQ")
the cmos_interrupt() function used spin_lock_irqsave(). That commit
changed it to spin_lock() and broke locking, which was partially fixed in
commit 13be2efc390a ("rtc: cmos: Disable irq around direct invocation of cmos_interrupt()")
That second commit did not take account of the ACPI fixed event handler
pathway, however. It introduced local_irq_disable() workarounds in
cmos_check_wkalrm(), which can cause problems on PREEMPT_RT kernels
and are now unnecessary.
Add an explicit comment so that this change will not be reverted by
mistake.

The bridge used in drm_connector_hdmi_audio_init() does not correctly
point to the required audio bridge, which lead to incorrect audio
configuration input.

Instead of the open-coded read/modify/write sequence, we can simply use
the regmap helpers regmap_set_bits() and regmap_update_bits()
respectively.
This makes the code easier to read, and avoids extra work in case the
underlying bus supports updating bits via
struct regmap_bus::reg_update_bits() directly (which is the case for
S2MPG10 on gs101 where this driver communicates via ACPM).

The regmap_clear_bits() and regmap_set_bits() helper macros state the
intention a bit more obviously.
Use those.

To release memory allocated by device_init_wakeup(true), drivers have
to call device_init_wakeup(false) in error paths and unbind.
Switch to the new devres managed version devm_device_init_wakeup() to
plug this memleak.

Add support for Samsung's S2MPG10 PMIC RTC, which is similar to the
existing PMIC RTCs supported by this driver.
S2MPG10 doesn't use I2C, so we expect the core driver to have created a
regmap for us.
Additionally, it can be used for doing a cold-reset. If requested to do
so (via DT), S2MPG10 is programmed with a watchdog configuration that
will perform a full power cycle upon watchdog expiry.
