Utilize card->deferrable flag to support delayed card enumeration -
scenario where snd_soc_register_card() occurs before all the required
card components are registered into the framework.

Since commit e894efef9a ("ASoC: core: add support to card rebind")
there is a support for card rebind. The support is only partial though.
Let's consider the following scenarios both of which aim to enumerate a
sound card:
1)
snd_soc_add_component(comp1);
(...)
snd_soc_register_card(card1);
2)
snd_soc_register_card(card1);
(...)
snd_soc_add_component(comp1);
For the sake of simplicity, let comp1 be the last dependency needed for
the card1 to enumerate.
Case 1) will end up succeeding whereas 2) is a certain fail -
snd_soc_bind_card() does not honor unbind_card_list so even a non-fatal
return code of EPROBE_DEFER will cause the card to collapse. Given the
typical usecase of platform_device serving as a card->dev and its
probe() ending with:
int carddev_probe(struct platform_device *pdev)
{
(...)
return devm_snd_soc_register_card(dev, card);
}
failure to register card triggers device_unbind_cleanup() -
really_probe() in dd.c.
To allow for card registration to be deferred while being friendly
towards existing users of devm_snd_soc_register_card(), add new
card->devres_dev field, and devm_xxx() variants for card registration:
devm_snd_soc_register_deferrable_card() (external)
devm_snd_soc_bind_card() (internal)
In essence, if requested, devm_snd_soc_bind_card() replaces
snd_soc_bind_card(). The rebind procedure takes care of destroying
old devres before attempting the new bind. This makes sure nothing is
left hanging if binding fails and card becomes unbound but is still
registered to the ASoC framework.
To allow snd_soc_bind_card() to be reused by the deferrable friends,
move 'client_mutex' locking to the function's callers and select between
devm_xxx and non-devm_xxx variants of snd_soc_bind_card() based on
card->devres_dev.
On top of the feature, the refactoring brings two benefits:
a) single lock/unlock of 'client_mutex' in snd_soc_add_component()
instead of ambiguous unlock and immediate lock in
snd_soc_try_rebind_card()
b) all unbind_card_list manipulations done under 'client_mutex'

Move the get_ctx(child_ctx) call and the child_event->ctx assignment to
occur immediately after the child event is allocated. Ensure that
child_event->ctx is non-NULL before any subsequent error path within
inherit_event calls free_event(), satisfying the assumptions of the
cleanup code.
Details:
There's no clear Fixes tag, because this bug is a side-effect of
multiple interacting commits over time (up to 15 years old), not
a single regression.
The code initially incremented refcount then assigned context
immediately after the child_event was created. Later, an early
validity check for child_event was added before the
refcount/assignment. Even later, a WARN_ON_ONCE() cleanup check was
added, assuming event->ctx is valid if the pmu_ctx is valid.
The problem is that the WARN_ON_ONCE() could trigger after the initial
check passed but before child_event->ctx was assigned, violating its
precondition. The solution is to assign child_event->ctx right after
its initial validation. This ensures the context exists for any
subsequent checks or cleanup routines, resolving the WARN_ON_ONCE().
To resolve it, defer the refcount update and child_event->ctx assignment
directly after child_event->pmu_ctx is set but before checking if the
parent event is orphaned. The cleanup routine depends on
event->pmu_ctx being non-NULL before it verifies event->ctx is
non-NULL. This also maintains the author's original intent of passing
in child_ctx to find_get_pmu_context before its refcount/assignment.

Per DDI0487L.a B2.2.6, atomic instructions are only architecturally
guaranteed for Inner/Outer Shareable Normal Write-Back memory. For
anything else the behavior is IMPLEMENTATION DEFINED and can lose
atomicity, or, in this case, generate an abort.
It would appear that selftests sets up the stage-1 mappings as Non

Shareability field to Inner Shareable for non-LPA2 page tables. Note
that for the LPA2 page table format, translations for cacheable memory

The kvm selftest library for arm64 currently configures the hardware
fields, such as shift and mask in the page-table entries and registers,
directly with numbers. While it add comments at places, it's better to
rewrite them with appropriate macros to improve the readability and
reduce the risk of errors. Hence, introduce macros to define the
hardware fields and use them in the arm64 processor library.
Most of the definitions are primary copied from the Linux's header,

... and don't error out so hard on missing module descriptions.
Before commit 6c6c1fc09d ("modpost: require a MODULE_DESCRIPTION()")
we used to warn about missing module descriptions, but only when
building with extra warnigns (ie 'W=1').
After that commit the warning became an unconditional hard error.
And it turns out not all modules have been converted despite the claims
to the contrary. As reported by Damian Tometzki, the slub KUnit test
didn't have a module description, and apparently nobody ever really
noticed.
The reason nobody noticed seems to be that the slub KUnit tests get
disabled by SLUB_TINY, which also ends up disabling a lot of other code,
both in tests and in slub itself. And so anybody doing full build tests
didn't actually see this failre.
So let's disable SLUB_TINY for build-only tests, since it clearly ends
up limiting build coverage. Also turn the missing module descriptions
error back into a warning, but let's keep it around for non-'W=1'
builds.

On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output:
"turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151"
A similar error appears with the use of turbostat --cpu when the inputted cpu
range contains a cpu number >= 1024:
# turbostat -c 1100-1151
"--cpu 1100-1151" malformed
...
Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS.
It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low.
For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS
brings support for parsing cpu numbers >= 1024.
Increase CPU_SUBSET_MAXCPUS to 8192, a common setting for CONFIG_NR_CPUS on x86_64.

1) Convert all del_timer[_sync]() instances over to the new
timer_delete[_sync]() API and remove the legacy wrappers.
Conversion was done with coccinelle plus some manual fixups as
coccinelle chokes on scoped_guard().
2) The final cleanup of the hrtimer_init() to hrtimer_setup() conversion.
This has been delayed to the end of the merge window, so that all
patches which have been merged through other trees are in mainline and
all new users are catched.
Doing this right before rc1 ensures that new code which is merged post rc1
is not introducing new instances of the original functionality.

1) A treewide cleanup for the irq_domain code, which makes the naming
consistent and gets rid of the original oddity of naming domains
'host'.
This is a trivial mechanical change and is done late to ensure that
all instances have been catched and new code merged post rc1 wont
reintroduce new instances.
2) A trivial consistency fix in the migration code
The recent introduction of irq_force_complete_move() in the core
code, causes a problem for the nostalgia crowd who maintains ia64 out
of tree.
The code assumes that hierarchical interrupt domains are enabled and
dereferences irq_data::parent_data unconditionally. That works in mainline
because both architectures which enable that code have hierarchical domains
enabled. Though it breaks the ia64 build, which enables the functionality,
but does not have hierarchical domains.
While it's not really a problem for mainline today, this
unconditional dereference is inconsistent and trivially fixable by
using the existing helper function irqd_get_parent_data(), which has
the appropriate #ifdeffery in place.

The recent change to prevent that time goes backwards for the coarse time
getters due to immediate multiplier adjustments via adjtimex(), changed the
way how the timekeeping core treats that.
That change result in a regression on the adjtimex() side, which is user
space visible:
1) The forwarding of the base time moves the update out of the original
period and establishes a new one. That's changing the behaviour of the
[PF]LL control, which user space expects to be applied periodically.
2) The clearing of the accumulated NTP error due to #1, changes the
behaviour as well.
It was tried to delay the multiplier/frequency update to the next tick, but
that did not solve the problem as userspace expects that the multiplier or
frequency updates are in effect, when the syscall returns.
There is a different solution for the coarse time problem available, so
revert the offending commit to restore the existing adjtimex() behaviour.
