Add documentation for the pin controller found on the Renesas RZ/V2N

... 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.

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 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"
* tag 'irq-urgent-2025-04-06' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
genirq/migration: Use irqd_get_parent_data() in irq_force_complete_move()
irqdomain: Stop using 'host' for domain
irqdomain: Rename irq_get_default_host() to irq_get_default_domain()
irqdomain: Rename irq_set_default_host() to irq_set_default_domain()
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.

"One important fix and one small configuration update.
The first patch by Artur Rojek fixes an issue with the J2 firmware
loader not being able to find the location of the device tree blob due
to insufficient alignment of the .bss section which rendered J2 boards
unbootable.
The second patch by Johan Korsnes updates the defconfigs on sh to drop
the CONFIG_NET_CLS_TCINDEX configuration option which became obsolete
after 8c710f7525 ("net/sched: Retire tcindex classifier").
