Add documentation for the pin controller found on the Renesas RZ/V2N
(R9A09G056) SoC. The RZ/V2N PFC differs slightly from the RZ/G2L family
and is almost identical to the RZ/V2H(P) SoC, except that the RZ/V2H(P) SoC
has an additional dedicated pin.

To account for this, a SoC-specific compatible string,
'renesas,r9a09g056-pinctrl', is introduced for the RZ/V2N SoC.

6f110a5e4f Disable SLUB_TINY for build testing
... 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.

eb187540d1 tools/power turbostat: Increase CPU_SUBSET_MAXCPUS to 8192
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.

ff0c66685d A set of updates for the interrupt subsystem:
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.

Pull more irq updates from Thomas Gleixner:
 "A set of updates for the interrupt subsystem:

   - 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.

   - 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"

a91c49517d A revert to fix a adjtimex() regression:
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").
