Currently we have a single function slab_free() handling both single
object freeing and bulk freeing with necessary hooks, the latter case
requiring slab_free_freelist_hook(). It should be however better to
distinguish the two use cases for the following reasons:

- code simpler to follow for the single object case

- better code generation - although inlining should eliminate the
  slab_free_freelist_hook() for single object freeing in case no
  debugging options are enabled, it seems it's not perfect. When e.g.
  KASAN is enabled, we're imposing additional unnecessary overhead for
  single object freeing.

- preparation to add percpu array caches in near future

Therefore, simplify slab_free() for the single object case by dropping
unnecessary parameters and calling only slab_free_hook() instead of
slab_free_freelist_hook(). Rename the bulk variant to slab_free_bulk()
and adjust callers accordingly.

While at it, flip (and document) slab_free_hook() return value so that
it returns true when the freeing can proceed, which matches the logic of
slab_free_freelist_hook() and is not confusingly the opposite.

Additionally we can simplify a bit by changing the tail parameter of
do_slab_free() when freeing a single object - instead of NULL we can set
it equal to head.

bloat-o-meter shows small code reduction with a .config that has KASAN
etc disabled:

Currently, when __kmem_cache_alloc_bulk() fails, it frees back the
objects that were allocated before the failure, using
kmem_cache_free_bulk(). Because kmem_cache_free_bulk() calls the free
hooks (KASAN etc.) and those expect objects that were processed by the
post alloc hooks, slab_post_alloc_hook() is called before
kmem_cache_free_bulk().

This is wasteful, although not a big concern in practice for the rare
error path. But in order to efficiently handle percpu array batch refill
and free in the near future, we will also need a variant of
kmem_cache_free_bulk() that avoids the free hooks. So introduce it now
and use it for the failure path.

In case of failure we however still need to perform memcg uncharge so
handle that in a new memcg_slab_alloc_error_hook(). Thanks to Chengming
Zhou for noticing the missing uncharge.

As a consequence, __kmem_cache_alloc_bulk() no longer needs the objcg
parameter, remove it.

With allocation fastpaths no longer divided between two .c files, we
have better inlining, however checking the disassembly of
kmem_cache_alloc() reveals we can do better to make the fastpaths
smaller and move the less common situations out of line or to separate
functions, to reduce instruction cache pressure.

- split memcg pre/post alloc hooks to inlined checks that use likely()
  to assume there will be no objcg handling necessary, and non-inline
  functions doing the actual handling

- add some more likely/unlikely() to pre/post alloc hooks to indicate
  which scenarios should be out of line

- change gfp_allowed_mask handling in slab_post_alloc_hook() so the
  code can be optimized away when kasan/kmsan/kmemleak is configured out

To avoid unnecessary bloat, remove all size checks/warnings from
kmalloc_slab() as they just duplicate those in callers, especially after
recent changes to kmalloc_size_roundup(). We just need to adjust handling
of zero size in __do_kmalloc_node(). Also we can stop handling NULL
result from kmalloc_slab() there as that now cannot happen (unless
called too early during boot).

 - Documentation update: Add a note about argument and return value
   fetching is the best effort because it depends on the type.

 - objpool: Fix to make internal global variables static in
   test_objpool.c.

 - kprobes: Unify kprobes_exceptions_nofify() prototypes. There are the
   same prototypes in asm/kprobes.h for some architectures, but some of
   them are missing the prototype and it causes a warning. So move the
   prototype into linux/kprobes.h.

 - tracing: Fix to check the tracepoint event and return event at
   parsing stage. The tracepoint event doesn't support %return but if
   $retval exists, it will be converted to %return silently. This finds
   that case and rejects it.

 - tracing: Fix the order of the descriptions about the parameters of
   __kprobe_event_gen_cmd_start() to be consistent with the argument
   list of the function.

The order of descriptions should be consistent with the argument list of
the function, so "kretprobe" should be the second one.

                                 const char *name, const char *loc, ...)

  MediaTek firmware:

   - Move the MediaTek GIC quirk handling from irqchip to core. Before
     the merging window commit 44bd78dd ("irqchip/gic-v3: Disable
     pseudo NMIs on MediaTek devices w/ firmware issues") temporarily
     addressed this issue. Fixed now at a deeper level in the arch code

   - Reject events meant for other PMUs in the CoreSight PMU driver,
     otherwise some of the core PMU events would disappear

   - Fix the Armv8 PMUv3 driver driver to not truncate 64-bit registers,
     causing some events to be invisible

   - Remove duplicate declaration of __arm64_sys##name following the
     patch to avoid prototype warning for syscalls
