Remove the bogus #ifdef and __maybe_unused annation on the global

As the function definition is still in the #ifdef block, this leads

Rasmus Villemoes 6cf103bc03 pinctrl: freescale: remove generic pin config core support
No instance of "struct imx_pinctrl_soc_info" sets '.generic_pinconf =
true', so all of this is effectively dead code.

To make it easier to understand the actual code, remove all the unused
cruft. This effectively reverts a5cadbbb08 ("pinctrl: imx: add
generic pin config core support").

It was only in use by a single SOC (imx7ulp) for a few releases, and
the commit message of dbffda08f0 ("pinctrl: fsl: imx7ulp: change to
use imx legacy binding") suggests that it won't be used in the
future. Certainly no new user has appeared in 20+ releases, and should
the need arise, this can be dug out of git history again.

Linus Torvalds 596ff4a09b cpumask: re-introduce constant-sized cpumask optimizations
Commit aa47a7c215 ("lib/cpumask: deprecate nr_cpumask_bits") resulted
in the cpumask operations potentially becoming hugely less efficient,
because suddenly the cpumask was always considered to be variable-sized.

The optimization was then later added back in a limited form by commit
6f9c07be9d ("lib/cpumask: add FORCE_NR_CPUS config option"), but that
FORCE_NR_CPUS option is not useful in a generic kernel and more of a
special case for embedded situations with fixed hardware.

Instead, just re-introduce the optimization, with some changes.

Instead of depending on CPUMASK_OFFSTACK being false, and then always
using the full constant cpumask width, this introduces three different
cpumask "sizes":

 - the exact size (nr_cpumask_bits) remains identical to nr_cpu_ids.

   This is used for situations where we should use the exact size.

 - the "small" size (small_cpumask_bits) is the NR_CPUS constant if it
   fits in a single word and the bitmap operations thus end up able
   to trigger the "small_const_nbits()" optimizations.

   This is used for the operations that have optimized single-word
   cases that get inlined, notably the bit find and scanning functions.

 - the "large" size (large_cpumask_bits) is the NR_CPUS constant if it
   is an sufficiently small constant that makes simple "copy" and
   "clear" operations more efficient.

   This is arbitrarily set at four words or less.

As a an example of this situation, without this fixed size optimization,
cpumask_clear() will generate code like

        movl    nr_cpu_ids(%rip), %edx
        addq    $63, %rdx
        shrq    $3, %rdx
        andl    $-8, %edx
        callq   memset@PLT

on x86-64, because it would calculate the "exact" number of longwords
that need to be cleared.

In contrast, with this patch, using a MAX_CPU of 64 (which is quite a
reasonable value to use), the above becomes a single

	movq $0,cpumask

instruction instead, because instead of caring to figure out exactly how
many CPU's the system has, it just knows that the cpumask will be a
single word and can just clear it all.

Note that this does end up tightening the rules a bit from the original
version in another way: operations that set bits in the cpumask are now
limited to the actual nr_cpu_ids limit, whereas we used to do the
nr_cpumask_bits thing almost everywhere in the cpumask code.

But if you just clear bits, or scan for bits, we can use the simpler
compile-time constants.

In the process, remove 'cpumask_complement()' and 'for_each_cpu_not()'
which were not useful, and which fundamentally have to be limited to
'nr_cpu_ids'.  Better remove them now than have somebody introduce use
of them later.

Of course, on x86-64 with MAXSMP there is no sane small compile-time
constant for the cpumask sizes, and we end up using the actual CPU bits,
and will generate the above kind of horrors regardless.  Please don't
use MAXSMP unless you really expect to have machines with thousands of
cores.

Linus Torvalds 1a8d05a726 VM_FAULT_RETRY fixes
Some of the page fault handlers do not deal with the following case
 correctly:
 	* handle_mm_fault() has returned VM_FAULT_RETRY
 	* there is a pending fatal signal
 	* fault had happened in kernel mode
 Correct action in such case is not "return unconditionally" - fatal
 signals are handled only upon return to userland and something like
 copy_to_user() would end up retrying the faulting instruction and
 triggering the same fault again and again.
 
 What we need to do in such case is to make the caller to treat that
 as failed uaccess attempt - handle exception if there is an exception
 handler for faulting instruction or oops if there isn't one.
 
 Over the years some architectures had been fixed and now are handling
 that case properly; some still do not.  This series should fix the
 remaining ones.
 
 Status:
 	m68k, riscv, hexagon, parisc: tested/acked by maintainers.
 	alpha, sparc32, sparc64: tested locally - bug has been
 reproduced on the unpatched kernel and verified to be fixed by
 this series.
 	ia64, microblaze, nios2, openrisc: build, but otherwise
 completely untested.
