d7f5e83913 arm64: dts: rockchip: Drop RTC clock-frequency on rk3588-rock-5b
The hym8563 RTC driver doesn't handle the 'clock-frequency' property,
which is also indicated by the following dtbs_check warning:

  rk3588-rock-5b.dtb: rtc@51: Unevaluated properties are not allowed ('clock-frequency' was unexpected)
  From schema: Documentation/devicetree/bindings/rtc/haoyu,hym8563.yaml

Drop the unsupported property.

87810bda8a arm64: dts: rockchip: Fix SCMI assigned clocks on rk3588s
Since commit df4fdd0db475 ("dt-bindings: firmware: arm,scmi: Restrict
protocol child node properties") the following dtbs_check warning is
shown:

  rk3588-rock-5b.dtb: scmi: protocol@14: Unevaluated properties are not
  allowed ('assigned-clock-rates', 'assigned-clocks' were unexpected)

Because adding the missing properties to firmware/arm,scmi.yaml binding
document was not an acceptable solution, move SCMI_CLK_CPUB01 and
SCMI_CLK_CPUB23 assigned clocks to the related CPU nodes and also add
the missing SCMI_CLK_CPUL.

Additionally, adjust frequency to 816 MHz for all the above mentioned
assigned clocks, in order to match the firmware defaults.

596ff4a09b cpumask: re-introduce constant-sized cpumask optimizations
Commit aa47a7c215e7 ("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
6f9c07be9d02 ("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.

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.

95207db816 Remove Intel compiler support
include/linux/compiler-intel.h had no update in the past 3 years.

We often forget about the third C compiler to build the kernel.

For example, commit a0a12c3ed057 ("asm goto: eradicate CC_HAS_ASM_GOTO")
only mentioned GCC and Clang.

init/Kconfig defines CC_IS_GCC and CC_IS_CLANG but not CC_IS_ICC,
and nobody has reported any issue.

I guess the Intel Compiler support is broken, and nobody is caring
about it.

Harald Arnesen pointed out ICC (classic Intel C/C++ compiler) is
deprecated:

    $ icc -v
    icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is
    deprecated and will be removed from product release in the second half
    of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended
    compiler moving forward. Please transition to use this compiler. Use
    '-diag-disable=10441' to disable this message.
    icc version 2021.7.0 (gcc version 12.1.0 compatibility)

Arnd Bergmann provided a link to the article, "Intel C/C++ compilers

e77d587a2c mm: avoid gcc complaint about pointer casting
The migration code ends up temporarily stashing information of the wrong
type in unused fields of the newly allocated destination folio.  That
all works fine, but gcc does complain about the pointer type mis-use:

    mm/migrate.c: In function ‘__migrate_folio_extract’:
    mm/migrate.c:1050:20: note: randstruct: casting between randomized structure pointer types (ssa): ‘struct anon_vma’ and ‘struct address_space’

     1050 |         *anon_vmap = (void *)dst->mapping;
          |         ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~

and gcc is actually right to complain since it really doesn't understand
that this is a very temporary special case where this is ok.

This could be fixed in different ways by just obfuscating the assignment
sufficiently that gcc doesn't see what is going on, but the truly
"proper C" way to do this is by explicitly using a union.

Using unions for type conversions like this is normally hugely ugly and
syntactically nasty, but this really is one of the few cases where we
want to make it clear that we're not doing type conversion, we're really
re-using the value bit-for-bit just using another type.

IOW, this should not become a common pattern, but in this one case using
that odd union is probably the best way to document to the compiler what
is conceptually going on here.

[ Side note: there are valid cases where we convert pointers to other
  pointer types, notably the whole "folio vs page" situation, where the
  types actually have fundamental commonalities.

  The fact that the gcc note is limited to just randomized structures
  means that we don't see equivalent warnings for those cases, but it
  migth also mean that we miss other cases where we do play these kinds
  of dodgy games, and this kind of explicit conversion might be a good
  idea. ]

I verified that at least for an allmodconfig build on x86-64, this
generates the exact same code, apart from line numbers and assembler
comment changes.
