      cpumask: re-introduce constant-sized cpumask optimizations · 596ff4a0
      Linus Torvalds authored
      Commit aa47a7c2 ("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
      6f9c07be ("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.

      Pull VM_FAULT_RETRY fixes from Al Viro:
       "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.

      Remove Intel compiler support · 95207db8
      Masahiro Yamada authored
      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 a0a12c3e ("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

      mm: avoid gcc complaint about pointer casting · e77d587a
      Linus Torvalds authored
      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.

      umh: simplify the capability pointer logic · e7783615
      Linus Torvalds authored
      The usermodehelper code uses two fake pointers for the two capability
      cases: CAP_BSET for reading and writing 'usermodehelper_bset', and
      CAP_PI to read and write 'usermodehelper_inheritable'.
      
      This seems to be a completely unnecessary indirection, since we could
      instead just use the pointers themselves, and never have to do any "if
      this then that" kind of logic.
      
      So just get rid of the fake pointer values, and use the real pointer
      values instead.

      i2c: Disable I2C_APPLE when I2C_PASEMI is a builtin · a76d19e6
      Benjamin Gray authored
      The ppc64le_allmodconfig sets I2C_PASEMI=y and leaves COMPILE_TEST to
      default to y and I2C_APPLE to default to m, running into a known
      incompatible configuration that breaks the build [1]. Specifically,
      a common dependency (i2c-pasemi-core.o in this case) cannot be used by
      both builtin and module consumers.
      
      Disable I2C_APPLE when I2C_PASEMI is a builtin to prevent this.

      Linus Torvalds authored
      Pull more s390 updates from Heiko Carstens:
      
       - Add empty command line parameter handling stubs to kernel for all
         command line parameters which are handled in the decompressor. This
         avoids invalid "Unknown kernel command line parameters" messages from
         the kernel, and also avoids that these will be incorrectly passed to
         user space. This caused already confusion, therefore add the empty
         stubs
      
       - Add missing phys_to_virt() handling to machine check handler
      
       - Introduce and use a union to be used for zcrypt inline assemblies.
         This makes sure that only a register wide member of the union is
         passed as input and output parameter to inline assemblies, while
         usual C code uses other members of the union to access bit fields of
         it
      
       - Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to
         atomically read a 128-bit value from memory. This replaces the
         (mis-)use of the 128-bit cmpxchg operation to do the same in cpum_sf
         code. Currently gcc does not generate the used lpq instruction if
         __READ_ONCE() is used for aligned 128-bit accesses, therefore use
         this s390 specific helper
      
       - Simplify machine check handler code if a task needs to be killed
         because of e.g. register corruption due to a machine malfunction
      
       - Perform CPU reset to clear pending interrupts and TLB entries on an
         already stopped target CPU before delegating work to it
      
       - Generate arch/s390/boot/vmlinux.map link map for the decompressor,
         when CONFIG_VMLINUX_MAP is enabled for debugging purposes
      
       - Fix segment type handling for dcssblk devices. It incorrectly always
         returned type "READ/WRITE" even for read-only segements, which can
         result in a kernel panic if somebody tries to write to a read-only
         device
      
       - Sort config S390 select list again
