      crypto: kpp - Count error stats differently · e2950bf1
      Herbert Xu authored
      Move all stat code specific to kpp into the kpp code.
      
      While we're at it, change the stats so that bytes and counts
      are always incremented even in case of error.  This allows the
      reference counting to be removed as we can now increment the
      counters prior to the operation.
      
      After the operation we simply increase the error count if necessary.
      This is safe as errors can only occur synchronously (or rather,
      the existing code already ignored asynchronous errors which are
      only visible to the callback function).

      crypto: algapi - Move stat reporting into algapi · ed0733ea
      Herbert Xu authored
      The stats code resurrected the unions from the early days of
      kernel crypto.  This patch starts the process of moving them
      out to the individual type structures as we do for everything
      else.
      
      In particular, add a report_stat function to cra_type and call
      that from the stats code if available.  This allows us to move
      the actual code over one-by-one.

      hwrng: xgene - Improve error reporting for problems during .remove() · 0e44db95
      Uwe Kleine-König authored
      Returning an error value in a platform driver's remove callback results in
      a generic error message being emitted by the driver core, but otherwise it
      doesn't make a difference. The device goes away anyhow.
      
      As the driver already emits a better error message than the core, suppress
      the generic error message by returning zero unconditionally.

      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.

         - 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.

      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.
