      drm/bochs: make structure bochs_bo_driver static · f42bd946
      Colin Ian King authored
      The structure bochs_bo_driver is local to the source and does not need to
      be in global scope, so make it static.
      
      Cleans up sparse warning:
      drivers/gpu/drm/bochs/bochs_mm.c:197:22: warning: symbol 'bochs_bo_driver'
      was not declared. Should it be static?

      unify {de,}mangle_poll(), get rid of kernel-side POLL... · 7a163b21
      Al Viro authored
      except, again, POLLFREE and POLL_BUSY_LOOP.
      
      With this, we finally get to the promised end result:
      
       - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any
         stray instances of ->poll() still using those will be caught by
         sparse.
      
       - eventpoll.c and select.c warning-free wrt __poll_t
      
       - no more kernel-side definitions of POLL... - userland ones are
         visible through the entire kernel (and used pretty much only for
         mangle/demangle)
      
       - same behavior as after the first series (i.e. sparc et.al. epoll(2)
         working correctly).

      vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
      Linus Torvalds authored
      This is the mindless scripted replacement of kernel use of POLL*
      variables as described by Al, done by this script:
      
          for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
              L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
              for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
          done
      
      with de-mangling cleanups yet to come.
      
      NOTE! On almost all architectures, the EPOLL* constants have the same
      values as the POLL* constants do.  But they keyword here is "almost".
      For various bad reasons they aren't the same, and epoll() doesn't
      actually work quite correctly in some cases due to this on Sparc et al.
      
      The next patch from Al will sort out the final differences, and we
      should be all done.

      Pull more poll annotation updates from Al Viro:
       "This is preparation to solving the problems you've mentioned in the
        original poll series.
      
        After this series, the kernel is ready for running
      
            for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
                  L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`

            done
      
        as a for bulk search-and-replace.
      
        After that, the kernel is ready to apply the patch to unify
        {de,}mangle_poll(), and then get rid of kernel-side POLL... uses
        entirely, and we should be all done with that stuff.
      
        Basically, that's what you suggested wrt KPOLL..., except that we can
        use EPOLL... instead - they already are arch-independent (and equal to
        what is currently kernel-side POLL...).
      
        After the preparations (in this series) switch to returning EPOLL...
        from ->poll() instances is completely mechanical and kernel-side
        POLL... can go away. The last step (killing kernel-side POLL... and
        unifying {de,}mangle_poll() has to be done after the
        search-and-replace job, since we need userland-side POLL... for
        unified {de,}mangle_poll(), thus the cherry-pick at the last step.
      
        After that we will have:
      
         - POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of
           ->poll() still using those will be caught by sparse.
      
         - eventpoll.c and select.c warning-free wrt __poll_t
      
         - no more kernel-side definitions of POLL... - userland ones are
           visible through the entire kernel (and used pretty much only for
           mangle/demangle)
      
         - same behavior as after the first series (i.e. sparc et.al. epoll(2)
           working correctly)"

      xtensa: fix build with KASAN · f8d0cbf2
      Max Filippov authored
      The commit 917538e2 ("kasan: clean up KASAN_SHADOW_SCALE_SHIFT
      usage") removed KASAN_SHADOW_SCALE_SHIFT definition from
      include/linux/kasan.h and added it to architecture-specific headers,
      except for xtensa. This broke the xtensa build with KASAN enabled.
      Define KASAN_SHADOW_SCALE_SHIFT in arch/xtensa/include/asm/kasan.h

      nios2: dts: Remove leading 0x and 0s from bindings notation · 5d13c731
      Mathieu Malaterre authored
      Improve the DTS files by removing all the leading "0x" and zeros to fix the
      following dtc warnings:
      
      Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
      
      and
      
      Warning (unit_address_format): Node /XXX unit name should not have leading 0s
      
      Converted using the following command:
      
      find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} +
      
      For simplicity, two sed expressions were used to solve each warnings separately.
      
      To make the regex expression more robust a few other issues were resolved,
      namely setting unit-address to lower case, and adding a whitespace before the
      the opening curly brace:
