      Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm · 9a8e5d41
      Linus Torvalds authored
      Pull ARM fixes from Russell King:
       "Nothing too disasterous, the biggest thing being the removal of the
        regulator support for vcore in the AMBA driver; only one SoC was using
        this and it got broken during the last merge window, which then
        started causing problems for other people.  Mutual agreement was
        reached for it to be removed."

      x86-32: fix up strncpy_from_user() sign error · 12e993b8
      Linus Torvalds authored
      The 'max' range needs to be unsigned, since the size of the user address
      space is bigger than 2GB.
      
      We know that 'count' is positive in 'long' (that is checked in the
      caller), so we will truncate 'max' down to something that fits in a
      signed long, but before we actually do that, that comparison needs to be
      done in unsigned.
      
      Bug introduced in commit 92ae03f2
      
       ("x86: merge 32/64-bit versions of
      'strncpy_from_user()' and speed it up").  On x86-64 you can't trigger
      this, since the user address space is much smaller than 63 bits, and on
      x86-32 it works in practice, since you would seldom hit the strncpy
      limits anyway.
      
      I had actually tested the corner-cases, I had only tested them on
      x86-64.  Besides, I had only worried about the case of a pointer *close*
      to the end of the address space, rather than really far away from it ;)
      
      This also changes the "we hit the user-specified maximum" to return
      'res', for the trivial reason that gcc seems to generate better code
      that way.  'res' and 'count' are the same in that case, so it really
      doesn't matter which one we return.
