[PATCH 0/8] x86 signal code cleanups

[Brian Gerst <brgerst@gmail.com>]

The 32-bit signal code has significant differences from 64-bit, and
those are duplicated for native and compat modes.  This patch series
merges the 32-bit code into one file, and does some general cleanups
in the x86 signal code.  There should be no functional changes.

Brian Gerst (8):
  x86/signal: Remove sig parameter from frame setup functions
  x86/signal: Remove sigset_t parameter from frame setup functions
  signal/compat: Remove compat_sigset_t override
  x86: Remove __USER32_DS
  x86/signal: Merge get_sigframe()
  x86/signal: Add ABI prefixes to frame setup functions
  x86/signal/32: Merge native and compat 32-bit signal code
  x86/signal/64: Move 64-bit signal code to its own file
