[PATCH v2 0/1] ARM: signal: sigreturn_codes should be endian neutral to work in BE8

[Victor Kamensky]

This is second version of patch that fixes rt_sig* ltp failures
in case of big endian V7 kernel. It make sigreturn_codes snippets
endian neutral. In this version of the patch problem is fixed by
using separate .S file with snippets written with regular asm
mnemonic. With such change compiler/linker take care of all needed
byteswaps in case of BE8 mode.

This approach was suggested on the following thread:

  http://lists.infradead.org/pipermail/linux-arm-kernel/2013-August/191543.html

Changes were tested on V7 in both BE and LE modes

Changes from v1:
  Use separate .S file rather than <asm/opcodes.h> instruction
  byteswaping macros
