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.htm...
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
