Michael S. Tsirkin	3226aad81a	sh: support 1 and 2 byte xchg ... This completes the xchg implementation for sh architecture. Note: The llsc variant is tricky since this only supports 4 byte atomics, the existing implementation of 1 byte xchg is wrong: we need to do a 4 byte cmpxchg and retry if any bytes changed meanwhile. Write this in C for clarity. Suggested-by: Rich Felker <dalias@libc.org> Signed-off-by: Michael S.

Paul Mundt	f15cbe6f1a	sh: migrate to arch/sh/include/ ... This follows the sparc changes a439fe51a1. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
