| 2016-07-31 | sh: cmpxchg: fix a bit shift bug in big_endian os | Pan Xinhui | |
| Correct bitoff in big endian OS. Current code works correctly for 1 byte but not for 2 bytes. Fixes: 3226aad81aa6 ("sh: support 1 and 2 byte xchg") Signed-off-by: Pan Xinhui <xinhui.pan@linux.vnet.ibm.com> Acked-by: Michael S.

| 2016-01-12 | sh: move xchg_cmpxchg to a header by itself | Michael S. Tsirkin | |
| Looks like future sh variants will support a 4-byte cas which will be used to implement 1 and 2 byte xchg. This is exactly what we do for llsc now, move the portable part of the code into a separate header so it's easy to reuse. Suggested-by: Rich Felker <dalias@libc.org> Signed-off-by: Michael S.
