* | sh: support 1 and 2 byte xchg | Michael S. Tsirkin | 2016-01-12 |
| | | | | | | | | | | | | | 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. Tsirkin <mst@redhat.com> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> | ||

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. 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.
