Aoi Shinkai	4c7c997886	sh: Fix sh4a llsc-based cmpxchg() ... This fixes up a typo in the ll/sc based cmpxchg code which apparently wasn't getting a lot of testing due to the swapped old/new pair. With that fixed up, the ll/sc code also starts using it and provides its own atomic_add_unless().

Matt Fleming	42990701f9	sh: Relax inline assembly constraints ... When dereferencing the memory address contained in a register and modifying the value at that memory address, the register should not be listed in the inline asm outputs. The value at the memory address is an output (which is taken care of with the "memory" clobber), not the register.
