David S. Miller	0f58189d4a	sparc64: Make lock backoff really a NOP on UP builds. ... As noticed by Mikulas Patocka, the backoff macros don't completely nop out for UP builds, we still get a branch always and a delay slot nop. Fix this by making the branch to the backoff spin loop selective, then we can nop out the spin loop completely. Signed-off-by: David S. Miller <davem@davemloft.net>	2010-08-18 22:53:26 -07:00
Mikulas Patocka	6ec274750c	sparc64: simple microoptimizations for atomic functions ... Simple microoptimizations for sparc64 atomic functions: Save one instruction by using a delay slot. Use %g1 instead of %g7, because %g1 is written earlier. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>	2010-08-18 22:51:08 -07:00
