Uros Bizjak ad0a2e4c2f locking/atomic, xen: Use sync_try_cmpxchg() instead of sync_cmpxchg() ... Use sync_try_cmpxchg() instead of sync_cmpxchg(*ptr, old, new) == old in clear_masked_cond(), clear_linked() and gnttab_end_foreign_access_ref_v1(). x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg), improving the cmpxchg loop in gnttab_end_foreign_access_ref_v1() from: 174: eb 0e jmp 184 <...> 176: 89 d0 mov %edx,%eax 178: f0 66 0f b1 31 lock cmpxchg %si,(%rcx) 17d: 66 39 c2 cmp %ax,%dx 180: 74 11 je 193 <...> 182: 89 c2 mov %eax,%edx 184: 89 d6 mov %edx,%esi 186: 66 83 e6 18 and $0x18,%si 18a: 74 ea je 176 <...> to: 614: 89 c1 mov %eax,%ecx 616: 66 83 e1 18 and $0x18,%cx 61a: 75 11 jne 62d <...> 61c: f0 66 0f b1 0a lock cmpxchg %cx,(%rdx) 621: 75 f1 jne 614 <...> No functional change intended.
