Jan Beulich 8055cdfe68 x86: drop bogus "cc" clobber from __try_cmpxchg_user_asm() ... commit 1df931d95f4dc1c11db1123e85d4e08156e46ef9 upstream. As noted (and fixed) a couple of times in the past, "=@cc<cond>" outputs and clobbering of "cc" don't work well together. The compiler appears to mean to reject such, but doesn't - in its upstream form - quite manage to yet for "cc". Furthermore two similar macros don't clobber "cc", and clobbering "cc" is pointless in asm()-s for x86 anyway - the compiler always assumes status flags to be clobbered there.
