Subject: x86_64: x86_64 - Use non locked version for local_cmpxchg()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bdda1561ffda764583a295229db66d94cf6038a3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86_64: x86_64 - Use non locked version for local_cmpxchg()

local_cmpxchg() should not use any LOCK prefix.  This change probably
got lost in the move to cmpxchg.h.
