Avoid non constant memory model uses in libatomic · 94f3ccc8

Andi Kleen authored 12 years ago

x86 ends up using non constant memory models for some of the libatomic
functions. These all end up as __ATOMIC_SEQ_CST. Just use this
directly. This avoids a new warning for non constant memory
models, which broke the bootstrap with -Werror

Passed bootstrap and test on x86_64-linux.
