Thomas Bogendoerfer 11d172c77d MIPS: include: Mark __cmpxchg as __always_inline ...

[ Upstream commit 88356d09904bc606182c625575237269aeece22e ]

Commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING
forcibly") allows compiler to uninline functions marked as 'inline'.
In cace of cmpxchg this would cause to reference function
__cmpxchg_called_with_bad_pointer, which is a error case
for catching bugs and will not happen for correct code, if
__cmpxchg is inlined.
