Arnd Bergmann ec7633de40 sparc: mark __arch_xchg() as __always_inline ... An otherwise correct change to the atomic operations uncovered an existing bug in the sparc __arch_xchg() function, which is calls __xchg_called_with_bad_pointer() when its arguments are unknown at compile time: ERROR: modpost: "__xchg_called_with_bad_pointer" [lib/atomic64_test.ko] undefined! This now happens because gcc determines that it's better to not inline the function. Avoid this by just marking the function as __always_inline to force the compiler to do the right thing here.
