[PATCH] x86_64: inline function prefix with __always_inline in vsyscall
In vsyscall function do_vgettimeofday(), some functions are declared as inlined, which is a hint for gcc to compile the function inlined but it not forced. Sometimes compiler does not compile the function as inlined, so here inline is replaced by __always_inline prefix. It does not happen in gcc compiler actually, but it possibly happens.
