[PATCH] x86_64: inline function prefix with __always_inline in vsyscall

Browse source 
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.
