x86: Fix vsyscall on gcc 4.5 with -Os
commit 124482935fb7fb9303c8a8ab930149c6a93d9910 upstream.
This fixes the -Os breaks with gcc 4.5 bug. rdtsc_barrier needs to be
force inlined, otherwise user space will jump into kernel space and
kill init.
This also addresses http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44129
I believe.
