Shouldn't this be __CPUINT/__CPUINITDATA? That way you could also get rid of things like in x86_64 head.S;

Zwane -- good point. New patch.
P.
Change sysenter_setup to __cpuinit.
Add __CPUINIT & __CPUINITDATA.
Resolve MODPOST warnings similar to:
WARNING: vmlinux - Section mismatch: reference to .init.text:sysenter_setup from
.text between 'identify_cpu' (at offset 0xc040a380) and 'detect_ht'
and
WARNING: vmlinux - Section mismatch: reference to .init.data:vsyscall_int80_end
