Fix following section mismatch warning:
WARNING: vmlinux.o(.text+0xc88c): Section mismatch: reference to
.init.text:trap_init_f00f_bug (between 'init_intel' and 'cpuid4_cache_lookup')
init_intel are __cpuint where trap_init_f00f_bug is __init.
Fixed by declaring trap_init_f00f_bug __cpuinit.
Moved the defintion of trap_init_f00f_bug to the sole user in init.c
so the ugly prototype in intel.c could get killed.
Frank van Maarseveen <[EMAIL PROTECTED]> supplied the .config used
to reproduce the warning.
