Adding LKML to CC
Remove definitions of FASTCALL/fastcall from linkage_32 as compiled with
-regparm=3 by default since 2.6.20 and should no longer be needed.
CONFIG X86_64 and CONFIG_X86_ALIGNMENT_16 are mutually exclusive as found
in Kconfig.cpu so it should be fine to test them separately.

I'm not sure if the definition of asmlinkage and prevent_tail_call can be
omitted as well and let the linux/linkage.h version get picked up instead.
Smarter people than I will have to figure that out.
