Log Message:
Pull up following revision(s) (requested by riastradh in ticket #245):
sys/arch/x86/x86/fpu.c: revision 1.86
x86/fpu: Align savefpu to 64 bytes in fpuinit_mxcsr_mask.
16 bytes is not enough.
(Is this why it never worked on Xen some years back? Got lucky and
accidentally had 64-byte alignment on native x86, but not in the call
stack in Xen?)
