This is a big fat pile of magic numbers. We also have nice macros for a
non-zero number of these, like:
#define MXCSR_DEFAULT 0x1f80
I understand that this probably _works_ as-is, but it doesn't look very
friendly if someone else needs to go hack on it.
APM documents the default value for the AP following the RESET or INIT,
I will define macros and use them accordingly.
thx
