deb9f8f4b6 (1) Remove old trap definitions, define trap and interrupt handling 
more naturally in terms of way the OSF/1 PALcode delivers traps and
interrupts.  Clean up fault/exception handling code and system entry
points.  Seperate ASTs into a seperate C function.
(2)     Restructure and improve machine check and correctable error
handling based on information in the 2nd Ed. of the Alpha Architecture
Reference Manual.
(3)     Removed unused (and not likely useful) PALcode assembly stubs.

9310a8c8aa don't save and set the USP at every trap entry and exit. It's 
unnecessary, and given that there's no reason to waste time and
add complexity in trap handlers.  This means that code which sets and
uses the USP has to be a bit more careful, but that doesn't happen much.

105697388d Instead of treating the trap/syscall/exception frame like a struct 
containing a substruct (the hardware frame) and an array of registers,
treat it like one big array of registers, for easier and prettier
access.  Update everything to deal with that.

c3a7b67f3d Everything which would be defined here is defined in 
alpha_cpu.h, and this file is no longer necessary for the
Alpha.  However, some machine-independent code (e.g.
/sys/compat/common/kern_exit_43.c) still wants a file with
this name to be around.
