decoupled from long or int or long long. Define macros in asm.h to facilitate
choosing these on a port by port basis.
* Create <machine/pubassym.h> mechanism to allow jmp_buf structure size
to be calculated at system build time.
* Define _MIPS_BSD_SIM macro which specifies what calling style is appropritae
for the architecture. For 64-bit oriented systems set the Status Register
to allow 64-bit instructions.
* Remove UADDR related macros because kernel U structure is now mapped
normally.
* Separate cpu.h into cpu.h and cpuarch.h to keep things neat.
* Add support for QED 52xx processors
undone by rev 1.7:
>redo pmax/include/reg.h
>so that the definitions needed by locore.S are in a separate file,
>pmax/include/regnum.h.
* Add explicit `#include <mips/regnum.h>' where symbolic offsets
into a mips trapframe or struct reg are used..
* define PT_GETREGS and PT_SETREGS in pmax/include/ptrace.h
* Flesh out the stubs in pmax/pmax/process_machdep.c to handle
those requests.
* Now that "struct reg" is actually used, remove the bogus
#ifdef LANGUAGE_C around its definition, and redo pmax/include/reg.h
so that the definitions needed by locore.S are in a separate file,
pmax/include/regnum.h.
* update locore.S to match.
