Remove src/sys/arch{pmax/pmax,pica/pica}cpu_exec.c; no significant differences,
or for which the Pica port is an older revision of the pmax branch. A merged version with the NetBSD/pmax revision history is in mips/mips/. cpu_exec.c elf.c mem.c process_machdep.c

* Functions to be implemented here are:
|

*
|

* process_read_regs(proc, regs)
|
||||
* Get the current user-visible register set from the process
|
||||
* and copy it into the regs structure (<machine/reg.h>).
|
||||
* The process is stopped at the time read_regs is called.
|
||||
*
|
||||
* process_write_regs(proc, regs)
|
||||
* Update the current register set from the passed in regs
|
||||
* structure. Take care to avoid clobbering special CPU
|
||||
* registers or privileged bits in the PSL.
|
||||
* The process is stopped at the time write_regs is called.
|
||||
*
|
||||
* process_sstep(proc)
|
||||
* Arrange for the process to trap after executing a single instruction.
|
||||
*
|
||||
* process_set_pc(proc)
|
||||
* Set the process's program counter.
