Move inappropriate stuff in cpu.h elsewhere:
{s,g}et_intr_mask -> md_var.h
num_tlbentries -> tlb.h
Remove #define clockframe trapframe and fix clock, which was the only place
this was used.
All the rest of this stuff was unused.

used on powerpc64 as well (build scripts, for instance), and the MFS root

This doesn't completely solve things: sysinstall stil needs some
persuasion to deal with a default kernel named GENERIC64.
calls mips_cpu_call via an obfuscated assembler call. Instead, delete
the current cpu_throw, and rename mips_cpu_throw to cpu_throw. This
is nicer to the cache on each context switch (since fixed jumps can be
prefected, while jumps through a register can't). Incidentally, it
also saves about 5 or 6 instructions.

simplecmd() only handles simple commands and function definitions, neither
of which involves the ! keyword. The initial token on entry to simplecmd()
is one of the following: TSEMI, TAND, TOR, TNL, TEOF, TWORD, TRP.
r165114 added that code and that change ignored the same logic
committed in r135772. In addition, data FIFO protection should be
selectively enabled instead of applying to all PCIe devices.
While I'm here add BCM5785 to devices that do not require this
fix.
and remove a buffer overflow:
- Remove the array of per-type dispatch functions. Instead, pass each
structure to a single callback. The callback should check the type of
each table entry to take appropriate action. This matches the behavior
of other table walkers such as for the MP Table and MADT.
- Don't attempt to save an array of string pointers for each structure
entry. Instead, just skip the strings. If this code is reused to
provide a generic SMBIOS table walker in the future we could provide
a method that looks up a specific string N for a given structure record
instead of pre-populating an array of pointers. This fixes a buffer
overflow for structure entries with more than 20 strings.

- Simplify ktrstruct() calling convention by having ktrstruct() use
strlen() rather than requiring the caller to hand-code the length of
constant strings.

- Right now if segments are not writable are not included. Remove this.
- Right now if a segment is mapped with NOCORE the check is not honoured.
Change this by checking the newly added flag, from libutil,
KVME_FLAG_NOCOREDUMP.
Besides that, add a new flag (-f) that forces a 'full' dump of all the
segments excluding just the malformed ones. This might be used very
carefully as, among the reported segments, there could be memory
mapped areas that could be vital to program execution.

The code in question verifies that all register write operations only change
bits that are defined (in the register definition file) for that effected
register. The bug effectively disabled this checking.
o Fix the check by testing the opcode against all supported read ("and" based)
operands.
o Add missing bit definitions to the aic7xxx and aic79xx register definition
files so that the warning (treated as a fatal error) does not spuriously
fire.
