1f04261973 [partially forced commit due to pilot error in earlier commit attempt] 
{set,fill}_{,fp,db}regs() fixup:

 - Add dummy {set,fill}_dbregs() on architectures that don't have them.

 - KSEfy the powerpc versions (struct proc -> struct thread).

 - Some architectures had the prototypes in md_var.h, some in reg.h, and
   some in both; for consistency, move them to reg.h on all platforms.

These functions aren't really MD (the implementation is MD, but the interface
is MI), so they should move to an MI header, but I haven't figured out which
one yet.

5577bd2bca Rework pmap so that it separates the PTE structure from the pv_entry 
structure. This makes it possible to pre-allocate PTEs for the kernel,
which is necessary for a reliable implementation of pmap_kenter(). This
also avoids wasting space (about 48 bytes per page) for kernel mappings
and user mappings of memory-mapped devices.

This also fixes a bug with the previous version where the implementation
required the pv_entry structure to be physically contiguous but did not
enforce this (the structure size was not a power of two). This meant
that the pv_entry free list was quickly corrupted as soon as the system
was even mildly loaded.

3da3249106 Dissociate ptrace from procfs. 
Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested.  Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.

This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().

It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".

fd54558a83 - If we ever do the per-cpu KTR stuff, the index won't be volatile as it 
will be private to each CPU.
- Re-style(9) the globaldata structures.  There really needs to be a MI
  struct pcpu that has a MD struct mdpcpu member at some point.

time.

56f6eed759 Avoid the region used for thread0's trapframe when setting up the stack 
for ia64_init. If we use this area for ia64_init's stack, it ends up
containing garbage which causes cpu_fork to die horribly later.

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

eb30c1c0b9 Rip some well duplicated code out of cpu_wait() and cpu_exit() and move 
it to the MI area.  KSE touched cpu_wait() which had the same change
replicated five ways for each platform.  Now it can just do it once.
The only MD parts seemed to be dealing with fpu state cleanup and things
like vm86 cleanup on x86.  The rest was identical.

XXX: ia64 and powerpc did not have cpu_throw(), so I've put a functional
stub in place.
