0b956d0b8b Implement pmc(9) -- An interface to hardware performance monitoring 
counters.  These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface.  Initially, the Intel XScale
counters are the only ones supported.

bef00d4895 m68k syscall rototill: 
- Switch all m68k-based ports over to __HAVE_SYSCALL_INTERN.
 - Add systrace glue.
 - Define struct mdproc in <m68k/proc.h> instead of <machine/proc.h>.
   (They were all defined exactly the same anyway, other than a couple
   of the MDP_* flags.)

6b030ee036 - define other DEV_ constants that the local port uses. 
- delete cdev_decl(mm) since <sys/conf.h> does it.

07d023a3aa Define ELF32_EHDR_FLAGS_OK()/ELF64_EHDR_FLAGS_OK() and use it 
as an added measure to make sure that we can execute a binary.
These default to (1) if elf_machdep.h does not override them.

On Sun2, ELF32_EHDR_FLAGS_OK() checks for the presense of EF_M68000,
since the 68010 cannot run binaries for the 68020-and-up.

9c3a981460 Just use the stock m68k/elf_machdep.h for now, so that things compile. 
A patch to handle EF_M68000 will be posted shortly.

ARM ports are the only ones that actually have one, and it is about
to change.

the console keyboard is on the parallel interface or zs1.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Reviewed by Jason.

cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).
