61458d7dfa LOCKDEBUG enhancements for non-MP: 
keep a list of locked locks.
use this to print where the lock was locked
when we either go to sleep with a lock held
or try to free a locked lock.

ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

0711fdaf0b fix a locking problem by replacing the call to uvm_kernacc() 
with an inlined version that uses kmem_map instead of kernel_map.

1a8c7604f4 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

66abe4217c Implement an activity log for malloc() and free(), useful for tracking 
down "Data modified on freelist" and "muliple free" problems.

The log is activated by the MALLOCLOG option, and the size of the
event ring buffer is controlable via the MALLOGLOGSIZE option (default
is 100000 entries).

From Chris Demetriou, cleaned up a little by me per suggestions in the
e-mail from Chris that contained the code.

06c209646e handle the case where kmem_malloc() returns NULL in the 'can wait' case. 
Right now, this code just panic()s (same as kmem_malloc() used to do
before, but different message), but in the future it should be modified
to try to reclaim wasted memory.

57b8bdb5c3 Fix a bug where free()ing an already-free block, or even a block that looked 
like it might have already been freed, would cause a crash because of a bad
pointer dereference.  Pointed out by Brian Noble <bnoble@cs.cmu.edu>.

c0cdc0cf04 when printing data modified on the free list: 
(1) do not cast it to (void *), and
	(2) print it as 0x%x, rather than %p.
This is not perfect (because the data being printed is "int32_t"-sized), but
is more correct than printing it as a pointer because the data is _not_ a
pointer, it is data to be printed in hex, and on some systems, pointers are
wider than the data items being printed, which leads to excess and misleading
output.  The only 'right' solution to this is to have a printf specifier
that prints the fixed-sized types the right way, and that's not really
practical.

3d9ffd41f3 make this work sanely on a 64-bit machine. Sacrifices a small bit of 
error checking in the DIAGNOSTIC case.  These changes might be backed out,
if it's decided that MINBUCKET should be 5 (rather than 4) on the alpha.
However, doing that has its own set of nasty consequences.
