4da47b2fec Add __elfN(dump_thread). This function is called from __elfN(coredump) 
to allow dumping per-thread machine specific notes. On ia64 we use this
function to flush the dirty registers onto the backingstore before we
write out the PRSTATUS notes.

Tested on: alpha, amd64, i386, ia64 & sparc64
Not tested on: arm, powerpc

check still needs implementation on arm.

684a62b7bf - Push down the acquisition and release of Giant into pmap_enter_quick() 
on those architectures without pmap locking.
 - Eliminate the acquisition and release of Giant in vm_map_pmap_enter().

9f1b87f106 Instead of calling ia32_pause() conditionally on __i386__ or __amd64__ 
being defined, define and use a new MD macro, cpu_spinwait().  It only
expands to something on i386 and amd64, so the compiled code should be
identical.

9bb0e06861 - Push down the acquisition and release of Giant into pmap_protect() on 
those architectures without pmap locking.
 - Eliminate the acquisition and release of Giant from vm_map_protect().

(Translation: mprotect(2) runs to completion without touching Giant on
alpha, amd64, i386 and ia64.)

1a8cfbc450 Pass a thread argument into cpu_critical_{enter,exit}() rather than 
dereference curthread.  It is called only from critical_{enter,exit}(),
which already dereferences curthread.  This doesn't seem to affect SMP
performance in my benchmarks, but improves MySQL transaction throughput
by about 1% on UP on my Xeon.

fd32d93b97 Unify db_stack_trace_cmd(). All it did was look up the thread given 
the thread ID and call db_trace_thread().
Since arm has all the logic in db_stack_trace_cmd(), rename the
new DB_COMMAND function to db_stack_trace to avoid conflicts on
arm.
While here, have db_stack_trace parse its own arguments so that
we can use a more natural radix for IDs. If the ID is not a thread
ID, or more precisely when no thread exists with the ID, try if
there's a process with that ID and return the first thread in it.
This makes it easier to print stack traces from the ps output.

ce8da3091f Push down the acquisition and release of the page queues lock into 
pmap_remove_pages().  (The implementation of pmap_remove_pages() is
optional.  If pmap_remove_pages() is unimplemented, the acquisition and
release of the page queues lock is unnecessary.)

Remove spl calls from the alpha, arm, and ia64 pmap_remove_pages().
