fbbaea5f90 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

35780dc21a 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.

9b295c2fd9 - 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.)

4ab080249a 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.

f77d7b9449 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.

ea94acfaa6 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.)
