ecf6279f00 - Complete the vm object locking in vm_pageout_object_deactivate_pages().
- Change vm_pageout_object_deactivate_pages()'s first parameter from a
   vm_map_t to a pmap_t.
 - Change vm_pageout_object_deactivate_pages()'s and
   vm_pageout_map_deactivate_pages()'s last parameter from a vm_pindex_t
   to a long.  Since the number of pages in an address space doesn't
   require 64 bits on an i386, vm_pindex_t is overkill.

6745e78cee Don't unconditionally reset the hardware debug registers in cpu_exit(),
reset them only if they were previously in use.  Unconditionally
resetting the registers wipes them out frequently, which interferes

79a5874541 Testing VLANs with the new 8139C+ chip (which does hardware tag
insertion and extraction) has revealed two bugs:

- In vlan_start(), we're supposed to check the underlying interface to
  see if it has the IFCAP_VLAN_HWTAGGING cabability set and, if so, set
  things up for the VLAN_OUTPUT_TAG() routine. However the code checks
  ifp->if_capabilities, which is the vlan pseudo-interface's capabilities
  when it should be checking p->if_capabilities, which relates to the
  underlying physical interface. Change ifp->if_capabilities to
  p->if_capabilities so this works.

- In vlan_input(), we have to extract the 16-bit tag value from the
  received frame and use it to figure out which vlan interface gets
  the frame. The code that we use to track down the desired vlan
  pseudo-interface is:

       for (ifv = LIST_FIRST(&ifv_list); ifv != NULL;
            ifv = LIST_NEXT(ifv, ifv_list))
                if (ifp == ifv->ifv_p && tag == ifv->ifv_tag)
                        break;

  The problem is that 'tag' is not computed consistently. In the case
  where the interface supports hardware VLAN tag extraction and calls
  VLAN_INPUT_TAG(), we do this:

                tag = *(u_int*)(mtag+1);

  But in the software emulation case, we do this

                tag = EVL_VLANOFTAG(ntohs(evl->evl_tag));

  The problem here is the EVL_VLANOFTAG() macro is only ever applied
  in this one case. It's never applied to ifv->ifv_tag or anwhere else.
  We must be consistent: either it's applied everywhere or nowhere.
  To see how this can be a problem, do something like
  ifconfig vlan0 vlan 12345 vlandev foo0 and observe the results.

  I'm not quite sure what the right thing is to do here. Neither the
  vlan(4) nor ifconfig(8) man pages suggest which way to go. For now,
  I've removed this use of EVL_VLANOFTAG() so that the tag will match
  correctly in all cases. I will not get upset if somebody makes a
  compelling argument for using EVL_VLANOFTAG() everywhere instead,
  as long as the use is consistent.

290245ea4c Don't call malloc() and free() while in the debugger and unwinding
to get a stacktrace. This does not work even with M_NOWAIT when we
have WITNESS and is generally a bad idea (pointed out by bde@). We
allocate an 8K heap for use by the unwinder when ddb is active. A
stack trace roughly takes up half of that in any case, so we have
some room for complex unwind situations. We don't want to waste too
much space though. Due to the nature of unwinding, we don't worry
too much about fragmentation or performance of unwinding while in
the debugger. For now we have our own heap management, but we may
be able to leverage from existing code at some later time.

While here:
o  Make sure we actually free the unwind environment after unwinding.
   This fixes a memory leak.
o  Replace Doug's license with mine in unwind.c and unwind.h. Both
   files don't have much, if any, of Doug's code left since the EPC
   syscall overhaul and the import of the unwinder.
o  Remove dead code.
o  Replace M_NOWAIT with M_WAITOK for all remaining malloc() calls.

1f78f902a8 Background: pmap_object_init_pt() premaps the pages of a object in
order to avoid the overhead of later page faults.  In general, it
implements two cases: one for vnode-backed objects and one for
device-backed objects.  Only the device-backed case is really
machine-dependent, belonging in the pmap.

This commit moves the vnode-backed case into the (relatively) new
function vm_map_pmap_enter().  On amd64 and i386, this commit only
amounts to code rearrangement.  On alpha and ia64, the new machine
independent (MI) implementation of the vnode case is smaller and more
efficient than their pmap-based implementations.  (The MI
implementation takes advantage of the fact that objects in -CURRENT
are ordered collections of pages.)  On sparc64, pmap_object_init_pt()
hadn't (yet) been implemented.

c197abc49a Signals sent specifically to a particular thread must
be delivered to that thread, regardless of whether it
has it masked or not.

Previously, if the targeted thread had the signal masked,
it would be put on the processes' siglist. If
another thread has the signal umasked or unmasks it before
the target, then the thread it was intended for would never
receive it.

This patch attempts to solve the problem by requiring callers
of tdsignal() to say whether the signal is for the thread or
for the process. If it is for the process, then normal processing
occurs and any thread that has it unmasked can receive it.
But if it is destined for a specific thread, it is put on
that thread's pending list regardless of whether it is currently
masked or not.

The new behaviour still needs more work, though.  If the signal
is reposted for some reason it is always posted back to the
thread that handled it because the information regarding the
target of the signal has been lost by then.

fa4b32fa80 All current uses of pci_set_powerstate are bogus, at least in theory.
However, they are presently necessary due to bigger bogusness in the
pci bus layer not doing the right thing on suspend/resume or on
initial device probe.  This is exactly the sort of thing that the
BURN_BRIDGES option was invented for.  Mark all of them as
BURN_BRIDGES.  As soon as I have the powerstate stuff properly
integrated into the pci bus code, I intend to remove all these
workarounds.
