efbd14c45d mounting a union causes VOP_WHITEOUT to be called on the upper root
vn, with a 0 component.  If the upper fs was a unionfs,
union_whiteout() would deref compnent to get a struct proc, and panic.
struct proc was only being passed to FIXUP, which never used it.  It
turns out this happened a lot.  I ripped most of the unneeded code
out, and left in the few places that really did need the proc handle.

typedef struct pmap *pmap_t there, removing the latter from
pmap3.h and pmap3x.h (so LKMs can use <vm/vm.h>).

b9eaff9db8 when considering attaching compatibility-mode channels, try a quick reset
and see if anything responds.  if nothing (that's attributable to the
PCI IDE controller) responds, then that channel either has no devices on
it or has been disabled (via a non-standard mechanism) by the BIOS.  If nothing
responds, don't map the compat.-mode interrupt or attach the wdc to that
channel, because the BIOS is likely to assign that IRQ to a different PCI
device.  If that happens, the kernel will panic because that device will
try to map the IRQ level-triggered, but the compat interrupt will have been
mapped edge-triggered.  (One possible way around this is to map the compat
interrupt edge-triggered, but it's not clear reading the spec that this
is correct or desirable.)

44650d03a6 Better fix for PR 5113, per discussion with fvdl: now that the vnode locking
interface allow recusive locks, use it instead of the local hack to avoid
recursive locking.

00452b441f Move PTE-related constants here, and make them not depend on a hard-coded
page size (i.e. use the one initialized from the HWRPB at boot time).

Do a bit of cleanup while here, rendering old inherited constants obsolete.

e046925c3a Massive cleanup and partial rewrite of the NetBSD/alpha pmap module.
Major change is that page table page management has been completely
rewritten.  Page tables are now accessed via K0SEG (no more KVA space
wasted on user page tables), and a much larger user address space is
supported.

Many thanks to Chris Demetriou and Ross Harvey for helpful insight and
debugging assistance.

927ec8b012 bug fix: when doing uvm_vnp_sync() actually skip over blocked uvn's so
that we don't try and sync them later.   should get rid of the

occuring during a "make install."
