2a444f81a0 Use VM_ALLOC_NOBUSY to eliminate an unneeded vm_page_wakeup() call and the
synchronization that one entails.

d8a821e8cf Get rid of a lockmgr consumer by making agp(4) use a standard mutex,
since it's always acquiring the lock exclusively.  This was tested
with X on an SMP box, with and without WITNESS.

7ef6ba5d27 Push down the responsibility for zeroing a physical page from the
caller to vm_page_grab().  Although this gives VM_ALLOC_ZERO a
different meaning for vm_page_grab() than for vm_page_alloc(), I feel
such change is necessary to accomplish other goals.  Specifically, I
want to make the PG_ZERO flag immutable between the time it is
allocated by vm_page_alloc() and freed by vm_page_free() or
vm_page_free_zero() to avoid locking overheads.  Once we gave up on
the ability to automatically recognize a zeroed page upon entry to
vm_page_free(), the ability to mutate the PG_ZERO flag became useless.
Instead, I would like to say that "Once a page becomes valid, its
PG_ZERO flag must be ignored."

f246e4a17f - Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
  such abuse isn't really needed.  (And if we do need type information
  associated with a module then we should make it explicit and not
  use hacks.)

fff6062ab6 o Retire vm_page_zero_fill() and vm_page_zero_fill_area(). Ever since
pmap_zero_page() and pmap_zero_page_area() were modified to accept
   a struct vm_page * instead of a physical address, vm_page_zero_fill()
   and vm_page_zero_fill_area() have served no purpose.

2395531439 Introduce a global lock for the vm subsystem (vm_mtx).
vm_mtx does not recurse and is required for most low level
vm operations.

faults can not be taken without holding Giant.

Memory subsystems can now call the base page allocators safely.

Almost all atomic ops were removed as they are covered under the
vm mutex.

Alpha and ia64 now need to catch up to i386's trap handlers.

FFS and NFS have been tested, other filesystems will need minor
changes (grabbing the vm lock when twiddling page properties).
