Don't bother printing vm_swrss of a process, the current uvm accounting
logic never sets this value.

Reimplement uvm/uvm_map.

vmmap is designed to perform address space randomized allocations,
without letting fragmentation of the address space go through the roof.

Some highlights:
- kernel address space randomization
- proper implementation of guardpages
- roughly 10% system time reduction during kernel build

Tested by alot of people on tech@ and developers.
Theo's machines are still happy.

BRKSIZ is the right constant now, so I don't get lots of teeny tiny heaps
mixed up in my address space.

Switch back from KERN_PROC2/kinfo_proc2 to KERN_PROC/kinfo_proc now

Avoid using NULL in non-pointer contexts: use 0 for integer values and '\0'
for chars.

Remove portalfs.

While it is a terribly cool idea, it's just awful and since noone has stepped
up to the plate to keep it up with the current vop state, retire it to the

Namecache revamp.

This eliminates the large single namecache hash table, and implements
the name cache as a global lru of entires, and a redblack tree in each
vnode. It makes cache_purge actually purge the namecache entries associated
with a vnode when a vnode is recycled (very important for later on actually being
able to resize the vnode pool)

This commit does #if 0 out a bunch of procmap code that was
already broken before this change, but needs to be redone completely.

Tested by many, including in thib's nfs test setup.

No longer consider kernel pointers invalid if pointing under the kernel
load address (hello, PMAP_DIRECT architectures). Makes procmap walk the
kernel name cache correctly.

Define a new flag, UVM_FLAG_HOLE, for uvm_map to create a vm_map_entry of
a new etype, UVM_ET_HOLE, meaning it has no backend.

UVM_ET_HOLE entries (which should be created as UVM_PROT_NONE and with
UVM_FLAG_NOMERGE and UVM_FLAG_HOLE) are skipped in uvm_unmap_remove(), so
that pmap_{k,}remove() is not called on the entry.

This is intended to save time, and behave better, on pmaps with MMU holes
at process exit time.
