locked nodes.
Also fix a bug in union_copyup() where a lock on the lower vnode would
only be released if VOP_OPEN didn't fail.
with UVM and seperate I&D-Cache). Mostly by Michael Hitch, but pass struct
proc * instead of the pmap. Reason: said machine will need a method to do
the syncing operation for "curproc", too; this way more code can be shared.
stop null_node_create() from locking the nullfs mountpoint multiple
times. Avoids a guaranteed, repeatably "locking against myself" panic
during mount of a nullfs filesystem. nullfs filesystems are still as
buggy as ever (e.g., see PR# 4907) but this you at least mount them.
not in the kernel, genfs_lease_check() is simply a no-op. This allows
LKM'd file systems to be exported (previously did not work properly
due to a compile-time decision based on -DNFSSERVER).

as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
(1) Fix a typo that caused a NULL pointer deref.
(2) union_copyup() locks the vnode, so unlock it before calling relookup().

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.
(thus causing s_leader to become NULL) by storing the session ID separately
in the session structure. Export the session ID to userspace in the
eproc structure.

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
