e1b25b7bd6 Make spec_write() process errors and return them, otherwise we don't even 
notice things like hitting the end of a partition or device.  (To be sure,
writes to block special files are rare, but as long as we support them...)

fcf7a78c02 Workaropund fix for PR #5239 from <minoura@kw.netlaputa.ne.jp>: 
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.

961f0708b1 - Rename nqnfs_vop_lease_check() to genfs_lease_check(). If NFSSERVER is 
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).

651b44e211 Rework the way kernel include files are installed. In the new method, 
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.

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.

f9777e4a1c Fix the procfs hole described on current-users, similar to a fix for 
FreeBSD by Sean Eric Fagan, but a bit different.  This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):

	(1) it's not owned by you, or is set-id on exec (unless
	    you're root), or

	(2) it's init, which controls the security level of the
	    entire system, and the system was not compiled with
	    permanently insecure mode turned on.
