address on 2 architectures anyhow.  Also, move the definition of the `label_t'

setjmp()/longjmp() implementations.

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.

5e91ce6ef1 initial import of the new virtual memory system, UVM, into -current. 
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 sparc portion.

8a5023e38c After writing to the IOMMU flush registers, read something back from 
IOMMU control space to a flush register to drain internal write buffers (?).
This avoids utter lossage on some machines (SS4s & SS5s) where our caller
would see some of its local (`%lx') registers trashed. This is probably
caused by a silicon bug allowing interference on internal data paths..
