dbe5213b11 Split arch/sparc/dev/amd7930.c into: 
* MI sys/dev/ic/{am7930.c,am7930var.h} chipset driver
  * sparc frontend.
Presere revision history (this time).

TODO: bus.h'ify,  and padded register mappings.

b40ead2c73 Split sparc am7930 driver into sparc attach and "MI" sys/dev/ic/am7930 
chipset driver.  Needs bus'ifying and  register-access.

1fbd0b3749 GC the unused `physadr' type, which was not able to hold a complete physical 
address on 2 architectures anyhow.  Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
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.

6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be 
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

e615541de9 Maintain far more complete state in the PV lists on the cacheability of pages, 
using separate flag bits for mappings that were requested to be not
cacheable and uncacheable pages due to incongruent aliases.

This avoids inadvertently turning on the cache-enable bits when removing
one of multiple virtual address mappings to the same page. Reading
from /dev/mem could do this to arbitrary pages.
