alas, I did not.  doh.

chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.

thorpej 15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.

msaitoh c090c1cfe5 temporary fix a serious pmap problem with dummy PMAP_{MAP,UNMAP}_POOLPAGE(). 
To fix correctly, set IOM_RAM_BEGIN with P0 addr instead of P1 addr and
fix machdep.c and pmap.c.

thorpej ef2315d256 Rewrite how mod/ref emulation is done. In particular, make 
modified attribute checking actually work.  Previously, a
page could be reported as modified even if it wasn't!  This
is very bad, and e.g. caused the VM system to attempt to
"clean" pages of read-only files.

Only lip-services is paid to referenced attribute emulation.
This could be improved.

itojun 65363da25e Merge in NetBSD/sh3 from cvs.kame.net repository. 
Tree structure:
- sys/arch/sh3: sh3 generic code
	As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
