only have to sync the I-stream when the mapping is removed or chaged,
and since the I-stream is fetch-only, changing protection bits does
not constitute changing the mapping (the VA->PA translation is still
the same).
being shutdown, then unconfigure the RAID set too. This fixes a number
of issues with doing proper unconfigures/shutdowns of multi-level RAID
sets.
Thanks to Jason Thorpe and Bill Squier for the ideas/suggestions on
how/where to do this, and to Bill Squier for testing.

the kernel to panic since it is recognised as a TGA and the TGA driver
doesn't [yet] know what to do with it.
This patch fixes that by:
o making tgamatch() try to actually figure out what kind
of TGA card is there, rather than simply relying on the
vendor/product ids.
o creating a tga_cnmatch() so that the console code in
arch/alpha/pci/pci_machdep.c can cause the same to occur.
o breaking up some of tga_getdevconfig() into a few different
functions to re-use code that would have been duplicated.
o changed arch/alpha/pci/pci_machdep.c so that it calls out
to tga_cnmatch() if DEVICE_IS_TGA() matches before it decides
to attach the console as a TGA.

be locked before it can be marked as `active' on a processor.
- Require that pmaps other than the kernel pmap be locked when they
are passed to pmap_tlb_shootdown(). This, combined with the locking
protocol tweak, allow us to get a consistent view of `activeness' of
a pmap, which means we can optmize away a lot of TLB shootdown traffic
for user pmaps.
- Borrow an idea from the i386mp branch; use the normal SHOOTDOWN IPI
to deal with hitting the entire TLB, and garbage-collect the TBIA
and TBIAP IPIs.
