We seem to have found the dud patch.  Things should be a little
more stable...

The CONFIG_PREEMPT+SMP problem I was having went away when gcc-2.95.3
was used in place of 2.91.66.  Which is a bit of a problem because
_someone_ has to keep an eye on 2.91.66 compatibility as long as it
continues to be required for sparc builds.

There is a memory corruption problem happening deep in the scsi code
when the hot-n-cold pages patch is present.  Current theory is that
this is a use-after-free problem in scsi, and that the hot-n-cold
pages patch is exposing it because its LIFO page queue will hand
out a page immediately after this cpu freed it.

The workaround is a patch -R of

	page-reservation.patch
	pagevec-hot-cold-hint.patch
	readahead-cold-pages.patch
	hot_cold_pages.patch

in that order.
