Subject: disable highpte in rmap kernels
Date: Tue, 23 Jul 2002 15:45:42 -0700 [thread overview]
Message-ID: <61060000.1027464342@flay> (raw)
highpte doesn't work with rmap at the moment, and causes users
to get panics that aren't trivially obvious what is causing them.
I vote we disable it until it works .... totally untested patch below ...
does this look sane to people? Seems trivial enough that even I
couldn't get it wrong, but .... ;-)
