Which is too much unpageable data. Page tables are meant to be paged.
Yes, but this machine has 178mb of ram which the kernel has to get to
at all times. I can use multi-page page table entries though and with
some of the changes in the 1.3.8* era I should be able to pull it off
and not distrurb the mm generic code.
