oops, right, the emergency-pool patch was just a quick hack to check
whether this is the final problem affecting RL highmem systems.

the attached highmem-2.4.2-A0 patch does the jist of your fixes, against
-ac4. Differences: no need to complicate highmem.c with pool-fillup on
bootup. It will get refilled after the first disk-accesses anyway.

i'm unsure about the other changes done by your patch, could you explain
them? Notably the pgalloc-3level.h and fault.c changes. Thanks,
