Now I'm more confused. I have two separeate questions:

a) Is the justr-added update-n_high_memory-node-state-for-memory-hotadd-fix.patch
still needed?

b) Which patch in 2.6.22-rc4-mm1 does
update-n_high_memory-node-state-for-memory-hotadd.patch fix? In other
words, into which patch should I fold
update-n_high_memory-node-state-for-memory-hotadd.patch prior to sending
to Linus?

(I (usually) get to work this out for myself. Sometimes it is painful).

Generally, if people tell me which patch-in-mm their patch is fixing,
it really helps. Adrian does this all the time.

Thanks.
