[PATCH] shrink zonelists.
Originally from Matt Dobson. I've been running with this for a while
in -dj, with no noticable side-effects.
Matt:
node_zonelists looks like it should really be declared of size
MAX_NR_ZONES, not GFP_ZONEMASK. GFP_ZONEMASK is currently 15, making
node_zonelists an array of 16 elements. The extra zonelists are all
just duplicates of the *real* zonelists, namely the first 3 entries.
Again, if anyone can explain to me why I'm wrong in my thinking, I'd
love to know. There's certainly no way you could bitwise-and something
with any combination of the GFP_DMA and GFP_HIGHMEM flags to refer to
the 12th zonelist or some such! Or am I crazy?
