I didn't, but I do now.

list-based anti-fragmentation
o http://www.csn.ul.ie/~mel/projects/patches/brokenout/mbuddy/v22
o Full patch is called full-mbuddy-v22.diff

zone-based anti-fragmentation
o http://www.csn.ul.ie/~mel/projects/patches/brokenout/zbuddy/v5
o Full patch is called zbuddy-v5-full.diff

In either directory, only the files with the extension .patch are applied
and they are applied in lexical order, so this works

for i in `ls ~/patches/brokenout/zbuddy/v5/*.patch`; do
  patch -p1 < $i
done

The note that is posed with a patch is in the .mail file.

I would. While I currently have access to the machines needed to
cross-compile, I do not have any automated mechanism setup for
anti-fragmentation yet so I only test ppc64 and x86. Greater coverage
would be ideal.

I'd appreciate it. However, to be clear, the patches I am working on are
for anti-fragmentation which will be of benefit to memory hotplug and for
huge tlb. For the memory hotplug patches and the -mhp tree, Dave Hansen is
the man to talk to.

Thanks a lot.
