Numa policy hit/miss statistics
/sys/devices/system/node/node*/numastat
All units are pages. Hugepages have separate counters.
numa_hit A process wanted to allocate memory from this node,
and succeeded.
numa_miss A process wanted to allocate memory from this node,
but ended up with memory from another.
numa_foreign A process wanted to allocate on another node,
but ended up with memory from this one.
local_node A process ran on this node and got memory from it.
other_node A process ran on this node and got memory from another node.
interleave_hit Interleaving wanted to allocate from this node
and succeeded.
For easier reading you can use the numastat utility from the numactl package
(ftp://ftp.suse.com/pub/people/ak/numa/numactl*). Note that it only works
well right now on machines with a small number of CPUs.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
