Linux-2.6.12-rc2v2.6.12-rc2

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!

+numa_hit                        A process wanted to allocate memory from this node,

+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.
