Linux-2.6.12-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!

[PATCH] s390: 64 bit diag250 support Add support for diag 250 access to dasd devices for 64 bit kernels. In addition fix detach/attach for diag disks. The VM control block needs to get recreated by a call to mdsk_init_io.
