Raw Normal View History

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!

/*
* I-Cache snoops remote store. This only matters on SMP. Some multiprocessors

* D-cache all the way back to whever the I-cache does refills from, so the
* I-cache has a chance to see the new data at all. Then we have to flush the
* I-cache also.
* Note we may have been rescheduled and may no longer be running on the CPU
