These are for x86/urgent. This fixes at least one problem that Sasha can trigger using some crazy configuration + Trinity. I can't reproduce the full file of nastiness that he's seeing, but these patches both look legit to me, they fix what look like real bugs, and they seem to help Sasha's tests. Patch 1 is ugly. Feel free to tell me to shove the asm into the entry asm files, although that will involve duplicating it for 32-bit and 64-bit kernels.
