Thanks for doing these. Am I correct in assuming we don't need to consider these fixes urgent or critical? Only the first looks like it could be serious, and the x86 fix for that is 3 years old and ARM has gone without it all this time. So I'm guessing it's fine to wait for the normal development process and deal with it after the about to open merge window is completed? If so, I propose that I put the patches in a branch for Russell to pull later (unless he pipes up with objections or says otherwise). Meantime I'll investigate the kprobes test failures I see (which actually looks like cache/TLB issues and not test code problems after all). BTW, I added the ARM kernel list to the CC. I spotted you didn't add it to you patch postings, which means people interested in ARM (other than Russell) wouldn't have seen them. Thanks -- Tixy
