Cover letter [PATCH 0/5] ARMv6 and ARMv7 mm fixes

Hi Russell,

I was planning to CC stable for patches 1 ("ARM: cache: ensure MVA is cacheline aligned in flush_kern_dcache_area") and 4 ("ARM: mm: fix racy ASID rollover broadcast on SMP platforms") as these affect existing v6 and v7 cores. The remainder of the patches, although nice to have, only kick in on A15 as far as I'm aware (due to aggressive caching of speculative level 1 entries).

Would it be appropriate to reorder the series then so patches 1 and 4 come first?

I'm not entirely convinced (4) is the best solution yet, but that's mainly becaues I've not thought about it enough yet. 1-3 look fine though.

Ok, thanks for looking at those. I'll put 1-3 and 5 into the patch system since these can be applied irrespective of the other guy. Once you've had a think about 4, I'd be happy to discuss it on the list if you can think of a better way to solve the problem.

I was hoping for some acks/tested-bys before then since these changes affect a lot of platforms and the code is fairly scary.

Yes the patches look scary. I could give it a test on MSM but I'm not even sure that will help much. Why didn't you Cc Russell on these patches?

I do tend to read about 90% of linux-arm-kernel, whether its cc'd to me or not. The cc doesn't really affect whether I read it or not.

I figured as much and it saves me having to remember to remove the CC line when I send to the patch system.

Cheers,

Will
