Kevin, Olof,

Please pull highbank updates for 3.12.

There's one trivial core ARM code change in the series to allow a DMA_ZONE size of 4GB. I believe this should not conflict with Russell's DMA mask series.

This one seems to have broken the AMBA PL08x DMA driver, and is still objected to by Russell, so I'll drop this one for now.

The rest look OK and I can pull them if the rest are OK without the objectionable one. Let me know if that's OK, or you prefer to wait for resolution.

Exynos does the same selection, but I guess it is not multi-platform though and doesn't select ARM_AMBA.

OK, with 2 of the 5 patches still having problems/objections, and the one causing a new build warning, I've backed out this branch from for-next.

Could you just respin a branch with the first 3 patches and the fix folded in? I know I requested the opposite on IRC, but having a new pull request allows me to include your signed tag on the whole bit instead of me having to manually massage the branch and merge without a signed tag.

Thanks,

Kevin

Wow, that went well. Sorry about that.

Will do. I've got another patch to add and will see if I can get pl081 issue sorted out in the next few days.
