ARC: CONFIG_ARC_MMU_V4

Hi Vineet,

Commit ef680cdc2437 ("ARC: Disable caches in early boot if so configured") landed in linux-next yesterday (ie, next-20140610). It includes two optional tests for CONFIG_ARC_MMU_V4. There's no Kconfig symbol ARC_MMU_V4 in linux-next.

I assume you've got that symbol queued somewhere. Is that correct?

Thanks,

Paul Bolle

My bad - MMU_V4 support is still in works, and not ready for mainline yet. If you wish you could submit a patch to nuke it.

Thx,
-Vineet

There's no Kconfig symbol ARC_MMU_V4 so the checks for CONFIG_ARC_MMU_V4 will always evaluate to false. Remove them.

Entirely untested!

It would be nice if this could be squashed into commit ef680cdc2437 ("ARC: Disable caches in early boot if so configured"). But I guess the ARC tree that is included in linux-next cannot be rebased.
