The current kernel commandline for ux500 based devices includes hard-coded allocations for things like mali and hwmem, which actually run over lowmem. Here we enable highmem in order to avoid memory corruption errors.

Err what? highmem should make no difference if things are being done correctly.

In other words, your patch description is too vague to understand what the problem is and why you have to force highmem on - and nothing should _require_ highmem.

I think I must have misunderstood some advice which was recently given to me. I'll drop the patch.

Thanks for reviewing.
