Johannes Berg a31e9c4e72 Revert "um: support some of ARCH_HAS_SET_MEMORY" ... This reverts commit 963285b0b4 ("um: support some of ARCH_HAS_SET_MEMORY"), as it turns out that it's not only not working (due to um never using the protection bits in the page tables) but also corrupts the page tables if used on a non-vmalloc page, since um never allocates proper page tables for the 'physmem' in the first place. Fixing all this will take more effort, so for now revert it.
