Since kernel v5.8, __vmalloc() does not take protection bits as
PROT_KERNEL is now wired in. Therefore we cannot disable the cache for
the UMM segment via the allocation call directly anymore.

This said, we don't support any CPU architecture exhibiting cache
aliasing braindamage anymore either (was armv4/v5), so let's convert
to the new __vmalloc() call format without bothering for cache
settings.
