Sönke Holz 6fa8165d91 Kernel/MM: Use same memory type for zeroing pages as the actual mapping ...

On some architectures like ARM, using mismatched memory types for
different aliases of the same physical memory can lead to unexpected
behavior.

Flushing the data cache and using appropriate memory barriers might be
enough, but should have worse performance.
