Hi,

Memtest is a simple feature which fills the memory with a given set of
patterns and validates memory contents, if bad memory regions is detected it
reserves them via memblock API. Since memblock API is widely used by other
architectures this feature can be enabled outside of x86 world.

This patch set promotes memtest to live under generic mm umbrella and enables
memtest feature for arm/arm64.

Patches are built on top of 4.0-rc1

Vladimir Murzin (4):
  mm: move memtest under /mm
  memtest: use phys_addr_t for physical addresses
  arm64: add support for memtest
  arm: add support for memtest
