mm: move memtest under mm
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.
It was reported that this patch set was useful for tracking down an issue
with some errant DMA on an arm64 platform.
This patch (of 6):
There is nothing platform dependent in the core memtest code, so other
platforms might benefit from this feature too.
