Daniel Cashman 8f0d3aa9de arm64: mm: support ARCH_MMAP_RND_BITS 
arm64: arch_mmap_rnd() uses STACK_RND_MASK to generate the random offset
for the mmap base address.  This value represents a compromise between
increased ASLR effectiveness and avoiding address-space fragmentation.
Replace it with a Kconfig option, which is sensibly bounded, so that
platform developers may choose where to place this compromise.  Keep
default values as new minimums.
