I was holding off on those until I could gauge upstream reception. If
desired, I could put those together and add them as [PATCH 3/4] and
[PATCH 4/4].

arm: arch_mmap_rnd() uses a hard-code value of 8 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,
