Query regarding randomization bits for a ASLR elf on PPC64

Hi Experts, I was recently looking at ways to extend the randomization range for a ASLR elf on a PPC64LE system. I basically have been using 28-bits of randomization on x86_64 for an ASLR elf using appropriate ARCH_MMAP_RND_BITS_MIN and ARCH_MMAP_RND_BITS_MAX values: http://lxr.free-electrons.co
