Anton Blanchard 002b0ec73d powerpc: Increase stack gap on 64bit binaries ... On 64bit there is a possibility our stack and mmap randomisation will put the two close enough such that we can't expand our stack to match the ulimit specified. To avoid this, start the upper mmap address at 1GB + 128MB below the top of our address space, so in the worst case we end up with the same ~128MB hole as in 32bit. This works because we randomise the stack over a 1GB range.
