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. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
