+++ This bug was initially created as a clone of Bug #512638 +++ Description of problem: This patch removes the dependency of mmap_min_addr on CONFIG_SECURITY. It also sets a default mmap_min_addr of 4096. mmapping of addresses below 4096 will only be possible for processes with CAP_SYS_RAWIO. Upstream commit: http://git.kernel.org/linus/e0a94c2a63f2644826069044649669b5e7ca75d3
We don't have support for this at all, a proper backport of mmap_min_addr code can include this if it so chooses, but we don't really need a seperate BZ. We build with CONFIG_SECURITY, as long as the backport is done properly this patch will be meaningless to us.
Eric, I want to use this bz to implement mmap_min_addr separately from bz508843.
