lsm: preserve /proc/sys/vm/mmap_min_addr when !CONFIG_SECURITY
While reworking the LSM initialization code the
/proc/sys/vm/mmap_min_addr handler was inadvertently caught up in the
change and the procfs entry wasn't setup when CONFIG_SECURITY was not
selected at kernel build time. This patch restores the previous behavior
and ensures that the procfs entry is setup regardless of the
CONFIG_SECURITY state.
Future work will improve upon this, likely by moving the procfs handler
into the mm subsystem, but this patch should resolve the immediate
regression.
Fixes: 4ab5efcc2829 ("lsm: consolidate all of the LSM framework initcalls")
