-          This is the portion of low virtual memory which should be protected
-          from userspace allocation.  Keeping a user from writing to low pages
-          can help reduce the impact of kernel NULL pointer bugs.

-          For most ia64, ppc64 and x86 users with lots of address space
-          a value of 65536 is reasonable and should cause no problems.
-          On arm and other archs it should not be higher than 32768.
-          Programs which use vm86 functionality would either need additional
-          permissions from either the LSM or the capabilities module or have
-          this protection disabled.

-          This value can be changed after boot using the
-          /proc/sys/vm/mmap_min_addr tunable.
