+Subject: [PATCH] Add PROT_NONE to the mprotect test.
+
+The mprotect unit test checks PROT_READ and PROT_READ | PROT_WRITE
+protections. We recently found that PROT_NONE wasn't properly
+supported in our huge page kernel code.
+
+This patch adds PROT_NONE tests to mprotect. The expected behaviour
+is that neither reads nor writes should succeed.
