SELinux checks whether VM_EXEC is set in the VM_DATA_DEFAULT_FLAGS during initialization and saves the result in default_noexec for use in its mmap and mprotect hook function implementations to decide whether to apply EXECMEM, EXECHEAP, EXECSTACK, and EXECMOD checks. Mark default_noexec as ro_after_init to prevent later clearing it and thereby disabling these checks. It is only set legitimately from init code.
