This testcase checks the different unsupported/supported options for mmap if used with PROT_MTE memory protection flag. These checks are, * Either pstate.tco enable or prctl PR_MTE_TCF_NONE option should not cause any tag mismatch faults. * Different combinations of anonymous/file memory mmap, mprotect, sync/async error mode and private/shared mappings should work. * mprotect should not be able to clear the PROT_MTE page property.
