Lorenzo Stoakes 8b09bb5c42 selftests/perf_events: Add a mmap() correctness test ... commit 084d2ac403 upstream. Exercise various mmap(), munmap() and mremap() invocations, which might cause a perf buffer mapping to be split or truncated. To avoid hard coding the perf event and having dependencies on architectures and configuration options, scan through event types in sysfs and try to open them. On success, try to mmap() and if that succeeds try to mmap() the AUX buffer. In case that no AUX buffer supporting event is found, only test the base buffer mapping. If no mappable event is found or permissions are not sufficient, skip the tests. Reserve a PROT_NONE region for both rb and aux tests to allow testing the case where mremap unmaps beyond the end of a mapped VMA to prevent it from unmapping unrelated mappings.
