These patch series adds below kselftests to test the user-space support for the ARMv8.5 Memory Tagging Extension present in arm64 tree [1]. This patch series is based on Linux v5.9-rc3.
- This test-case verifies that the memory allocated by kernel mmap interface
can support tagged memory access. It first checks the presence of tags at address[56:59] and then proceeds with read and write. The pass criteria for this test is that tag fault exception should not happen.

Applied to arm64 (for-next/late-arrivals), thanks!
