Catalin Marinas	306219d59b	kselftest/arm64: mte: Skip the hugetlb tests if MTE not supported on such mappings ... While the kselftest was added at the same time with the kernel support for MTE on hugetlb mappings, the tests may be run on older kernels. Skip the tests if PROT_MTE is not supported on MAP_HUGETLB mappings.

Catalin Marinas	7ae95109c6	kselftest/arm64: mte: Use the correct naming for tag check modes in check_hugetlb_options.c ... The architecture doesn't define precise/imprecise MTE tag check modes, only synchronous and asynchronous. Use the correct naming and also ensure they match the MTE_{ASYNC,SYNC}_ERR type.
