https://git.kernel.org/arm64/c/eb27c76ac9e1
[2/5] kselftest/arm64: add crc32 feature to hwcap test
https://git.kernel.org/arm64/c/09d2e95a04ad
[3/5] kselftest/arm64: add DEF_SIGHANDLER_FUNC() and DEF_INST_RAISE_SIG() helpers
https://git.kernel.org/arm64/c/71b634aba362
[4/5] kselftest/arm64: add test item that support to capturing the SIGBUS signal
https://git.kernel.org/arm64/c/fd49cf088867
[5/5] kselftest/arm64: add lse and lse2 features to hwcap test
https://git.kernel.org/arm64/c/82e7882b141c
