2022-04-28io_uring: use the text representation of ops in traceDylan Yudaken
It is annoying to translate opcodes to textwhen tracing io_uring. Use the io_uring_get_opcode function instead to use the text representation. A downside here might have been that if the opcode is invalid it will not be obvious, however the opcode is already overridden in these cases to 0 (NOP) in io_init_req(). Therefore this is a non issue.

2022-04-28selftests/arm64: Fix O= builds for the floating point testsMark Brown
Currently the arm64 floating point tests don't support out of tree builds due to two quirks of the kselftest build system. One is that when building a program from multiple files we shouldn't separately compile the main program to an object file as that will result in the pattern rule not matching when adjusted for the output directory. The other is that we also need to include $(OUTPUT) in the names of the binaries when specifying the dependencies in order to ensure that they get picked up with O=. Rewrite the dependencies for the executables to fix these issues. The kselftest build system will ensure OUTPUT is always defined.

We don't need to take account of any streaming/non streaming SVE vector length changes in the assembler code since the store instructions will handle the vector length for us.

2022-04-28kselftest/arm64: Add tests for TPIDR2Mark Brown
The Scalable Matrix Extension adds a new system register TPIDR2 intended to be used by libc for its own thread specific use, add some kselftests which exercise the ABI for it. Since this test should with some adjustment work for TPIDR and any other similar registers added in future add tests for it in a separate directory rather than placing it with the other floating point tests, nothing existing looked suitable so I created a new test directory called "abi". Since this feature is intended to be used by libc the test is built as freestanding code using nolibc so we don't end up with the test program and libc both trying to manage the register simultaneously and distrupting each other. As a result of being written using nolibc rather than using hwcaps to identify if SME is available in the system we check for the default SME vector length configuration in proc, adding hwcap support to nolibc seems like disproportionate effort and didn't feel entirely idiomatic for what nolibc is trying to do.

The current tests use the prctls for various things but there's no coverage of the edges of the interface so add some basics. This isn't hugely useful as it is (it originally had some coverage for the combinations with asymmetric mode but we removed the prctl() for that) but it might be a helpful starting point for future work, for example covering error handling.

2022-04-28kselftest/arm64: Handle more kselftest result codes in MTE helpersMark Brown
The MTE selftests have a helper evaluate_test() which translates a return code into a call to ksft_test_result_*(). Currently this only handles pass and fail, silently ignoring any other code. Update the helper to support skipped tests and log any unknown return codes as an error so we get at least some diagnostic if anything goes wrong.

2022-04-28kselftest/arm64: Validate setting via FPSIMD and read via SVE regsetsMark Brown
Currently we validate that we can set the floating point state via the SVE regset and read the data via the FPSIMD regset but we do not valiate that the opposite case works as expected. Add a test that covers this case, noting that when reading via SVE regset the kernel has the option of returning either SVE or FPSIMD data so we need to accept both formats.

2022-04-28kselftest/arm64: Remove assumption that tasks start FPSIMD onlyMark Brown
Currently the sve-ptrace test for setting and reading FPSIMD data assumes that the child will start off in FPSIMD only mode and that it can use this to read some FPSIMD mode SVE ptrace data, skipping the test if it can't. This isn't an assumption guaranteed by the ABI and also limits how we can use this testcase within the program. Instead skip the initial read and just generate a FPSIMD format buffer for the write part of the test, making the coverage more robust in the face of future kernel and test program changes.

2022-04-28net: enetc: allow tc-etf offload even with NETIF_F_CSUM_MASKVladimir Oltean
The Time-Specified Departure feature is indeed mutually exclusive with TX IP checksumming in ENETC, but TX checksumming in itself is broken and was removed from this driver in commit 82728b91f124 ("enetc: Remove Tx checksumming offload code"). The blamed commit declared NETIF_F_HW_CSUM in dev->features to comply with software TSO's expectations, and still did the checksumming in software by calling skb_checksum_help(). So there isn't any restriction for the Time-Specified Departure feature. However, enetc_setup_tc_txtime() doesn't understand that, and blindly looks for NETIF_F_CSUM_MASK. Instead of checking for things which can literally never happen in the current code base, just remove the check and let the driver offload tc-etf qdiscs.
