ptrace.c	kselftest/arm64: Add a smoke test for ptracing hardware break/watch points There was a report that the hardware breakpoints and watch points weren't reporting the debug architecture version as expected, they were reporting a version of 0 which is not defined in the architecture. This happens when running in a KVM guest if the host has a debug architecture version not supported by KVM, it in turn confuses GDB which rejects any debug architecture version it does not know about. Add a test that covers that situation and while we're at it reports the debug architecture version and number of slots available to aid with figuring out problems that may arise.

syscall-abi-asm.S	kselftest/arm64: abi: fix SVCR detection [ Upstream commit ce03573a1917532da06057da9f8e74a2ee9e2ac9 ] When using svcr_in to check ZA and Streaming Mode, we should make sure that the value in x2 is correct, otherwise it may trigger an Illegal instruction if FEAT_SVE and !FEAT_SME.

syscall-abi.c	kselftest/arm64: Size sycall-abi buffers for the actual maximum VL Our ABI opts to provide future proofing by defining a much larger SVE_VQ_MAX than the architecture actually supports. Since we use this define to control the size of our vector data buffers this results in a lot of overhead when we initialise which can be a very noticable problem in emulation, we fill buffers that are orders of magnitude larger than we will ever actually use even with virtual platforms that provide the full range of architecturally supported vector lengths. Define and use the actual architecture maximum to mitigate this.

syscall-abi.h	kselftest/arm64: Add SME support to syscall ABI test For every possible combination of SVE and SME vector length verify that for each possible value of SVCR after a syscall we leave streaming mode and ZA is preserved. 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. We log if the system supports FA64 and only try to set FFR in streaming mode if it does.

tpidr2.c	kselftest/arm64: Add tests for TPIDR2 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.
