selftests/powerpc/pmu: Refactor the platform check and add macros to find array size/PVR
The platform check for selftest support "check_pvr_for_sampling_tests" is specific to sampling tests which includes PVR check, presence of PMU and extended regs support. Extended regs support is needed for sampling tests which tests whether PMU registers are programmed correctly. There could be other sampling tests which may not need extended regs, example, bhrb filter tests which only needs validity check via event open.
Hence refactor the platform check to have a common function "platform_check_for_tests" that checks only for PVR check and presence of PMU. The existing function "check_pvr_for_sampling_tests" will invoke the common function and also will include checks for extended regs specific for sampling. The common function can also be used by tests other than sampling like event code tests.
Add macro to find array size ("ARRAY_SIZE") to sampling tests "misc.h" file. This can be used in next tests to find event array size. Also update "include/reg.h" to add macros to find minor and major version from PVR which will be used in testcases.

selftests/powerpc: Add a signal fuzzer selftest
This is a new selftest that raises SIGUSR1 signals and handles it in a set of different ways, trying to create different scenario for testing purpose.
This test works raising a signal and calling sigreturn interleaved with TM operations, as starting, suspending and terminating a transaction. The test depends on random numbers, and, based on them, it sets different TM states.
Other than that, the test fills out the user context struct that is passed to the sigreturn system call with random data, in order to make sure that the signal handler syscall can handle different and invalid states properly.
This selftest has command line parameters to control what kind of tests the user wants to run, as for example, if a transaction should be started prior to signal being raised, or, after the signal being raised and before the sigreturn. If no parameter is given, the default is enabling all options.
This test does not check if the user context is being read and set properly by the kernel. Its purpose, at this time, is basically guaranteeing that the kernel does not crash on invalid scenarios.

selftests/powerpc: New TM signal self test
A new self test that forces MSR[TS] to be set without calling any TM instruction. This test also tries to cause a page fault at a signal handler, exactly between MSR[TS] set and tm_recheckpoint(), forcing thread->texasr to be rewritten with TEXASR[FS] = 0, which will cause a BUG when tm_recheckpoint() is called.
This test is not deterministic, since it is hard to guarantee that the page access will cause a page fault. In order to force more page faults at signal context, the signal handler and the ucontext are being mapped into a MADV_DONTNEED memory chunks.
Tests have shown that the bug could be exposed with few interactions in a buggy kernel. This test is configured to loop 5000x, having a good chance to hit the kernel issue in just one run. This self test takes less than two seconds to run.
This test uses set/getcontext because the kernel will recheckpoint zeroed structures, causing the test to segfault, which is undesired because the test needs to rerun, so, there is a signal handler for SIGSEGV which will restart the test.

selftests/powerpc: Add a signal fuzzer selftest This is a new selftest that raises SIGUSR1 signals and handles it in a set of different ways, trying to create different scenario for testing purpose. This test works raising a signal and calling sigreturn interleaved with TM operations, as starting, suspending and terminating a transaction. The test depends on random numbers, and, based on them, it sets different TM states. Other than that, the test fills out the user context struct that is passed to the sigreturn system call with random data, in order to make sure that the signal handler syscall can handle different and invalid states properly. This selftest has command line parameters to control what kind of tests the user wants to run, as for example, if a transaction should be started prior to signal being raised, or, after the signal being raised and before the sigreturn. If no parameter is given, the default is enabling all options. This test does not check if the user context is being read and set properly by the kernel. Its purpose, at this time, is basically guaranteeing that the kernel does not crash on invalid scenarios.

selftests/powerpc: New TM signal self test A new self test that forces MSR[TS] to be set without calling any TM instruction. This test also tries to cause a page fault at a signal handler, exactly between MSR[TS] set and tm_recheckpoint(), forcing thread->texasr to be rewritten with TEXASR[FS] = 0, which will cause a BUG when tm_recheckpoint() is called. This test is not deterministic, since it is hard to guarantee that the page access will cause a page fault. In order to force more page faults at signal context, the signal handler and the ucontext are being mapped into a MADV_DONTNEED memory chunks. Tests have shown that the bug could be exposed with few interactions in a buggy kernel. This test is configured to loop 5000x, having a good chance to hit the kernel issue in just one run. This self test takes less than two seconds to run. This test uses set/getcontext because the kernel will recheckpoint zeroed structures, causing the test to segfault, which is undesired because the test needs to rerun, so, there is a signal handler for SIGSEGV which will restart the test. v2: Uses the MADV_DONTNEED memory advice v3: Fix memcpy and 32-bits compilation v4: Does not define unused macros Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
