2019-11-08kselftest: arm64: add helper get_current_contextCristian Marussi1-1/+5
Introduce a new common utility function get_current_context() which can be used to grab a ucontext without the help of libc, and also to detect if such ucontext has been successfully used by placing it on the stack as a fake sigframe.

2019-11-08kselftest: arm64: extend test_init functionalitiesCristian Marussi1-2/+5
Extend signal testing framework to allow the definition of a custom per test initialization function to be run at the end of the common test_init after test setup phase has completed and before test-run routine. This custom per-test initialization function also enables the test writer to decide on its own when forcibly skip the test itself using standard KSFT mechanism.

2019-11-08kselftest: arm64: mangle_pstate_invalid_compat_toggle and common utilsCristian Marussi1-0/+93
Add some arm64/signal specific boilerplate and utility code to help further testcases' development. Introduce also one simple testcase mangle_pstate_invalid_compat_toggle and some related helpers: it is a simple mangle testcase which messes with the ucontext_t from within the signal handler, trying to toggle PSTATE state bits to switch the system between 32bit/64bit execution state. Expects SIGSEGV on test PASS. Reviewed-by: Dave Martin <Dave.Martin@arm.com> Signed-off-by: Cristian Marussi <cristian.marussi@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
