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>
