2022-09-07	kselftest/arm64: Allow larger buffers in get_signal_context()	Mark Brown	1	-1/+1
	In order to allow testing of signal contexts that overflow the base signal frame allow callers to pass the buffer size for the user context into get_signal_context(). No functional change.

2019-11-08	kselftest: arm64: fake_sigreturn_bad_magic	Cristian Marussi	1	-0/+52
	Add a simple fake_sigreturn testcase which builds a ucontext_t with a bad magic header and place it onto the stack. Expects a SIGSEGV on test PASS. Introduce a common utility assembly trampoline function to invoke a sigreturn while placing the provided sigframe at wanted alignment and also an helper to make space when needed inside the sigframe reserved area.
