[PATCH v4 11/34] KVM: selftests: Convert debug-exceptions to printf style GUEST_ASSERT

From: Sean Christopherson
Date: Fri Jul 28 2023 - 20:38:30 EST


Convert ARM's debug exceptions test to use printf-based GUEST_ASSERT().
Opportunistically Use GUEST_ASSERT_EQ() in guest_code_ss() so that the
expected vs. actual values get printed out.
