![]() M profile cores can never trap on WFI or WFE instructions. Check for M profile in check_wfx_trap() to ensure this. The existing code will do the right thing for v7M cores because the hcr_el2 and scr_el3 registers will be all-zeroes and so we won't attempt to trap, but when we start setting ARM_FEATURE_V8 for v8M cores the v8A handling of SCTLR.nTWE and .nTWI will not give the right results.
