commit cb0ca08b326aa03f87fe94bb91872ce8d2ef1ed8 upstream. If gcc decides not to inline in_softirq_really(), objtool warns about a function call with UACCESS enabled: kernel/kcov.o: warning: objtool: __sanitizer_cov_trace_pc+0x1e: call to in_softirq_really() with UACCESS enabled kernel/kcov.o: warning: objtool: check_kcov_mode+0x11: call to in_softirq_really() with UACCESS enabled Mark this as __always_inline to avoid the problem.
