I am seeing a couple of objtool warnings in allmodconfig builds in current mainline. One of them is fixed by Borislav's patch [1], but I do not see a fix for the other one: vmlinux.o: warning: objtool: exc_nmi+0x2b3: call to __const_udelay() leaves .noinstr.text section Borislav's older fix [2] is in tree. I see this with gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04) and also with gcc version 8.5.0 20210514 (Red Hat 8.5.0-18) (GCC). Thoughts?
