This specific error seems to be pretty far spread. Guess you are saying that there is no plan to implement a workaround. Fair enough; I'll just remove the configuration from my list of tests. >> arm64:allmodconfig: >> >> drivers/firmware/qcom_scm-32.c:196:4: error: expected string literal before ‘__asmeq’ >> drivers/firmware/qcom_scm-32.c:221:2: error: implicit declaration of function ‘secure_flush_area’ >> drivers/firmware/qcom_scm-32.c:239:2: error: implicit declaration of function ‘outer_inv_range’ >> drivers/firmware/qcom_scm-32.c:331:4: error: expected string literal before ‘__asmeq’ >> drivers/firmware/qcom_scm-32.c:361:4: error: expected string literal before ‘__asmeq’ > > This file shouldn't be built on ARM64, and there's a fix in the pipeline > which obviously didn't make -rc1 for it. > Fixes are in the pipeline for most of the problems. Only exception is alpha; the patches necessary to fix the problems there only met silence. I'll probably wait for -rc4 or -rc5 and then send a pull request for everything that is left directly to Linus. Thanks, Guenter ^ permalink raw reply [flat|nested] 6+ messages in thread
