This is just an FYI/acknowledgment that net/wireless/certs/*.x509 binary file(s) practically kills use of Linux kernel tarballs.
Of course, someone can always enable EXPERT and CFG80211_CERTIFICATION_ONUS and disable the REGDB kconfig symbols to get around this. Oh, and then chmod +x tools/objtool/sync-check.sh (unrelated problem). Then you are good to go. :) Background: I was getting build errors on net/wireless/shipped-certs.o and the build log didn't help me at all. It just said something like, Error: build failed on net/wireless/shipped-certs.o. Even building with V=1 didn't help. So I finally discovered the reason and worked around it. -- ~Randy PS: Yes, I know about git.
