This adds ~27k of these warnings to W=1 gcc builds:

include/linux/skbuff.h:851:1: warning: directive in macro's argument list

compiler version[1] and base commit[2] were used here?  

gcc version 11.2.1 20210728 (Red Hat 11.2.1-1) (GCC) 

HEAD was at: 3b1abcf12894 Merge tag 'regmap-no-bus-update-bits' of git://...
