Can you split it into a series of smaller patches? 1/4: changes for arch/um/include/shared/irq_user.h and arch/um/os-Linux/signal.c 2/4: remove wrong <stdbool.h> or <stddef.h> inclusions (or maybe you need to replace them with <linux/types.h> to keep the affected headers self-contained) 3/4: add include/linux/stdarg.h, then <stdarg.h> with <linux/stdarg.h> 4/4: move -isystem $(shell $(CC) -print-file-name=include) to some sub-Makefiles from the top Makefile. (please note 4/4 will introduce a breakage in linux-next if somebody adds a new <stdarg.h> inclusion in this development cycle. I hope that will not happen, though) -- Best Regards Masahiro Yamada

First, userspace headers can be under incompatible license. Second, kernel doesn't require userspace to operate and should not require anything from userspace to be built other than compiler. We would use -ffreestanding too if not builtin function shenanigans.
