Looking at that branch: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/log/?h=x86/build I think we can send the whole thing even. Linus, shout if you'd prefer only the last three commits there: 950a37078aa0 x86/build: Use $(CONFIG_SHELL) f670269a42bf x86: Fix early boot crash on gcc-10, next try 73da86741e7f x86/build: Check whether the compiler is sane but the other three from Masahiro are simple cleanups: 675a59b7dec6 x86/boot/build: Add phony targets in arch/x86/boot/Makefile to PHONY 30ce434e44d7 x86/boot/build: Make 'make bzlilo' not depend on vmlinux or $(obj)/bzImage e3c7c1052271 x86/boot/build: Add cpustr.h to targets and remove clean-files which should be ok to take now too AFAICT.
