It's easy enough to figure out whose patch this was.
$ git log -p next-20220511 arch/sh/include/asm/hugetlb.h

Thanks for reporting. I'm sorry for my stupid mistakes. I've sent out a V4 to fix building issues[1], and Stephen will update today's (next-20220512) linux-next. Please test today's linux-next. Sorry for troubles again.
