Subject: linux-next: build failure after merge of the vfs tree

Hi all,

After merging the vfs tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

In file included from arch/x86/include/asm/elf.h:8,
                 from include/linux/elf.h:6,
                 from include/linux/elfcore-compat.h:5,
                 from fs/compat_binfmt_elf.c:17:

Caused by commit

  5a9b7f382248 ("binfmt_elf: partially sanitize PRSTATUS_SIZE and SET_PR_FPVALID")

or maybe commit

  9866fcab1c65 ("[elfcore-compat][amd64] clean PRSTATUS_SIZE/SET_PR_FPVALID up properly")

I have used the vfs tree from next-20210104 for today.
