After several pings by Al (sorry about that!), I got around to review a
rebased version of this patchset at

  git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git asm-exports

The kbuild commits are good, but since we are close to the end of the
merge window, I will apply them to my kbuild branch after 4.8-rc1.

The rebased patchset is now in kbuild.git#kbuild. Before pushing, I
noticed one issue: For some reason,
drivers/firmware/efi/libstub/lib-ksyms.o is regenerated each time,
leading to relink of vmlinux. I'm looking into this.

OK, it's the

$(obj)/lib-%.o: $(srctree)/lib/%.c FORCE
        $(call if_changed_rule,cc_o_c)

rule in drivers/firmware/efi/libstub/Makefile file that conflicts with
the lib-ksyms.o rule. I need to find a better solution to this hack.
