This series looks fine, but why is it still incomplete? That is, it's
missing your drm commit plus the 4 I layered on top for moving to a
Kconfig-based approach and accounting for the bump to binutils 2.23.
Everything is now rebased here:
https://git.zx2c4.com/linux-dev/log/?h=jd/kconfig-assembler-support

Would you be up for resubmitting those all together so we can handle
this in one go?
