Pretty much the same content as v3 but I reordered the last three
patches to make sure that switching to lazy cache flushing on ARMv7 SMP
doesn't make the set_pte/cache flushing race more visible (issue handled
by the set_pte_at patch).

? ? ?ARM: Use lazy cache flushing on ARMv7 SMP systems

I've tried patches 2, 3, and 4 on a Cortex-A9 SMP system and it resolves the
MMC rootfs init crash without the need for the flush_kernel_dcache_page()
change.

P.S.: Patch 1 (at least the version on your proposed branch), doesn't seem to
apply cleanly on linux-next.
