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).


Catalin Marinas (4):
     ARM: Remove the domain switching on ARMv6k/v7 CPUs
     ARM: Assume new page cache pages have dirty D-cache
     ARM: Synchronise the I and D caches via set_pte_at() on SMP systems
     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.

Thanks.

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

It's a bit more intrusive and I'd like to push it to linux-next (but
still waiting for review on this list).
