This set of patches adds support for the Large Physical Extensions on
the ARM architecture (available with the Cortex-A15 processor). LPAE
comes with a 3-level page table format (compared to 2-level for the
classic one), allowing up to 40-bit physical address space.

The ARM LPAE documentation is available from (free registration needed):

http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406b_virtualization_extns/index.html

The full set of patches on top of linux-next (LPAE, support for an
emulated Versatile Express with Cortex-A15 tile and generic timers) is
available on this branch:

git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git arm-lpae-next

FYI, I'm going to drop the pgt patch because the warnings are still there

What warnings are you seeing? Could you please post them?

I tried with just your nopud patch on top of v2.6.39 and compiled for
vexpress. I don't get any warnings and I tried STRICT_MM_TYPECHECKS as
well.
