[PATCH v5 0/7] xen/arm: move to mach-virt and support SMP

[Stefano Stabellini]

Arnd, Olof,
during the last few merge windows Konrad has always sent the Xen ARM
patches to Linus via his tree, but this time (3.10 merge window), after
consulting with Konrad I am thinking of sending to Linus the pull
request myself.

Arnd, are you OK with this patch series?

It's all very Xen specific and it is already in linux-next.
The only non-Xen files that are touched are arch/arm/Kconfig, to select
ARM_PSCI on XEN, and arch/arm/boot/dts/Makefile, to build the xenvm DTB
if CONFIG_ARCH_VIRT.

Cheers,

Stefano
