Subject: [PATCH 0/2] xen/swiotlb: Add support for 64KB page granularity,

Hi all,

This small series add support for 64KB guests in swiotlb. It's based on
top of my 64KB page granularity support [1].

It has been tested on both 4KB and 64KB page granularity DOM0 by using an
LVM partition for the guest rootfs.

Regards,
