Merge branch 'stable/for-jens-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen into for-linus
Konrad writes: Please pull in your 'for-linus' branch two little fixes for Xen block front: One fix is for handling the XEN_PAGE_SIZE != PAGE_SIZE (4KB vs 64KB on ARM for example) mishandling while the other is fixing the accounting for the configuration changes.
