Hi all,

This is the second part of the boot/memory rework for Xen on Arm. This
part contains mostly clean-up & fixes found during the rework.

The first part of the rework is "xen/arm: TLB flush helpers rework" [1].

For convenience, I provided a branch with all the patches applied based
on next-4.13 (it is staging + patch queued for Arm):

git://xenbits.xen.org/people/julieng/xen-unstable.git branch mm/part2/v1

Cheers,
