Nice implementation. I tested it and it fixes the problem on the affected
system.
Just a minor typo in a comment: "it's duty" should be "its duty".

I added some more instrumentation and discovered that the result of
xen_count_remap_pages() (0x85dea) is one less than the actual number
of pages remapped by xen_set_identity_and_remap() (0x85deb).
The two functions differ in their handling of a xen_e820_map entry
whose size is not a multiple of t

a recent stable xen 4.5. I'm capping the dom0 memory by setting
dom0_mem=18432M,max:18432M on the xen command line, and the kernel
config has CONFIG_XEN_BALLOON unset.
The crash seems dependent on the contents of the e820 table; ide
