[Patch V6 13/16] xen: add explicit memblock_reserve() calls for special pages

2015-07-16 Thread Juergen Gross
Some special pages containing interfaces to xen are being reserved implicitly only today. The memblock_reserve() call to reserve them is meant to reserve the p2m list supplied by xen. It is just reserving not only the p2m list itself, but some more pages up to the start of the xen built page
