...a mem boundary at bootup, the page count populated isn't correct. This is due to mem populated to non-mem region and ignored. Pfn range is also wrongly aligned when mem boundary isn't page aligned. Also need consider the rare case when xen_do_chunk fail(populate). For a dom0 booted with dom_mem=3368952K(0xcd9ff000-4k) dmesg diff is: [ 0.000000] Freeing 9e-100 pfn range: 98 pages freed [ 0.000000] 1-1 mapping on 9e->100 [ 0.000000] 1-1 mapping on cd9ff->100000 [ 0.000000] Released 98 pages of unused memory [ 0.000000] Set 206435 page(s) to 1-1 mapping -[ 0.0000...

...page count populated isn't correct. This is due to mem populated to non-mem region and ignored. Pfn range is also wrongly aligned when mem boundary isn't page aligned. -v2: If xen_do_chunk fail(populate), abort this chunk and any others. Suggested by David, thanks.
