# HG changeset patch # User awilliam@xxxxxxxxxxx # Node ID 6526a91d55553b712cb210cbefb363e71b380679 # Parent ecc8595f2c0b49684e40b4601f1a27f1df152528 [IA64] take start_info page from dom0 page not from xen heap. start_info page is used for xen to pass start up information to domain0 and the page is used only by dom0 so that it should belong to dom0.
