Backport of RHEL-5/linux-2.6-xen-pvfb-probe-suspend-fixes.patch and
RHEL-5/linux-2.6-xen-pvfb-probe-suspend-fixes-fix.patch rolled together.
I redid the patch myself; I didn't use clear_page but, anyway, the only major difference between my patch and the one in comment #2 is that this:
info->page = (void *)__get_free_page(GFP_KERNEL);
had a dereference-before-checking-for-NULL bug. Thanks!
