In order to do that xenbus_probe has been moved out of the xenbus initialization and called it later on at device_initcall. - a new HVMOP_pagetable_dying hypercall has been added to notify Xen that a pagetable is going to be destroyed: this improves performances significantly when running on shadow pagetables. A patch is currently need on the Xen side for this to work. Jeremy's comments have been addressed: - xen_guest_init has been renamed xen_hvm_guest_init; - init_hvm_time has been moved to arch/x86/xen/time.c; Konrad's comments have been addressed: - gnttab_max_nr_grant_frames has been renamed gnttab_max_grant_frames; - few inaccurate comments have been rewritten; - the preprocessor checks in platform-pci-unplug.c have been moved to platform_pci.h; - few other code style improvements, like using dev_err instead of printk and strncmp instead of strcmp.
