hi I try to understand the code of balloon ,and got confused about the following parts of code: static int decrease_reservation(unsigned long nr_pages) { .... if (!PageHighMem(page)) { v = phys_to_virt(pfn << PAGE_SHIFT); scrub_pages(v, 1); ret = HYPERVISOR_update_va_mapping( (unsigned long)v, __pte_ma(0), 0);

Hi Jeremy. Here are the 3 patches for ia64/xen support. The first one is just to move manage.c under drivers/xen. This is trivial. The second and third ones are for compilation fix on ia64. You may want to postpone those 2 patches to make your merge task easy as you said before. thanks, Diffstat arch/x86/xen/Makefile | 2 +- drivers/xen/Makefile | 2 +-
