to the machine-independent parts of the VM. At the same time, this introduces vm object locking for the non-i386 platforms. Two details: 1. KSTACK_GUARD has been removed in favor of KSTACK_GUARD_PAGES. The different machine-dependent implementations used various combinations of KSTACK_GUARD and KSTACK_GUARD_PAGES. To disable guard page, set KSTACK_GUARD_PAGES to 0. 2. Remove the (unnecessary) clearing of PG_ZERO in vm_thread_new. In 5.x, (but not 4.x,) PG_ZERO can only be set if VM_ALLOC_ZERO is passed to vm_page_alloc() or vm_page_grab().
