VM_SET_PAGE_SIZE(9)					   BSD Kernel Developer's Manual				       VM_SET_PAGE_SIZE(9)

NAME
     vm_set_page_size -- initialize the system page size

SYNOPSIS
     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/vm_page.h>

     void
     vm_set_page_size(void);

DESCRIPTION
     The vm_set_page_size() function initializes the system page size.	If vm_cnt.v_page_size (see <sys/vmmeter.h>) equals 0, PAGE_SIZE is used;
     otherwise, the value stored in vm_cnt.v_page_size is used.  If vm_cnt.v_page_size is not a power of two, the system will panic.

     vm_set_page_size() must be called prior to any page size dependent functions.
