The Fn pmap_object_init_pt function preloads the page table entries into the specified physical map Fa pmap , for the given Fa object at the virtual address Fa addr , for Fa size bytes, beginning at the page index Fa pindex within the object. The map bits Fa limit are heeded when creating the mapping.IMPLEMENTATION NOTES
This function is not strictly required by an architecture's pmap(9) implementation, but it does provide performance benefits if implemented.It is intended to eliminate the blast of soft faults on process startup, and immediately following a call to mmap(2).
