cluster page faults into a process's address
() function provides a
means of clustering pagefaults into a process's address space. It operates
upon the physical map pmap
argument specifies the entry to be
prefaulted; the addra
argument specifies the
beginning of the mapping in the process's virtual address space.
It is typically called by
the first page fault. It benefits the
system call by eliminating repetitive calls to
(), which would otherwise be made
to bring the process's executable pages into physical memory.
This is a machine-independent function which calls the machine-dependent
helper function to determine if a page may be prefaulted into physical memory.
