    SYNOPSIS

       #include <sys/param.h>
       #include <vm/vm.h>
       #include <vm/pmap.h>
    void pmap_remove (pmap_t pmap vm_offset_t sva vm_offset_t eva);
    void pmap_remove_all (vm_page_t m);
    void pmap_remove_pages (pmap_t pmap);
     

    DESCRIPTION

    The pmap_remove ();
    function removes the range of addresses between Fa sva and Fa eva from the physical map Fa pmap . If Fa eva is less than Fa sva , then the result is undefined. It is assumed that both Fa sva and Fa eva are page-aligned addresses.

    The pmap_remove_all ();
    removes the physical page Fa m from all physical maps in which it resides, and reflects back the modify bits to the appropriate pager.

    The pmap_remove_pages ();
    function removes all user pages from the physical map Fa pmap . This function is called when a process exits to run down its address space more quickly than would be the case for calling pmap_remove (.);
