["Andrew Doran" <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Mon May 25 21:15:10 UTC 2020

Modified Files:
        src/sys/arch/hppa/hppa: pmap.c
        src/sys/miscfs/genfs: genfs_io.c
        src/sys/nfs: nfs_subs.c
        src/sys/uvm: uvm_aobj.c uvm_object.c uvm_page_array.c uvm_page_array.h
            uvm_vnode.c

Log Message:
- Alter the convention for uvm_page_array slightly, so the basic search
  parameters can't change part way through a search: move the "uobj" and
  "flags" arguments over to uvm_page_array_init() and store those with the
  array.

- With that, detect when it's not possible to find any more pages in the
  tree with the given search parameters, and avoid repeated tree lookups if
  the caller loops over uvm_page_array_fill_and_peek().
