CVS commit: syssrc/sys/uvm



Module Name:    syssrc
Committed By:   drochner
Date:           Thu Jun 27 18:05:30 UTC 2002

Modified Files:
        syssrc/sys/uvm: uvm_pglist.c

Log Message:
Big cleanup and speed improvements to pglist_alloc code:
-pass vm_physseg* instead of physseg index, and PFN (int) instead
 of physical address (could be done even more)
-simplify detection of boundary crossing and behave more intelligently
 in this case
-take stuff out of the inner loops, or put into "#ifdef DEBUG"
 (because we move along physsegs we don't need to check that the
  pages are physically contigous)
-make the "simple" and "contigous" branches look more uniform; at
 least the outer loops might coalesce one day
