CVS commit: src/sys/uvm

[Andrew Brown <atatat%netbsd.org@localhost>]

Module Name:    src
Committed By:   atatat

Modified Files:
        src/sys/uvm: uvm_glue.c

Log Message:
Rework the way in which the map is traversed when dumping core.  Now
we read-lock the map and call uvm_map_lookup_entry() instead of simply
walking from the header to the next and to the next, etc.

Dumping from sparsely populated amaps could cause faults that would
result in amaps being split, which (in turn) resulted in the core
dumping routines dumping some regions of memory twice.  This makes the
core file too large, the headers not match, gdb not work properly,
and so on.

Addresses PR 19260.
