sys/vm vm_map.c
Log:
Correct an error in vm_map_sync(), nee vm_map_clean(), that has existed
since revision 1.1. Specifically, neither traversal of the vm map checks
whether the end of the vm map has been reached. Consequently, the first
traversal can wrap around and bogusly return an error.
This error has gone unnoticed for so long because no one had ever before
tried msync(2)ing a region above the stack.
