From: "Siluvery, Arun" <arun.siluvery@xxxxxxxxx> When a mapping is requested and if there is no space the mapping fails and the region is not physically backed. This results in signal 7(SIGBUS), code 2 (BUS_ADRERR) when it is actually accessed. This patch handles this error, continues to wait and retries to find space.
