Change patch format to remove Git version * Patches 0001-0122 only have the patch format modified Update to the head of the upstream staging branch plus redhat patches * Patches 0123-0134 & 1036-0142 are from the upstream staging branch * Patches 0143-1046 have been submitted upstream * Patch 0156 is a Red Hat only patch. Red Hat udev rules set ID_SERIAL from 60-persistent-storage.rules instead of 55-scsi-sg3_id.rules. Multipath's parse_vpd_pg83() function needs to match the ID_SERIAL value from udev. Rename files * Previous patches 0123-0132 are now patches 1035 & 0147-0155
