Add 0074-RHBZ-1056976-dm-mpath-rules.patch
* Add rules to keep from doing work in udev if there are no
active paths, or if the event was for a multipath device
reloading its table due to a path change.
Add 0075-RHBZ-1056976-reload-flag.patch
* multipath code to identify reloads that the new rules can
ignore
Add 0076-RHBZ-1056686-add-hw_str_match.patch
* add a new default config paramter, "hw_str_match", to make user
device configs only overwrite builtin device configs if the
identifier strings match exactly, like the default in RHEL6.
