General fix

This prerequisite PTF allows V9R2 Service Pack 2 (M952) and later to be restored over a V9R2M951 and V9R2M950 image. If this PTF is not installed, the symptom on restore results in the following sequence:
The HMC restore will fail and results in the HMC crashing and halting at the following message:

"/sbin/reboot:symbol lookup error: /sbin/reboot: undefined symbol: bus_wait_for_units_new, version SD_SHARED"
