bugs. For 4.5 the bugs are fixed and we prepare a cleanup patch
for the next merge window.
- Three bug fixes for the dasd driver in regard to parallel access
volumes and the new max_dev_sectors block device queue limit
- The irq restore optimization needs a fixup for memcpy_real
- The diagnose trace code has a conflict with lockdep"
