a0db8a7516 scsi: myrs: Fix the processor absent message in processor_show()
If both processors are absent then it's supposed to print that, but
instead we print that just the second processor is absent.

d592dd6400 scsi: myrs: fix build failure on 32 bit

warning about _uldivmod being undefined in certain configurations

7726618639 scsi: myrs: Add Mylex RAID controller (SCSI interface)
This patch adds support for the Mylex DAC960 RAID controller,
supporting the newer, SCSI-based interface.  The driver is a
re-implementation of the original DAC960 driver.
