pci_interrupt_cause"
The direct cause is IRQ_SPI is already defined as a macro in unicore32
architecture (also, blackfin and mips architectures define it). The
related error (unicore32 with allmodconfig)
CC [M] drivers/scsi/mvsas/mv_94xx.o
In file included from drivers/scsi/mvsas/mv_94xx.c:27:
drivers/scsi/mvsas/mv_94xx.h:176: error: expected identifier before numeric constant
And IRQ_SAS_A and IRQ_SAS_B are used as 'u32' (although "enum
pci_interrupt_cause" is not used directly, now).
All together, need add 'MVS_' for "enum pci_interrupt_cause".

The macro bit(n) is defined as ((u32)1 << n), and thus it doesn't work
with n >= 32, such as in mvs_94xx_assign_reg_set():
if (i >= 32) {
mvi->sata_reg_set |= bit(i);
...
}
The shift ((u32)1 << n) with n >= 32 also leads to undefined behavior.
The result varies depending on the architecture.
This patch changes bit(n) to do a 64-bit shift. It also simplifies
mv_ffc64() using __ffs64(), since invoking ffz() with ~0 is undefined.

1. Add support for Task collector mode.
2. Fixed relative collector mode bug:
- I/O failed when disks is on two ports
- system hang when hotplug disk
- system hang when unplug disk during run IO
3. Unlock ap->lock within .lldd_execute_task for direct mode to
improve performance

This version contains following main changes
- Switch to new layout to support more types of ASIC.
- SSP TMF supported and related Error Handing enhanced.
- Support flash feature with delay 2*HZ when PHY changed.
- Support Marvell 94xx series ASIC for 6G SAS/SATA, which has 2
88SE64xx chips but any different register description.
- Support SPI flash for HBA-related configuration info.
- Other patch enhanced from kernel side such as increasing PHY type
[jejb: fold back in DMA_BIT_MASK changes]
