[PATCH 0/3] [SCSI] mvsas: fix multiple shift issues

[Xi Wang <xi.wang@gmail.com>]

The main issue is that bit(n) is defined as:

	(u32)1 << n

Thus bit(n) with n >= 32 will produce 0 or 1, depending on the
architecture.  This is also undefined behavior in C.

The OR with sata_reg_set (u64) then doesn't work because bit()
does a 32-bit shift, which should have been a 64-bit shift:

	if (i >= 32) {
		mvi->sata_reg_set |= bit(i);
		...
	}

The other two patches fix similar oversized shift issues.
