Maciej W. Rozycki 7d33004d24 pata_legacy: Add `probe_mask' parameter like with ide-generic
Carry the `probe_mask' parameter over from ide-generic to pata_legacy so
that there is a way to prevent random poking at ISA port I/O locations
in attempt to discover adapter option cards with libata like with the
old IDE driver.  By default all enabled locations are tried, however it
may interfere with a different kind of hardware responding there.

For example with a plain (E)ISA system the driver tries all the six
possible locations:

scsi host0: pata_legacy
ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14
ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100
ata1.00: 19541088 sectors, multi 16: LBA
ata1.00: configured for PIO
scsi 0:0:0:0: Direct-Access     ATA      ST310211A        3.54 PQ: 0 ANSI: 5
scsi 0:0:0:0: Attached scsi generic sg0 type 0
sd 0:0:0:0: [sda] 19541088 512-byte logical blocks: (10.0 GB/9.32 GiB)
sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00
sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
 sda: sda1 sda2 sda3
sd 0:0:0:0: [sda] Attached SCSI disk
scsi host1: pata_legacy
ata2: PATA max PIO4 cmd 0x170 ctl 0x376 irq 15
scsi host1: pata_legacy
ata3: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11
scsi host1: pata_legacy
ata4: PATA max PIO4 cmd 0x168 ctl 0x36e irq 10
scsi host1: pata_legacy
ata5: PATA max PIO4 cmd 0x1e0 ctl 0x3e6 irq 8
scsi host1: pata_legacy
ata6: PATA max PIO4 cmd 0x160 ctl 0x366 irq 12

however giving the kernel "pata_legacy.probe_mask=21" makes it try every
other location only:

scsi host0: pata_legacy
ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14
ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100
ata1.00: 19541088 sectors, multi 16: LBA
ata1.00: configured for PIO
