63ed71019c pata_pdc202xx_old: fix data corruption and other problems
Fix wrong "port" calculations in pdc202xx_{configure_piomode,set_dmamode}()
They were broken for all configurations except one (master device on primary
channel, no other devices) and as a result device settings + PIO/DMA timings
were being programmed into the wrong PCI registers.  This could result in
a large variety of problems including data corruption, hangs etc. (depending
on devices used and your luck :-).

  ap->port_no   ap->devno   used PCI registers   correct PCI registers
            0           0            0x60-0x62               0x60-0x62
            0           1            0x62-0x64               0x64-0x66
            1           0            0x64-0x66               0x68-0x6a
            1           1            0x66-0x68               0x6c-0x6e

Also forward port recent fixes from drivers/ide pdc202xx_old driver:

* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)

* fix bitmasks for clearing bits of register B:

  - when programming DMA mode bit 0x10 of register B was cleared which
    resulted in overclocked PIO timing setting (iff PIO0 was used)

  - when programming PIO mode bits 0x18 weren't cleared so suboptimal
    timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
    and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)

and finally bump driver version.

8b966dddc2 pata_legacy: fix io/irq mismatch
pata_legacy fails to detect the disk on my old ISA/VLB 486:
it starts to probe io=0x1f0 ctr=0x3f6 irq=15, complains
loudly about IDENTIFYs timing out, and finally fails.
(Sorry I couldn't capture the kernel's boot messages.)

It turns out that the driver's mapping from io to irq in
legacy_irq[] is wrong: index 0 for io=0x1f0 has irq=15 but
should have irq=14, and index 1 for io=0x170 has irq=14 but
should have irq=15. This is confirmed by a comparison with
include/asm-i386/ide.h:ide_default_irq().

This patch swaps the first two elements in legacy_irq[],
which makes pata_legacy work on my 486.

f31f0cc2f0 [libata] change master/slave IDENTIFY order
2.6.21-rc has horrible problems with libata and PATA cable types (and
thus speeds). This occurs because Tejun fixed a pile of other bugs and
we now do cable detect enforcement for drive side detection properly.

Unfortunately we don't do the process around cable detection right. Tejun
identified the problem and pointed to the right Annex in the spec, this patch
implements the needed changes.

The basic requirement is that we have to identify the slave before the
master.

The patch switches the identify order so that we can do the drive side
detection correctly.

and signed-off-by Alan Cox]

032af1ce16 libata-core: Fix simplex handling
The initial simplex handling code is fooled if you suspend and resume.
This also causes problems with some single channel controllers which
claim to be simplex.

The fix is fairly simple, instead of keeping a flag to remember if we
gave away the simplex channel we remember the actual owner. As the owner
is always part of the host_set we don't even need a refcount.

Knowing the owner also means we can reassign simplex DMA channels in
future hotplug code etc if we need to

098cdff3d4 sata_promise: simplify port setup
Each place in pdc_ata_init_one() that initialises a SATA
port first calls pdc_ata_setup_port(), and then manually
assigns the port's ->scr_addr. Simplify the code by extending
pdc_ata_setup_port() to also handle scr_addr initialisation;
for PATA ports we pass NULL as scr_addr.

The initialisation of the PATA-only 20619 redundantly set
up scr_addr for the ports. Remove this.

Tested on 20619, 20575, and 20775 chips.

ea34e45a46 sata_vsc: refactor vsc_sata_interrupt and hook up error handling
Separate sata_vsc interrupt handling into a normal (per-port) path and an
error path with the addition of vsc_port_intr and vsc_error_intr
respectively.  The error path handles interrupt based
hotplug events which requires the definition of vsc_freeze and vsc_thaw.

Note: vsc_port_intr has a workaround for unexpected interrupts that occur
during polled commands.  This fixes a regression between 2.6.19 and 2.6.20.

Changes in take2:
* removed definition of invalid fis bit
* let standard ata-error-handling handle the serror register
* clear all unhandled interrupts
* revert changes to vsc_intr_mask_update (vsc_thaw enables all interrupts)
* use unlikely() for the pci-abort and not-our-interrupt cases in vsc_sata_interrupt

Changes in take3:
* Unify the "add" + "hook-up" patches into this single patch

since the ADMA BMDMA status registers are PIO while the other registers

The only thing we need to override as far as ADMA and BMDMA is the

SDB FIS containing spurious NCQ completions is a clear protocol

after it.  EH will turn off NCQ after this happens several times.
Eventually drives which show this behavior should be blacklisted for

44877b4e22 libata: s/ap->id/ap->print_id/g
ata_port has two different id fields - id and port_no.  id is
system-wide 1-based unique id for the port while port_no is 0-based
host-wide port number.  The former is primarily used to identify the
ATA port to the user in printk messages while the latter is used in
various places in libata core and LLDs to index the port inside the
host.

The two fields feel quite similar and sometimes ap->id is used in
place of ap->port_no, which is very difficult to spot.  This patch
renames ap->id to ap->print_id to reduce the possibility of such bugs.

Some printk messages are adjusted such that id string (ata%u[.%u])
isn't printed twice and/or to use ata_*_printk() instead of hardcoded
id format.
