e04b3b9d03 ata_piix: kill incorrect invalid map value warning
The last two slots of MAP 00b of ich6m was incorrectly marked as
reserved.  This is left over from converting the entry to allow 00b.
This causes no real problem.  It only makes the driver print annoying
warning message.  Fix it.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

75683fe715 libata: clean up horkage handling
Horkage handling had the following problems.

* dev->horkage was positioned after ATA_DEVICE_CLEAR_OFFSET, so it was
  cleared before the device is configured.  This broke
  HORKAGE_DIAGNOSTIC.

* Some used dev->horkage while others called ata_device_blacklisted()
  directly.  This was at best confusing.

This patch moves dev->horkage right after dev->flags and set the field
according to the blacklist during device configuration.  All users
test against dev->horkage.  ata_device_blacklisted() now has only one
user, make it static.  While at it, rename it to ata_dev_blacklisted()
for consistency.

a77720ad0a sata_promise: SATA hotplug support, take 2
This patch enables hotplugging of SATA devices in the
sata_promise driver. It's been tested successfully on
both first- and second-generation Promise SATA chips:
SATA150 TX2plus, SATAII150 TX2plus, SATAII150 TX4,
SATA300 TX2plus, and SATA300 TX4.

The only quirk I've seen is that hotplugging (insertion)
on the first-generation SATA150 TX2plus requires a lengthier
EH sequence than on the second-generation chips.
On the second-generation chips a simple soft reset seems
to suffice, but on the first-generation chip there's a
"port is slow to respond" after the initial soft reset,
after which libata issues a hard reset, and then the
device is recognised.

The hotplug checks are high up in the interrupt handling
path, not deep down in error_intr as in ahci/sata_sil24.
That's because the chip doesn't signal hotplug status changes
in the per-port status register: instead a global register
contains hotplug control and status flags for all ports.
I considered following the ahci/sata_sil24 structure, but
that would have required non-trivial changes to the interrupt
handling path, so I chose to keep the hotplug changes simple
and unobtrusive.

This patch depends on the "sata_promise: cleanups" patch.

Changes since the previous version (posted June 19):
- Correct pdc_interrupt() to increment 'handled' also in
  the hotplug case. This prevents IRQ_NONE from being
  returned when an interrupt only has hotplug events to
  handle, which could confuse the kernel's IRQ machinery.
- Added testing on the SATAII150 TX4.

Add support for the SATA portion of Marvell's AHCI-compatible chips.
The PATA port capability, also available via AHCI, is disabled until

NCQ and PCI MSI are disabled by default.  Marvell says "we use NCQ" in
their drivers but "we do not use PCI MSI."  Theoretically that implies
we need to fix ahci.c to work with Marvell NCQ, but one wonders why
Marvell NCQ is any different from other AHCI chips.

825cd6dd79 sata_sil24: sil24_interrupt() micro-optimisation
sil24_interrupt() loads host->ports[i] into a local variable,
validates it, and then loads the value again in the call to
sil24_host_intr(). This patch replaces the second load by a
reference to the local variable.

This is safe since no side-effects have occurred since the
initial load. It also improves readability since it makes
it clear that the parameter to sil24_host_intr() is the same
value which was just validated.
