The HPT343/345 (aka 363) is a bit of a warped device. For many setups you
need to access the other registers via BAR4 offsets. PIO is now rock
solid, DMA isn't. Unfortunately the drivers/ide hpt34x driver is
completely broken so doesn't help further debug.

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.

With PCI resource fix up for legacy hosts. We can use the same code
path to allocate IO resources and initialize host for both legacy and
native SFF hosts. Only IRQ requesting needs to be different.
Rename ata_pci_*_native_host() to ata_pci_*_sff_host(), kill all
legacy specific functions and use the renamed functions instead. This
simplifies code a lot.

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.

InfiniBand HCAs replicate multicast packets back to the QP that sent
them if that QP is attached to the destination multicast group. This
means that IPoIB multicasts are often replicated back to the receive
queue of the interface that generated them. To avoid confusing the
network stack, we drop these duplicates within the IPoIB driver.
However, there's no reason to free the skb that received the duplicate
and then immediately allocate a new skb to post to the receive queue.
We can be more efficient and just repost the same skb.

While playing with the firmware a while back, I discovered a way to
access the device's entire address space before the firmware has been
loaded.
Previously we were loading the firmware early on (during probe) so that
we could read the MAC address from the EEPROM and register a netdevice.
Now that we can read the EEPROM without having firmware, we can defer
firmware loading until later while still reading the MAC address early
on.
This has the advantage that zd1211rw can now be built into the kernel --
previously if this was the case, zd1211rw would be loaded before the
filesystem is available and firmware loading would fail.
Firmware load and other device initialization operations now happen the
first time the interface is brought up.
Some architectural changes were needed: handling of the is_zd1211b flag
was moved into the zd_usb structure, MAC address handling was obviously
changed, and a preinit_hw stage was added (the order is now: init,
preinit_hw, init_hw).

Zen Kato's device has a regulatory domain value of 0x49, which is not an
IEEE 802.11 code and is not even identified in the vendor driver.
Recent versions of the vendor driver don't even look at the regdomain
value any more, and just allow channels 1-11 everywhere. This patch
brings us more in line with that behaviour, by allowing channels 1-11
for regdomains which we don't know about.

Hi,
This is the third submission of the network driver for PS3.
The differences from the previous one are:
- renamed source file names so that their prefix can match
with the module name
- added cbe-oss-dev@ozlabs.org line for MAINTAINER file
- changed some in copyright comments
If there are no more comments, please apply for 2.6.23.

Matteo Croce reported Aironet initialization failures. They were caused by
a race in airo. airo finds a free interface name, then initializes the card
and finally registers the interface. Another device may get the same name
in the meantime.
The reason airo gets its name early is to use it in informative printks and
to name the resources it requests. The printks will be just fine without
the interface name and the resources can use the driver's name - that's
what other network drivers do anyway.
One of the talkative functions is setup_card(). It is called once before
registration and can be called later again. Let's have an empty dev->name
during the first call, so it doesn't print the ugly "airo(eth%d)" message.
