pci_enable_msi failure is a normal event so we should not print any error.
Going over the code I spotted a missing pci_disable_msi() leak when irq
allocation fails. The whole code also needed a cleanup, so I combined the
two different calls to pci_request_irq into a single call making this
look a lot better. All #ifdef CONFIG_PCI_MSI's have been removed.
Compile tested with both CONFIG_PCI_MSI enabled and disabled.

pci_enable_msi calls can fail for normal operational reasons. Driver
should not print an error message in that case. Fix a leak that leaves
msi enabled if pci_request_irq fails. We can remove CONFIG_PCI_MSI
ifdefs alltogether

The hardware must not see that is given ownership of a buffer until it is
completely written, and when the driver receives ownership of a buffer,
it must ensure that any other reads to the buffer reflect its final
state. Thus, I/O barriers are added where required.
Without this patch, I have observed GCC reordering the setting of
bdp->length and bdp->status in gfar_new_skb. Hardware reordering
was also theoretically possible.

Original patch is from Jeff Haran <jharan@brocade.com> with my minor style
fixes. His comments follow:
The first problem was in the function that configures the PHY for
autonegotiation, genmii_setup_aneg(). The original code does a
read/modify/write of the autonegotiation advertizement register (reg 4),
followed by a read/modify/write of the control register (reg 0). While
the original code follows the proper procedure as per reading the IEEE
specs, what I found is that on at least one PHY model (National DP83843)
the read of the control register comes back with the soft reset bit set
(bit 15). Because of the read/modify/write operation, this causes the
write to write a 1 back to the reset bit, which initiates a software
reset of the PHY. This software reset causes the PHY to return to its
power up state which advertizes all modes of operation, thus negating
the write to the autoneg advertizement register. The modification is to
spin reading the control register until the soft reset bit is clear
before doing the modify/write.
The second problem was in the function that configures the PHY for
forced operation, genmii_setup_forced(). The original code initiates a
software reset operation via a write of a 1 to bit 15 of the control
register (reg 0), but then proceeds to do a second write to that same
register without waiting until that reset bit is cleared by the PHY
itself (which according to the IEEE specs indicates that the PHY reset
is complete). This is a violation of how one is supposed to use this
software reset feature of these PHYs and I believe was the cause of
mysterious, difficult to reproduce link failures that we've observed on
some of our systems that use this driver. The fix is to modify the
function so that it spins waiting for the reset bit to clear after doing
the soft reset and before doing the subsequent write.

Align the PHY setup of the sky2 driver with the vendor sk98lin (10.0.4.3)
driver. The PHY register settings are mostly black magic, even with access
to the documentation it isn't clear what the right values are. The changes
are mostly comments, the code change only affects the Yukon FE (100 mbit only)
version.

It was agreed that phy-connection-type was a better name for
the interface-type property, so this patch renames it.
Also, the max-speed property name was determined too generic,
and is therefore eliminated in favour of phy-connection-type
derivation logic.

Looks like the new version of this patch has been overlooked,
so I'm resending it.
It just adapts the driver to the new IRQ API
according to what Russell has pointed out.

Turns out we have an old version of firmware that stores the mac address
in 'mac-address' as a string instead of a byte array. All versions that
use local-mac-address should have it as byte array, so no need to do

Rather than having every driver fiddle about setting its private
IRQ operations and data, provide a helper function to contain
this functionality in one place.
Arrange to remove the driver-private IRQ operations and data when
the device is removed from the driver, and remove the driver
private code to do this.
This fixes potential problems caused by drivers forgetting to
remove these hooks.

This patch creates platform_device entries for the Marvell mv64x60
ethernet controller ports, based on information contained in the
device tree.
This driver (like the other mv64x60 drivers) are unusual in that it
works on both the MIPS and PowerPC architectures. Because of that,
the drivers do not support the normal PowerPC of_platform_bus_type.
They support platform_bus_type instead.
