48e5ecae69 amd8111e: Fix rx return code
The amd8111e rx poll routine currently mishandles the case when we
process exactly the number of packets specified in the budget.

This patch is basically as suggested by David Miller.

f49d81a899 regulator: Build on non-ARM platforms
When the regulator API was merged it was added to the separate Kconfig
which ARM uses for drivers but not the generic one in drivers/.  Since
there is nothing ARM-specific about the API add it there too.

e8b3b5e9f5 sata_sil24: configure max read request size to 4k
Due to request posting limitations, bandwidth of sil3132 is limited to
around 120MB/s with the minimum pci-e payload size (128bytes) which is
used by most consumer systems.  However, write throughput can be
slightly (~3%) increased by increasing the max read requeset size.
Configure it to 4k which is the maximum supported.  This optimization
is also done by SIMG's windows driver.

c77a036bec ahci: Add support for Promise PDC42819
Add an appropriate entry for the Promise PDC42819 controller. It has an
AHCI mode and so far works correctly with board_ahci.

This chip is found on Promise's FastTrak TX2650 (2 port) and TX4650 (4 port)
software-based RAID cards (for which there is a binary driver, t3sas) and
can be found on some motherboards, for example the MSI K9A2 Platinum,
which calls the chip a Promise T3 controller.

Although this controller also supports SAS devices, its default bootup mode
is AHCI and the binary driver has to do some magic to get the chip into the
appropriate mode to drive SAS disks.

Seeing as no documentation is provided by Promise, adding this entry to the
ahci driver allows the controller to be useful to people as a SATA
controller (with no ill effects on the system if a SAS disk is connected -
probing of the port just times out with "link online but device
misclassified"), without having to resort to using the binary driver. Users
who require SAS or the proprietary software raid can get this functionality
using the binary driver.

There you go. Yes, it is a genuine problem, if the device's eeprom is screwed really up.

07b5f6a6fd via-velocity: use driver string instead of dev->name before register_netdev()
This patch corrects a message bug in the via-velocity driver which
bothered me for some time.

The messages printed during device init look like the following:

[    8.486422] eth%d: set value of parameter Wake On Lan options to 0
                  ^^!
[    8.487340] eth0: VIA Networking Velocity Family Gigabit Ethernet Adapter

Note the unresolved format string.

dev->name is unavailable before register_netdev, so use
dev_driver_string(&pdev->dev), which is also consistent with other
drivers.

"char *devname" parameters had to be converted to "const char *devname" to
be consistent with dev_driver_string return value.
