A driver for laptop buttons using an x86 BIOS interface that is
apparently used on quite a few laptops and seems to be originating
from Wistron.
This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000
(i.e. it can detect the laptop using DMI and it contains the
keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G
(probably can't be reliably autodetected, requires a module parameter),
adding other laptops should be easy.
In addition to reporting button presses to the input layer the driver
also allows enabling/disabling the embedded wireless NIC (using the
"Wifi" button); this is done using the same BIOS interface, so it seems
only logical to keep the implementation together. Any flexibility
possibly gained by allowing users to remap the function of the "Wifi"
button is IMHO not worth it when weighted against the necessity to run
an user-space daemon to convert button presses to wifi state changes.

Changing led state is pretty slow operation; when there are multiple
requests coming at a high rate they may interfere with normal typing.
Try optimize (skip) changing hardware state when multiple requests
are coming back-to-back.

Since the spinlock was removed from sa1100_start_tx(), the "flags"
variable becomes redundant. Remove it.

The receiver status register reports latched error conditions, which
must be cleared by writing to it. However, the data register reports
unlatched conditions which are associated with the current character.
Use the data register to interpret error status rather than the RSR.

Make sure that userspace passes in enough data when sending a MAD. We
always copy at least sizeof (struct ib_user_mad) + IB_MGMT_RMPP_HDR
bytes from userspace, so anything less is definitely invalid. Also,
if the length is less than this limit, it's possible for the second
copy_from_user() to get a negative length and trigger a BUG().

The following patch fixes a crash caused by attempting to bounce buffer

Cleaning up the hwif without knowing its previous state in pmac.c is a big
and potentially dangerous job, and there seems to be no generic code interface
that would provide either a way to properly release an hwif or to clean it up.

This entry adds needless complication to the driver as it requires the use of
global variables to be passed into via_get_info(), making things quite ugly
when we try and make this driver support multiple controllers simultaneously.
This patch removes /proc/via for simplicity.

For the four versions of hardware that we (currently) support microcode
download on, the default configuration of our receive interrupt mitigation
microcode was too aggressive, and caused unnecessary delays when pinging,
and low(er) throughput on single connection latency sensitive performance
tests.
This code adds microcode support, and sets the defaults to more reasonable
settings. It also explains the functionality in the code in more detail.
Compile and load tested, shows expected behavior for slight delay of ping
packets (1-2ms) when ucode is loaded, and decent interrupt moderation for
small packets, while maintaining good throughput.
