The size of the incoming frame is not correctly checked.
The RxMaxSize register (0xDA) does not work as expected and incoming
frames whose size exceeds the MTU actually end spanning multiple
descriptors. The first Rx descriptor contains the size of the whole
frame (or some garbage in its place). The driver does not expect
something above the space allocated to the current skb and crashes
loudly when it issues a skb_put.
The fix contains two parts:
- disable hardware Rx size filtering: so far it only proved to be able
to trigger some new fancy errors;
- drop multi-descriptors frame: as the driver allocates MTU sized Rx
buffers, it provides an adequate filtering.
As a bonus, wrong descriptors were not returned to the asic after their
processing.

Some time ago, GAS was fixed to bring the .spillpsp directive in line
with the Intel assembler manual (there was some disagreement as to
whether or not there is a built-in 16-byte offset). Unfortunately,
there are two places in the kernel where this directive is used in
handwritten assembly files and those of course relied on the "buggy"
behavior. As a result, when using a "fixed" assembler, the kernel
picks up the UNaT bits from the wrong place (off by 16) and randomly
sets NaT bits on the scratch registers. This can be noticed easily by
looking at a coredump and finding various scratch registers with
unexpected NaT values. The patch below fixes this by using the
.spillsp directive instead, which works correctly no matter what
assembler is in use.

is not necessary, and prevents preemption occuring.

I noticed this typo when trying to compile a kernel which had
CONFIG_HOTPLUG turned off. In that case, __devinit is no longer a
no-op and the compiler then detects a section-conflict. Fix by using
__devinitdata instead of __devinit.
Same patch also submitted by Darren Williams to fix compilation error
using sim_defconfig (which has CONFIG_HOTPLUG=n).

Updates to the wbsd driver.
* Fix to handle DAT3 card detection.
* Fixed bug which could cause large writes to stall in FIFO mode.
* Plug 'n Play support. In most cases you need ACPI PNP for this to work.
* Uses generic DMA API (ISA dependency removed).
