Use GSO to workaround a rare TSO bug on some chips. This hardware
bug may be triggered when the TSO header size is greater than 80
bytes. When this condition is detected in a TSO packet, the driver
will use GSO to segment the packet to workaround the hardware bug.
Thanks to Juergen Kreileder <jk@blackdown.de> for reporting the
problem and collecting traces to help debug the problem.
And thanks to Herbert Xu <herbert@gondor.apana.org.au> for providing
the GSO mechanism that happens to be the perfect workaround for this
problem.

I wasn't paranoid enough in verifying GSO information. A bogus gso_segs
could upset drivers as much as a bogus header would. Let's reset it in
the per-protocol gso_segment functions.
I didn't verify gso_size because that can be verified by the source of
the dodgy packets.

AT91 CF updates, mostly for power management:
- Add suspend/resume methods to the AT91 CF driver, disabling
non-wakeup IRQs during system suspend. The card detect IRQ
serves as a wakeup event source.
- Convert the driver to the more-current "platform_driver" style.
So inserting or removing a CF card will wake the system, unless that
has been disabled by updating the sysfs file; and there will be no
more warnings about spurious IRQs during suspend/resume cycles.

The patch below cleans up the pcmcia code a bit on the IRQ side (I did

and also adds a warning and passes back the correct information when a

Expose example and tool source files in the Documentation/ directory in
their own files instead of being buried (almost hidden) in readme/txt files.
This will make them more visible/usable to users who may need
to use them, to developers who may need to test with them, and
to janitors who would update them if they were more visible.
Also, if any of these possibly should not be in the kernel tree at
all, it will be clearer that they are here and we can discuss if
they should be removed.
