[RFC][PATCH 0/3] staging: alarm-dev: Cleanups and compat_ioctl support (v2)

[John Stultz <john.stultz@linaro.org>]

Here is the second revision at implementing compat_ioctl support for
Android's alarm-dev driver in staging.

The first patch removes the pre-Android 1.0 _OLD ioctls, per Colin's
suggestion. Then the second patch does some refactoring to cleanup
and separate the copying of user data from the logic, and the final
patch adds the compat_ioctl support.

I've tested this with a trivial unit test compiled for both 32bit
and 64bit on a x86_64 kernel, and it looks ok, but closer review
would be appreciated to make sure I didn't break anything.

Additional feedback or thoughts would be welcome!

thanks
