[RFC][Raring][SRU][Pull Request] Bluetooth update for LP#1065400 and LP#1209124

[Jesse Sung]

Hi,

Currently the broadcom firmware loader in the kernel loads firmware
with inserting
certain delay between two commands. This approach does not work well with new
platforms(eg. Lynx Point LP). Kernel 3.10 introduced an approach to
send hci commands synchronously. The firmware loader can make sure
that previous command is completed
before sending out another. It works better and there's no need to
worry about if
the delay is too small or too large.

There's also a demand of supporting intel 7260 bluetooth module. It is
supported by
kernel 3.10, and the support depends on the approach mentioned above.

Related changes and some bug fixes are cherry-picked from 3.10 in this
pull request.
Basically these are all clean merges, and the broadcom firmware
loader, which is an
ubuntu sauce currently, is ported to use this new approach.

This is already tested on several machines, but since the amount of
commits is quite large,
I'd like to have your comments on this. If this looks good for SRU,
I'll do another pull request against quantal.

Thanks.
