Subject: [PATCH] compat-wireless: add CONFIG_COMPAT_BT_SOCK_CREATE_NEEDS_KERN

An API change in the 2.6.33 timeframe made a number of bluetooth
functions require an extra parameter.  Some kernels (e.g. RHEL6)
backport that API change, and this allow us to accommodate them.

This adds CONFIG_COMPAT_BT_SOCK_CREATE_NEEDS_KERN to config.mk and
modifies an existing patch for the Bluetooth subsystem.
