The CMTP flags should be clearly restricted to valid ones. So this puts
extra checks in place to ensure this.

The current kernel options do not make it clear which modules are for
Bluetooth Classic (BR/EDR) and which are for Bluetooth Low Energy (LE).

To make it really clear, introduce BT_BREDR and BT_LE options with
proper dependencies into the different modules. Both new options
default to y to not create a regression with previous kernel config
files.

This patch removes the null test on ctrl. ctrl is initialized at the
beginning of the function to &session->ctrl. Since session is
dereferenced prior to the null test, session must be a valid pointer,
and &session->ctrl cannot be null.

The following Coccinelle script is used for detecting the change:

@r@
expression e,f;
identifier g,y;
statement S1,S2;
@@

*e = &f->g
<+...
 f->y

*if (e != NULL || ...)
 S1 else S2

The L2CAP socket structure does not contain the address information
anymore. They need to be accessed through the L2CAP channel.

Pull VFS updates from Al Viro,

Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).

7kloc removed.

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.
