The /dev/vhci ops don't refer to the module and so it is possible to
unload the module while the file descriptor is in use. This was an
accidental removal after the cleanup.

After the removal of the module parameter for setting the minor number,
this variable became unused. So just remove it.

Remove the empty ioctl which just returns -EINVAL. vfs_ioctl() will
return -ENOTTY instead, but I doubt that any application will notice
the difference :)

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

The virtual driver implements fasync and ioctl support, but it is not used
and unneeded due to its constraints via the Bluetooth core layer. So too
just make the driver simpler, remove support for both of them.

The BKL push down added some BKL into the open callback of the virtual
driver. The driver is really simple and need no such locking and so just
remove it.

The virtual driver still uses a home grown way of waiting for events and
so just replace it with wait_event_interruptible. And while at it remove
the useless access_ok() checks.

Allowing to specify a specific misc minor number for the virtual driver
is pretty much useless and nobody is using this feature. So just remove
it and use MISC_DYNAMIC_MINOR all the time.

With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to
allow debugging without having to recompile the kernel. This patch turns
all BT_DBG() calls into pr_debug() to support dynamic debug messages.
As a side effect all CONFIG_BT_*_DEBUG statements are now removed and
some broken debug entries have been fixed.

The Bluetooth entries for the MAINTAINERS file are a little bit too
much. Consolidate them into two entries. One for Bluetooth drivers and
another one for the Bluetooth subsystem.
Also the MODULE_AUTHOR should indicate the current maintainer of the
module and actually not the original author. Fix all Bluetooth modules
to provide current maintainer information.

Remove the llseek method given that the open method already calls

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.
Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
