- final batch of "non trivial" timer conversions (multi-tree dependencies,
things Coccinelle couldn't handle, etc).

- treewide conversions via Coccinelle, in 4 steps:
- DEFINE_TIMER() functions converted to struct timer_list * argument
- init_timer() -> setup_timer()
- setup_timer() -> timer_setup()
- setup_timer() -> timer_setup() (with a single embedded structure)

- deprecated timer API removals (init_timer(), setup_*timer())

- finalization of new API (remove global casts)

Bluetooth: hci_ldisc: Allow sleeping while proto locks are held.

Commit dec2c92880cc5435381d50e3045ef018a762a917 ("Bluetooth: hci_ldisc:
Use rwlocking to avoid closing proto races") introduced locks

Bluetooth: hci_ldisc: Allow sleeping while proto locks are held.

Commit dec2c92880cc5435381d50e3045ef018a762a917 ("Bluetooth: hci_ldisc:
Use rwlocking to avoid closing proto races") introduced locks in
hci_ldisc that are held while calling the proto functions. These locks
are rwlock's, and hence do not allow sleeping while they are held.
However, the proto functions that hci_bcm registers use mutexes and
hence need to be able to sleep.

In more detail: hci_uart_tty_receive() and hci_uart_dequeue() both
acquire the rwlock, after which they call proto->recv() and
proto->dequeue(), respectively. In the case of hci_bcm these point to
bcm_recv() and bcm_dequeue(). The latter both acquire the
bcm_device_lock, which is a mutex, so doing so results in a call to
might_sleep(). But since we're holding a rwlock in hci_ldisc, that
results in the following BUG (this for the dequeue case - a similar
one for the receive case is omitted for brevity):

BUG: sleeping function called from invalid context at kernel/locking/mutex.c
in_atomic(): 1, irqs_disabled(): 0, pid: 7303, name: kworker/7:3
INFO: lockdep is turned off.
CPU: 7 PID: 7303 Comm: kworker/7:3 Tainted: G W OE 4.13.2+ #17

We can't replace the mutex in hci_bcm, because there are other calls
there that might sleep. Therefore this replaces the rwlock's in
hci_ldisc with rw_semaphore's (which allow sleeping). This is a safer
approach anyway as it reduces the restrictions on the proto callbacks.
Also, because acquiring write-lock is very rare compared to acquiring
the read-lock, the percpu variant of rw_semaphore is used.

Lastly, because hci_uart_tx_wakeup() may be called from an IRQ context,
we can't block (sleep) while trying acquire the read lock there, so we
use the trylock variant.
