2014-07-10serial: lpc32xx uart module can't do consoleArnd Bergmann
Every uart driver that provides a console driver needs to be built-in for the console code to work, we get a build error for modular console drivers. This changes the SERIAL_HS_LPC32XX_CONSOLE symbol to depend on the SERIAL_HS_LPC32XX driver being built-in, just like we do for all the other uart drivers.

2014-07-10dm mpath: fix IO hang due to logic bug in multipath_busyJun'ichi Nomura
Commit e80991773 ("dm mpath: push back requests instead of queueing") modified multipath_busy() to return true if !pg_ready(). pg_ready() checks the current state of the multipath device and may return false even if a new IO is needed to change the state. Bart Van Assche reported that he had multipath IO lockup when he was performing cable pull tests. Analysis showed that the multipath device had a single path group with both paths active, but that the path group itself was not active. During the multipath device state transitions 'queue_io' got set but nothing could clear it. Clearing 'queue_io' only happens in __choose_pgpath(), but it won't be called if multipath_busy() returns true due to pg_ready() returning false when 'queue_io' is set. As such the !pg_ready() check in multipath_busy() is wrong because new IO will not be sent to multipath target and the multipath state change won't happen. That results in multipath IO lockup. The intent of multipath_busy() is to avoid unnecessary cycles of dequeue + request_fn + requeue if it is known that the multipath device will requeue. Such "busy" situations would be: - path group is being activated - there is no path and the multipath is setup to requeue if no path Fix multipath_busy() to return "busy" early only for these specific situations.

2014-07-10dm io: fix a race condition in the wake up code for sync_ioJoe Thornber
There's a race condition between the atomic_dec_and_test(&io->count) in dec_count() and the waking of the sync_io() thread. If the thread is spuriously woken immediately after the decrement it may exit, making the on stack io struct invalid, yet the dec_count could still be using it. Fix this race by using a completion in sync_io() and dec_count().

2014-07-10dm: allocate a special workqueue for deferred device removalMikulas Patocka
The commit 2c140a246dc ("dm: allow remove to be deferred") introduced a deferred removal feature for the device mapper. When this feature is used (by passing a flag DM_DEFERRED_REMOVE to DM_DEV_REMOVE_CMD ioctl) and the user tries to remove a device that is currently in use, the device will be removed automatically in the future when the last user closes it. Device mapper used the system workqueue to perform deferred removals. However, some targets (dm-raid1, dm-mpath, dm-stripe) flush work items scheduled for the system workqueue from their destructor. If the destructor itself is called from the system workqueue during deferred removal, it introduces a possible deadlock - the workqueue tries to flush itself. Fix this possible deadlock by introducing a new workqueue for deferred removals. We allocate just one workqueue for all dm targets. The ability of dm targets to process IOs isn't dependent on deferred removal of unused targets, so a deadlock due to shared workqueue isn't possible. Also, cleanup local_init() to eliminate potential for returning success on failure.
