      Add mdr as maintainer of qla1280 driver. · 5e9772b9
      Jes Sorensen authored 
      As discussed with Mike Reed, add him as the maintainer of the qla1280
driver as I no longer have any hardware and he is actively looking
after it.

      futex: futex_find_get_task remove credentails check · 7a0ea09a
      Michal Hocko authored 
      futex_find_get_task is currently used (through lookup_pi_state) from two
contexts, futex_requeue and futex_lock_pi_atomic.  None of the paths
looks it needs the credentials check, though.  Different (e)uids
shouldn't matter at all because the only thing that is important for
shared futex is the accessibility of the shared memory.

The credentail check results in glibc assert failure or process hang (if
glibc is compiled without assert support) for shared robust pthread
mutex with priority inheritance if a process tries to lock already held
lock owned by a process with a different euid:

pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed.

The problem is that futex_lock_pi_atomic which is called when we try to
lock already held lock checks the current holder (tid is stored in the
futex value) to get the PI state.  It uses lookup_pi_state which in turn
gets task struct from futex_find_get_task.  ESRCH is returned either
when the task is not found or if credentials check fails.

futex_lock_pi_atomic simply returns if it gets ESRCH.  glibc code,
however, doesn't expect that robust lock returns with ESRCH because it
should get either success or owner died.

      USB: gadget: f_mass_storage: stale common->fsg value bug fix · b894f60a
      Michal Nazarewicz authored 
      On fsg_unbind the common->fsg pointer was not NULLed if the
unbound fsg_dev instance was the current one.  As an effect,
the incorrect pointer was preserved in all further operations
which caused do_set_interface to reference an invalid region.

This commit fixes this by raising an exception in fsg_bind
which will change the common->fsg pointer.  This also requires
an wait queue so that the thread in fsg_bind can wait till the
worker thread handles the exception.

This commit removes also a config and new_config fields of
fsg_common as they are no longer needed since fsg can be
used to determine whether function is active or not.

Moreover, this commit removes possible race condition where
the fsg field was modified in both the worker thread and
form various other contexts.  This is fixed by replacing
prev_fsg with new_fsg.  At this point, fsg is assigned only
in worker thread.

      USB: gadget: f_mass_storage: fixed fs descriptors not being updated · e5fd39d9
      Michal Nazarewicz authored 
      The full speed descriptors were copied to the usb_function structure
in the fsg_bind_config function before call to the usb_ep_autoconfig.
The usb_ep_autoconfig was called in fsg_bind using the original
descriptors.  In effect copied descriptors were not updated.

This patch changes the copy full speed descriptors after the call to
usb_op_autoconfig is performed.  This way, copied full speed
descriptors have updated values.

      USB: musb: Enable the maximum supported burst mode for DMA · c0f1f8e3
      Hema HK authored 
      Setting MUSB Burst Mode 3 automatically enables support for
lower burst modes (BURST4, BURST8, BURST16 or bursts of unspecified
length). There is no need to set these burst modes based on the
packet size. Also enable the burst mode for both mode1 and mode0.

This is a fix for buggy hardware - having the lower burst modes
enabled can potentially cause lockups of the DMA engine used in
OMAP2/3/4 chips.
