If your project is synchronized with the server after 2012-9-27, you can modify your board-xxx.c lock like the board-rk30-sdk.c int the commit.
Of course, if your project is such older, you have to cherry-pick the bellow commit

get_monotonic_boottime adds three nanonsecond values stored
in longs, followed by an s64. If the long values are all
close to 1e9 the first three additions can overflow and
become negative when added to the s64. Cast the first
value to s64 so that all additions are 64 bit.

In the past, a process could only see its own stats (uid-based summary,
and details).
Now we allow any process to see other UIDs uid-based stats, but still
hide the detailed stats.

commit e47f8976d8 upstream.
A quote from SPC-4: "While in the unavailable primary target port
asymmetric access state, the device server shall support those of
the following commands that it supports while in the active/optimized
state: [ ... ] d) SET TARGET PORT GROUPS; [ ... ]". Hence enable
sending STPG to a target port group that is in the unavailable state.

Don't restart lookup of more stargets in the multi-target case, just
arrange to traverse the list once, on the assumption that new targets
are always added at the end. There is no guarantee that the target will
change state in scsi_target_reap() so we can end up spinning if we
restart.

git commit c8adf9a3e8
"PCI: pre-allocate additional resources to devices only after
successful allocation of essential resources."
fails to take into consideration the optional-resources needed by children
devices while calculating the optional-resource needed by the bridge.
This can be a problem on some setup. For example, if a hotplug bridge has 8
children hotplug bridges, the bridge should have enough resources to accomodate
the hotplug requirements for each of its children hotplug bridges. Currently
this is not the case.
This patch fixes the problem.

commit 6d70a74ffd upstream.
The oem parameter image embedded in the efi variable is at an offset
from the start of the variable. However, in the failure path we try to
free the 'orom' pointer which is only valid when the paramaters are
being read from the legacy option-rom space.
Since failure to load the oem parameters is unlikely and we keep the
memory around in the success case just defer all de-allocation to devm.

commit bea1e22df4 upstream.
Fix a crash in ipoib_mcast_join_task(). (with help from Or Gerlitz)
Commit c8c2afe360 ("IPoIB: Use rtnl lock/unlock when changing device
flags") added a call to rtnl_lock() in ipoib_mcast_join_task(), which
is run from the ipoib_workqueue, and hence the workqueue can't be
flushed from the context of ipoib_stop().
In the current code, ipoib_stop() (which doesn't flush the workqueue)
calls ipoib_mcast_dev_flush(), which goes and deletes all the
multicast entries. This takes place without any synchronization with
a possible running instance of ipoib_mcast_join_task() for the same
ipoib device, leading to a crash due to NULL pointer dereference.
Fix this by making sure that the workqueue is flushed before
ipoib_mcast_dev_flush() is called. To make that possible, we move the
RTNL-lock wrapped code to ipoib_mcast_join_finish().
