Bluetooth: Fix hidp disconnect deadlocks and lost wakeup
Partial revert of commit
aabf6f89. When the hidp session thread
was converted from kernel_thread to kthread, the atomic/wakeups
were replaced with kthread_stop. kthread_stop has blocking semantics
which are inappropriate for the hidp session kthread. In addition,
the kthread signals itself to terminate in hidp_process_hid_control()
- it cannot do this with kthread_stop().
Lastly, a wakeup can be lost if the wakeup happens between checking
for the loop exit condition and setting the current state to
TASK_INTERRUPTIBLE. (Without appropriate synchronization mechanisms,
the task state should not be changed between the condition test and
the yield - via schedule() - as this creates a race between the
wakeup and resetting the state back to interruptible.)

cgroup: Add generic cgroup subsystem permission checks
Rather than using explicit euid == 0 checks when trying to move
tasks into a cgroup via CFS, move permission checks into each
specific cgroup subsystem. If a subsystem does not specify a
'allow_attach' handler, then we fall back to doing our checks
the old way.
Use the 'allow_attach' handler for the 'cpu' cgroup to allow
non-root processes to add arbitrary processes to a 'cpu' cgroup
if it has the CAP_SYS_NICE capability set.
This version of the patch adds a 'allow_attach' handler instead
of reusing the 'can_attach' handler. If the 'can_attach' handler
is reused, a new cgroup that implements 'can_attach' but not
the permission checks could end up with no permission checks
at all.

netfilter: adding the original quota2 from xtables-addons
The original xt_quota in the kernel is plain broken:
- counts quota at a per CPU level
(was written back when ubiquitous SMP was just a dream)
- provides no way to count across IPV4/IPV6.
This patch is the original unaltered code from:

the driver will now register an otg notifier callback and listen
to transceiver events for AC/USB plug-in events instead. This would
normally be used by not specifying is_xx_online callbacks and
not specifying any irqs so the state machine is completely driven

incoming ERTM data or else the connection will go down.
Within the socket layer, an skb that does not fit in the socket
receive buffer will be temporarily stored. When the socket is read
from, that skb will be placed in the receive buffer if possible. Once
adequate buffer space becomes available, the L2CAP core is informed
