A clk_disable on gate clocks would hold a global
spinlock and it would wait for a halt_delay. In some
race conditions(due to longer delays for gate clocks)
if any other CPU would also invoke a clk_disable then
it could result in a spinlock lockup. Avoid this by
moving the gcc_usb3_phy_pipe_clk clk to branch clock.

During global reclaim, the nr_reclaimed passed to vmpressure includes the
pages reclaimed from slab. But the corresponding scanned slab pages is
not passed. There is an impact to the vmpressure values because of this.
While moving from kernel version 3.18 to 4.4, a difference is seen in the
vmpressure values for the same workload resulting in a different behaviour
of the vmpressure consumer. One such case is of a vmpressure based
lowmemorykiller. It is observed that the vmpressure events are received
late and less in number resulting in tasks not being killed at the right
time. The following numbers show the impact on reclaim activity due to
the change in behaviour of lowmemorykiller on a 4GB device. The test
launches a number of apps in sequence and repeats it multiple times.

This is a regression introduced by commit 6b4f7799c6 ("mm: vmscan:
invoke slab shrinkers from shrink_zone()").
So do not consider reclaimed slab pages for vmpressure calculation. The
reclaimed pages from slab can be excluded because the freeing of a page by
slab shrinking depends on each slab's object population, making the cost
model (i.e. scan:free) different from that of LRU. Also, not every
shrinker accounts the pages it reclaims. But ideally the pages reclaimed
from slab should be passed to vmpressure, otherwise higher vmpressure
levels can be triggered even when there is a reclaim progress. But
accounting only the reclaimed slab pages without the scanned, and adding
something which does not fit into the cost model just adds noise to the
vmpressure values.

At the end of a window period, if the reclaimed pages is greater than
scanned, an unsigned underflow can result in a huge pressure value and
thus a critical event. Reclaimed pages is found to go higher than scanned
because of the addition of reclaimed slab pages to reclaimed in
shrink_node without a corresponding increment to scanned pages. Minchan
Kim mentioned that this can also happen in the case of a THP page where
the scanned is 1 and reclaimed could be 512.

Matt reported that we have a NULL pointer dereference
in ppp_pernet() from ppp_connect_channel(),
i.e. pch->chan_net is NULL.
This is due to that a parallel ppp_unregister_channel()
could happen while we are in ppp_connect_channel(), during
which pch->chan_net set to NULL. Since we need a reference
to net per channel, it makes sense to sync the refcnt
with the life time of the channel, therefore we should
release this reference when we destroy it.

SDE and the GPU have different requirements for the SMMU backends - the
SDE generates its own iova addresses and needs special support for DMA
buffers and the GPU does its own IOMMU operations. Add a shim layer to
aspace to break out the address generation and call the appropriate
SMMU functions. There is probably consolidation that can be done, but for
now this is the best way to deal with the two use cases.
