commit 40d5bb87377a599d0405af765290f28aaa6abb1e upstream.
Two touchpad/trackstick combos are currently not behaving properly.
They define a mouse emulation collection, as per Win8 requirements,
but also define a separate mouse collection for the trackstick.
The way the kernel currently treat the collections is that it
merges both in one device. However, given that the first mouse
collection already defines X,Y and left, right buttons, when
mapping the events from the second mouse collection, hid-multitouch
sees that these events are already mapped, and simply ignores them.
To be able to report events from the tracktick, add a new quirked
class for it, and manually add the 2 devices we know about.

commit e72455b898ac678667c5674668186b4670d87d11 upstream.
Fix for non-working buttons on knock-off USB dongles for Sony
controllers. These USB dongles are used to connect older Sony DA/DS1/DS2
controllers via USB and are common on Amazon, AliExpress, etc. Without
the patch, the square, X, and circle buttons do not function. These
dongles used to work prior to kernel 4.10 but removing the global DS3
report fixup in commit e19a267b99 ("HID: sony: DS3 comply to Linux gamepad
spec") exposed the problem.
Many people reported the problem on the Ubuntu forums and are working
around the problem by falling back to the 4.9 hid-sony driver.
The problem stems from these dongles incorrectly reporting their button
count as 13 instead of 16. This patch fixes up the report descriptor by
changing the button report count to 16 and removing 3 padding bits.

[ Upstream commit d8ef4b38cb69d907f9b0e889c44d05fc0f890977 ]
This reverts commit 9a9e97b2f1 ("cgroup: Add memory barriers to plug
cgroup_rstat_updated() race window").
The commit was added in anticipation of memcg rstat conversion which needed
synchronous accounting for the event counters (e.g. oom kill count). However,
the conversion didn't get merged due to percpu memory overhead concern which
couldn't be addressed at the time.
Unfortunately, the patch's addition of smp_mb() to cgroup_rstat_updated()
meant that every scheduling event now had to go through an additional full
barrier and Mel Gorman noticed it as 1% regression in netperf UDP_STREAM test.
There's no need to have this barrier in tree now and even if we need
synchronous accounting in the future, the right thing to do is separating that
out to a separate function so that hot paths which don't care about
synchronous behavior don't have to pay the overhead of the full barrier. Let's
revert.
