Previously dev2 device was used for both external PS/2 mouse and internal
trackstick device (if available). This change introduces dev3 device which
is used for external PS/2 mouse data and dev2 is now used only for
trackstick.
In case that trackstick is not present dev2 is not created, so userspace
does not see non existent device in system.
Because laptops with ALPS devices often do not use i8042 active
multiplexing all data (from touchpad, trackstick and external PS/2 mouse)
come to one port. So it is not possible to know if external PS/2 mouse is
connected or not. In most cases external PS/2 mouse is not connected so
driver will create dev3 input device after first bare PS/2 packet will be
received. So there will not be "ghost" input device.
This change also helps in identifying possible problems in future if driver
decides to report 6-bytes trackstick packets as 3-bytes bare PS/2 (data
will be reported to dev3 instead dev2).

move the resrt to alps_detect() and keep the discovered state to be used

out a real bug. During suspend and resume the tlb_flush tracepoint is
called when the CPU is going offline. As the CPU has been noted as offline,
RCU is ignoring that CPU, which means that it can not use RCU protected
locks. When tracepoints are activated, they require RCU locking, and
if RCU is ignoring a CPU that runs a tracepoint, there is a chance that
the tracepoint could cause corruption.
The solution was to change the tracepoint into a TRACE_EVENT_CONDITION()
which allows us to check a condition to determine if the tracepoint
should be called or not. If the condition is not met, the rcu protected
code will not be executed. By adding the condition
"cpu_online(smp_processor_id())", this will prevent the RCU protected
code from being executed if the CPU is marked offline.
After adding this, another bug was discovered. As RCU checks rcu callers,
if a rcu call is not done, there is no check (obviously). We found that
tracepoints could be added in RCU ignored locations and not have lockdep
complain until the tracepoint is activated. This missed places where
tracepoints were added in places they should not have been. To fix this,
code was added in 3.18 that if lockdep is enabled, any tracepoint will
still call the rcu checks even if the tracepoint is not enabled. The bug
here, is that the check does not take the CONDITION into account. As the
condition may prevent tracepoints from being activated in RCU ignored
areas (as the one patch does), we get false positives when we enable
lockdep and hit a tracepoint that the condition prevents it from being
called in a RCU ignored location. The fix for this is to add the
CONDITION to the rcu checks, even if the tracepoint is not enabled.

The trace_tlb_flush() tracepoint can be called when a CPU is going offline.
When a CPU is offline, RCU is no longer watching that CPU and since the
tracepoint is protected by RCU, it must not be called. To prevent the
tlb_flush tracepoint from being called when the CPU is offline, it was
converted to a TRACE_EVENT_CONDITION where the condition checks if the
CPU is online before calling the tracepoint.
Unfortunately, this was not enough to stop lockdep from complaining about
it. Even though the RCU protected code of the tracepoint will never be
called, the condition is hidden within the tracepoint, and even though the
condition prevents RCU code from being called, the lockdep checks are
outside the tracepoint (this is to test tracepoints even when they are not
enabled).
Even though tracepoints should be checked to be RCU safe when they are not
enabled, the condition should still be considered when checking RCU.

While commit 7e36ef8205 ("IB/core: Temporarily disable
ex_query_device uverb") is correct as it makes the extended
QUERY_DEVICE uverb (which came as part of commit 5a77abf9a9
("IB/core: Add support for extended query device caps") and commit
860f10a799 ("IB/core: Add flags for on demand paging support")) not
available to userspace, it doesn't address the initial issue regarding
ib_copy_to_udata() [1][2].
Additionally, further discussions around this new uverb seems to
conclude it would require a different data structure than the one
currently described in <rdma/ib_user_verbs.h> [3].
Both of these issues require a revert of the changes, so this patch
partially reverts commit 8cdd312cfe ("IB/mlx5: Implement the ODP
capability query verb") and commit 860f10a799 ("IB/core: Add flags
for on demand paging support") and fully reverts commit 5a77abf9a9
("IB/core: Add support for extended query device caps").

There is no point in queueing EV_SYN/SYN_DROPPED on clock type change when
there are no events in the client's queue and doing so confuses tests in
libinput package, so let's not do that.

Kim Phillips reported following build failure.
LD init/built-in.o
mm/built-in.o: In function `free_pages_prepare':
mm/page_alloc.c:770: undefined reference to `.kernel_map_pages'
mm/built-in.o: In function `prep_new_page':
mm/page_alloc.c:933: undefined reference to `.kernel_map_pages'
mm/built-in.o: In function `map_pages':
mm/compaction.c:61: undefined reference to `.kernel_map_pages'
make: *** [vmlinux] Error 1
Reason for this problem is that commit 031bc5743f
("mm/debug-pagealloc: make debug-pagealloc boottime configurable")
forgot to remove the old declaration of kernel_map_pages() for some
architectures. This patch removes them to fix build failure.
