Broadcom Keypad controller is used to interface a SoC with a matrix-type keypad device. The keypad controller supports multiple row and column lines. A key can be placed at each intersection of a unique row and a unique column. The keypad controller can sense a key-press and key-release and report the event using an interrupt to the CPU.

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).

On some Dell Latitudes we fail to identify presence of trackstick unless we reset the device. The issue is quite benign as we do perform reset in alps_init(), so the trackstick ends up working, but mouse name reported to userspace is not accurate. In order to fix the issue while avoiding the additional lengthy reset we move the resrt to alps_detect() and keep the discovered state to be used later in alps_init().

KEY_HOME is the key to go back to the beginning of the line, not the key to get into an overview mode, as Windows does. GNOME can already make use of the Windows key on multiple form factors, and other desktop environments can use it depending on the form factor. Using "Windows" as the emitted key also means that the keycode sent out matches the symbol on the key itself. So switch KEY_HOME to KEY_LEFTMETA ("Windows" key).

Merge tag 'trace-fixes-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull ftrace fixes from Steven Rostedt: "During testing Sedat Dilek hit a "suspicious RCU usage" splat that pointed 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" * tag 'trace-fixes-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: x86/tlb/trace: Do not trace on CPU that is offline tracing: Add condition check to RCU lockdep checks

When taking a CPU down for suspend and resume, a tracepoint may be called when the CPU has been designated offline.

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.
