In MSM8994-V1, for unknown reasons the pmu percpu interrupt was incorrectly connected to the corresponding CPU in the other cluster. To workaround this problem, it was decided that the cti could be used to trigger the percpu pmu interrupt to the right cpu which actually caused the event and can handle it. This patch implements this workaround. Change-Id: I732ad77ed2529a54b85c51b3fadcc53d93d70279 Signed-off-by: Rohit Vaswani <rvaswani@codeaurora.org>
