These changes build upon the existing Android kernel wakeup reason code to: * improve the positioning of suspend abort logging calls in suspend flow * add logging of abnormal wakeup reasons like unexpected HW IRQs and IRQs configured as both wake-enabled and no-suspend * add support for capturing deferred-processing threaded nested IRQs as wakeup reasons rather than their synchronously-processed parents Bug: 150970830 Bug: 140217217 Signed-off-by: Kelly Rossmoyer <krossmo@google.com> Change-Id: I903b811a0fe11a605a25815c3a341668a23de700
