[AmitP: Upstream commit 2a1f062a ("sched/headers: Move signal wakeup &
        sigpending methods from <linux/sched.h> into <linux/sched/signal.h>")
        moved few signal definitions to <linux/sched/signal.h>. Hence include
        that instead of <linux/sched.h>.

        Also folded following android-4.9 commit changes into this patch
        69279c68eed4 ("ANDROID: ARM: fiq_debugger: fix compiling for v3.3")
