    Ah, forgotten about that.

    Unfortunately the latency tracer patch doesn't compile either:

    CC kernel/latency_trace.o
    kernel/latency_trace.c:28:21: error: asm/rtc.h: No such file or directory
    kernel/latency_trace.c:63:3: error: #error Implement cycles_to_usecs.
    kernel/latency_trace.c: In function ‘____trace’:
    kernel/latency_trace.c:658: error: implicit declaration of function ‘irqs_disabled_flags’
    make[1]: *** [kernel/latency_trace.o] Error 1
