    Subject[PATCH 00/12] [GIT PULL] tracing: fixes


    This patch set contains all fixes. Some of the fixes are to get
    rid of warnings, but I think getting rid of warnings is a good thing
    during a merge window.

    What's different about this and my last pull request:

    1) I removed the two patches that were not bug fixes and put them
    in my queue for 2.6.41/3.1/2.8.1

    2) I added two patches, one that was a bug fix that caused a
    triple fault when PROVE_RCU was set, and the other that caused
    problems with truncating 64bit words in the trace events.

    3) I pulled out Masami's kprobe stack trace fix because it failed
    on other archs. My last push request, I did compile test other
    archs, but I only used the default config. This time, I enabled
    tracing as well (doing it both with and without tracing enabled)
    and when tracing was enabled, I detected the problem with the lack
    of save_stack_trace_regs() in other archs.

    I tested this on x86_64 and x86_32 as well as compiled tested for
    the following archs, with and without tracing enabled:

    alpha, arm, blackfin, ia64, parsic, ppc, ppc64, sparc

    The following had failures for other reason (failed without this
    patch set):

    cris, cris32, m68k, mips64, mips32, parsic64, sh, xtensa, uml.
