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.
