If perf is to work properly with the PMU counters we have to unrevert
the revert of the PMU interrupt code commit. I have a commit to do this
(to put the slightly refactored code back actually) queued up for the

Except for CONFIG_LOCAL_TIMERS, which isn't applicable for i.MX53 with
only a single A8 core, the other config options have been verified all
turned on for the Freescale LT's v3.1 based kernel, and will be
available in the 2011.10 monthly release.

This is quite critical to ARM, not just from the point of view of
supporting the DS-5 profiling tools but OSS profiling tools like perf as
well, across silicon from different partners. Having different kernel
configurations for the different Linaro kernel trees makes the images
inconsistent and bre

Title:
Enable basic profiling & tracing options
I'm not aware of any problems like that. There used to be some problems
with FTRACE and some userspace tools, but it was mostly about symbol de-
mangling, so in other words it doesn't break anything else.
I've just spoken to Will Deacon and he has similar opinion, so yes - I'd
say let's enable all
Should these be on for all platforms or are there problems for example
with THUMB2 kernel?
