Hi,
I am looking at in cpufreq.c
__cpufreq_governor(policy, CPUFREQ_GOV_STOP);
up_write(&policy->rwsem);
__cpufreq_governor(policy, CPUFREQ_GOV_POLICY_EXIT);
down_write(&policy->rwsem);
Why do we need to unlock the lock before calling CPUFREQ_GOV_POLICY_EXIT.
Wont this result in a race condition when 2 cpus are calling policy
exit, one after another during governor switch?

Hi,
These are a few cleanups around idlestat commandline options while I was
working on reformating the report.
Regards,
Amit
Amit Kucheria (9):
'verbose' option isn't used anywhere, remove it
Sort options in alphabetic order of the single-char options
Adding missing 'duration' option in long_options
Specify which options need arguments and which don't to help
getopt_long()
Stick to -d for debug according to widely used convention
Make getopt_long handling more robust
struct option long_options doesn't need to be global
improve help - show all available options
idledebug? When did we ever call it that?

When trying to build gcc-runtime_linaro-4.9.bb for qemuarm, I get the
following error:
===
[...]

The problem reared its head with 4.8 about a month ago, but I am not sure
which update to my OE tree broke it.
Host is gentoo with profile: default/linux/amd64/13.0/desktop/gnome
(multilib) is enabled.
My gut feel is it is a host gcc problem?

gcc -v

Non-linaro gcc-runtime-4.9.0.bb builds fine (as did 4.8).
Any help is appreciated.
