Hi Mike,
as we discussed with Kevin in my arm-soc pull request I should send
these two patches separately and directly to you.
I have rebased them on 3.11-rc2 which is the kernel version you have in
your clk-next branch. Thanks for pulling them.
Thanks,

To iterate over all policies we currently iterate over all CPUs and
then get the policy for each of them. Let's use the newly created

cpufreq_policy_cpu per-cpu variables are used for storing cpu that manages a cpu

cpufreq_policy_list is a list of active policies. We do remove policies from
this list when all CPUs belonging to that policy are removed. But during suspend
we don't really free a policy struct as it will be used again during resume. And
so we didn't remove it from cpufreq_policy_list as well..

For the implementation (patch 1/3), need fill buffer as full as

For the caller (patch 2/3, 3/3), need check the return value of

If 'hc' is false, 'al' will never be false, either (only need check
"irdp->qlen != rdp->qlen_lazy' when 'rdp->nxtlist' existance).
Recommend to improve the related code, like the diff below.
--diff begin
diff --git a/kernel/rc
According to the comment above rcu_cpu_has_callbacks(): "If there are
no callbacks, all of them are deemed to be lazy".
So when both 'hc' and 'al' are false, '*all_lazy' should be true, not
false.

If this patch is correct, better to let CPU_ONLINE and CPU_DOWN_FAILED
share the same code.
And do we need a comment "/* fall through */" between CPU_UP_CANCELED
and CPU_DOWN_FAILED (or it is another bug, need a 'break' statement) ?
At last, also better to let CPU_DOWN_PREPARE and CPU_UP_CANCELE

As the up/down_read_non_owner() API has been brought back from the
dead, and has a single user (bcache), this module now breaks -rt, as
-rt has no API for non owner rwsems.
Now I looked at the code for bcache, and I don't see a way to fix it.
Perhaps there is, but I don't see it. Thus, I decided
In related functions, they have already had tag 'free', so use 'goto'
instead of 'break' to keep one (not multiple) style in each function.
Also remove useless checking 'err' code or move it to related 'if' code
block.

Unfortunately xics_init() and kvm_cpu_init() both use base_init(). So
depending on the order randomly determined by the compiler, xics_init()
may initialised see kvm->nrcpus as 0 and not setup any of the icp

have an explicit include of linux/file.h instead of relying upon
