Re: [PATCH v11 5/8] clocksource/drivers/arm_arch_timer: Simplify ACPI support code.

[Fu Wei]

Hi Thomas, Daniel,

For these  arm_arch_timer patches, do you have any other suggestion or comment?
I have deleted "skipping" in the error message.

I have prepared v12 (rebase to rc6 and on the top of IORT v11),
should I send it now (if you are OK with my arm_arch_timer patches ),
or anything I can do to improve this patchset ?

Thanks.
