Hall" Subject: [patch 0/6] timekeeping: Cure the signed/unsigned wreckage Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org This series addresses the recently reintroduced signed vs. unsigned wreckage by cleaning up the whole call chain instead of just making a simple s64 -> u64 'fix' at one point and keeping the rest signed, which eventually led to the unintended signed conversion and brought back an issue that was fixed a year ago already. Here is the queue: timekeeping: Force unsigned clocksource to nanoseconds conversions timekeeping: Make the conversion call chain consistently unsigned timekeeping: Get rid of pointless typecasts These three patches are definitely urgent material timekeeping: Use mul_u64_u32_shr() instead of open coding it Can wait for 4.11, but for sanity reasons it should go into 4.10 [RFD] timekeeping: Provide optional 128bit math This is material for discussion. I'm not sure if we want to do that at all, but it addresses the insanities of long time scheduled out VMs. [RFD] timekeeping: Get rid of cycle_t This one cannot be merged right away as there are further cycles_t users in next. I merily added it for reference and it can be done around rc1 time by running a coccinelle script. Thanks, tglx
