![]() - Prevent unnecessary timer softirq invocations by extending the tracking of the next expiring timer in the timer wheel beyond the existing NOHZ functionality. The tracking overhead at enqueue time is within the noise, but on sensitive workloads the avoidance of the soft interrupt invocation is a measurable improvement. - The obligatory new clocksource driver for Ingenic X100 OST - The usual fixes, improvements, cleanups and extensions for newer chip variants all over the driver space. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl8pD7ITHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoRIXD/9VRiGKHIP27O0aoPj9HGFiZyY+bXbC xv5HA9CTlJjG23JTZWg13Kk26l8+mzIJoH54nMnceVDdCwPb1e7iRFgefyHOgEW4 oKpJnwqvGOA9cvAnu8Tl9oNNILUoS2k0dHDeGICMCOqqjycUoKGRPpiizsbXZ08x yOLUMktX0wtNnL6DOqOpvmfN+b3T8gO0fuNzgRcvcHZpamQxo7wN2P05mt9nmWLV zfEwyhn33Xy9toGPZfkbCYNzVSI3fkMXuMDIkLo5jOtt18i06AeUZov8Z0V7xk9B S1lu2HmP4PnX00/P7KB8LwtlhzhM/H7IxK4bxYJYlHmGcd2hJHjKdIfCg3bqo41d YmsIelukI3jLvnrB6YXyWx3mt1a8p/i3zf/+Fwqs81qV/60FXhp0zD2QnltJEEC3 INXrb93CkC5vMqOs0otizL5cPnPhTS0fMe/GhnHlsteUXlqEeJ1HU5f+j0FFaIJA h+dEPT57eJwDyuh6iWNHjvAI/HtLSBTsHC0CPWa+DxHKxzItZWpiVl+EEw5ofepX zJyf8nxq1nOMDOROCiTxdbyp4yacDk3dak/trbRZCfX9fapSuzJFzDRCM0Ums2lH lh12jR9nRZgKb5atC31UUpw4HYZfvcbj2NGr27SAx9b3hh5q6SRW8yowL8tta1lK /Afs0OhmQS5Raw== =uJnp -----END PGP SIGNATURE----- Merge tag 'timers-core-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "Time, timers and related driver updates: - Prevent unnecessary timer softirq invocations by extending the tracking of the next expiring timer in the timer wheel beyond the existing NOHZ functionality.
