2019-11-20regulator: tps6105x: add optional devicetree supportSven Van Asbroeck
Tell the regulator framework to retrieve regulator init data from the 'regulator' subnode, or from the parent mfd device's platform data. Example: i2c0 { tps61052@33 { compatible = "ti,tps61052"; reg = <0x33>; regulator { regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; regulator-always-on; }; }; }; Tree: next-20191118 Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Link: https://lore.kernel.org/r/20191119154611.29625-3-TheSven73@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>
2019-11-20tps6105x: add optional devicetree supportSven Van Asbroeck
This driver currently requires platform data to specify the operational mode and regulator init data (in case of regulator mode). Optionally specify the operational mode by looking at the name of the devicetree child node. Example: put chip in regulator mode: i2c0 { tps61052@33 { compatible = "ti,tps61052"; reg = <0x33>; regulator { regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; regulator-always-on; }; }; }; Tree: linux-next Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Link: https://lore.kernel.org/r/20191119154611.29625-2-TheSven73@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>

2019-11-20s390/cpumf: Adjust registration of s390 PMU device driversThomas Richter
Linux-next commit titled "perf/core: Optimize perf_init_event()" changed the semantics of PMU device driver registration. It was done to speed up the lookup/handling of PMU device driver specific events. It also enforces that only one PMU device driver will be registered of type PERF_EVENT_RAW. This change added these line in function perf_pmu_register(): ... + ret = idr_alloc(&pmu_idr, pmu, max, 0, GFP_KERNEL); + if (ret < 0) goto free_pdc; + + WARN_ON(type >= 0 && ret != type); The warn_on generates a message. We have 3 PMU device drivers, each registered as type PERF_TYPE_RAW. The cf_diag device driver (arch/s390/kernel/perf_cpumf_cf_diag.c) always hits the WARN_ON because it is the second PMU device driver (after sampling device driver arch/s390/kernel/perf_cpumf_sf.c) which is registered as type 4 (PERF_TYPE_RAW). So when the sampling device driver is registered, ret has value 4. When cf_diag device driver is registered with type 4, ret has value of 5 and WARN_ON fires. Adjust the PMU device drivers for s390 to support the new semantics required by perf_pmu_register().

2019-11-20KVM: nVMX: Assume TLB entries of L1 and L2 are tagged differently if L0 use EPTLiran Alon
Since commit 1313cc2bd8f6 ("kvm: mmu: Add guest_mode to kvm_mmu_page_role"), guest_mode was added to mmu-role and therefore if L0 use EPT, it will always run L1 and L2 with different EPTP. i.e. EPTP01!=EPTP02. Because TLB entries are tagged with EP4TA, KVM can assume TLB entries populated while running L2 are tagged differently than TLB entries populated while running L1. Therefore, update nested_has_guest_tlb_tag() to consider if L0 use EPT instead of if L1 use EPT.
