2017-03-24IB/core: Protect against self-requeue of a cq work itemSagi Grimberg
We need to make sure that the cq work item does not run when we are destroying the cq. Unlike flush_work, cancel_work_sync protects against self-requeue of the work item (which we can do in ib_cq_poll_work).

2017-03-24i40iw: Receive netdev events post INET_NOTIFIER stateShiraz Saleem
Netdev notification events are de-registered only when all client iwdev instances are removed. If a single client is closed and re-opened, netdev events could arrive even before the Control Queue-Pair (CQP) is created, causing a NULL pointer dereference crash in i40iw_get_cqp_request. Fix this by allowing netdev event notification only after we have reached the INET_NOTIFIER state with respect to device initialization.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management fixes from Rafael Wysocki: "One of these is an intel_pstate regression fix and it is not a small change, but it mostly removes code that shouldn't be there. That code was acquired by mistake and has been a source of constant pain since then, so the time has come to get rid of it finally. We have not seen problems with this change in the lab, so fingers crossed. The rest is more usual: one more intel_pstate commit removing useless code, a cpufreq core fix to make it restore policy limits on CPU online (which prevents the limits from being reset over system suspend/resume), a schedutil cpufreq governor initialization fix to make it actually work as advertised on all systems and an extra sanity check in the cpuidle core to prevent crashes from happening if the arch code messes things up. Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Restore policy min/max limits on CPU online cpuidle: Validate cpu_dev in cpuidle_add_sysfs() cpufreq: intel_pstate: Fix policy data management in passive mode cpufreq: schedutil: Fix per-CPU structure initialization in sugov_start() cpufreq: intel_pstate: One set of global limits in active mode

2017-03-23KVM: kvm_io_bus_unregister_dev() should never failDavid Hildenbrand
No caller currently checks the return value of kvm_io_bus_unregister_dev(). This is evil, as all callers silently go on freeing their device. A stale reference will remain in the io_bus, getting at least used again, when the iobus gets teared down on kvm_destroy_vm() - leading to use after free errors. There is nothing the callers could do, except retrying over and over again. So let's simply remove the bus altogether, print an error and make sure no one can access this broken bus again (returning -ENOMEM on any attempt to access it).

However, nested VPID enable bit is set unconditionally during setup nested vmx exec controls though VPID is not exposed through nested VMX capablity. This patch fixes it by don't set nested VPID enable bit if it is disabled on L0.

2017-03-23KVM: x86: correct async page present tracepointWanpeng Li
After async pf setup successfully, there is a broadcast wakeup w/ special token 0xffffffff which tells vCPU that it should wake up all processes waiting for APFs though there is no real process waiting at the moment. The async page present tracepoint print prematurely and fails to catch the special token setup. This patch fixes it by moving the async page present tracepoint after the special token setup.

2017-03-23kvm: vmx: Flush TLB when the APIC-access address changesJim Mattson
Quoting from the Intel SDM, volume 3, section 28.3.3.4: Guidelines for Use of the INVEPT Instruction: If EPT was in use on a logical processor at one time with EPTP X, it is recommended that software use the INVEPT instruction with the "single-context" INVEPT type and with EPTP X in the INVEPT descriptor before a VM entry on the same logical processor that enables EPT with EPTP X and either (a) the "virtualize APIC accesses" VM-execution control was changed from 0 to 1; or (b) the value of the APIC-access address was changed. In the nested case, the burden falls on L1, unless L0 enables EPT in vmcs02 when L1 doesn't enable EPT in vmcs12.

2017-03-23xen/acpi: upload PM state from init-domain to XenAnkur Arora
This was broken in commit cd979883b9ed ("xen/acpi-processor: fix enabling interrupts on syscore_resume"). do_suspend (from xen/manage.c) and thus xen_resume_notifier never get called on the initial-domain at resume (it is if running as guest.) The rationale for the breaking change was that upload_pm_data() potentially does blocking work in syscore_resume(). This patch addresses the original issue by scheduling upload_pm_data() to execute in workqueue context.

Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting.
