2020-01-27KVM: Use vcpu-specific gva->hva translation when querying host page sizeSean Christopherson

2020-01-27mm: thp: KVM: Explicitly check for THP when populating secondary MMUSean Christopherson
Add a helper, is_transparent_hugepage(), to explicitly check whether a compound page is a THP and use it when populating KVM's secondary MMU. The explicit check fixes a bug where a remapped compound page, e.g. for an XDP Rx socket, is mapped into a KVM guest and is mistaken for a THP, which results in KVM incorrectly creating a huge page in its secondary MMU.

2020-01-27KVM: Move running VCPU from ARM to common codePaolo Bonzini
For ring-based dirty log tracking, it will be more efficient to account writes during schedule-out or schedule-in to the currently running VCPU. We would like to do it even if the write doesn't use the current VCPU's address space, as is the case for cached writes (see commit 4e335d9e7ddb, "Revert "KVM: Support vCPU-based gfn->hva cache"", 2017-05-02). Therefore, add a mechanism to track the currently-loaded kvm_vcpu struct. There is already something similar in KVM/ARM; one important difference is that kvm_arch_vcpu_{load,put} have two callers in virt/kvm/kvm_main.c: we have to update both the architecture-independent vcpu_{load,put} and the preempt notifiers. Another change made in the process is to allow using kvm_get_running_vcpu() in preemptible code. This is allowed because preempt notifiers ensure that the value does not change even after the VCPU thread is migrated.

2020-01-27KVM: Move vcpu alloc and init invocation to common codeSean Christopherson
Now that all architectures tightly couple vcpu allocation/free with the mandatory calls to kvm_{un}init_vcpu(), move the sequences verbatim to common KVM code. Move both allocation and initialization in a single patch to eliminate thrash in arch specific code. The bisection benefits of moving the two pieces in separate patches is marginal at best, whereas the odds of introducing a transient arch specific bug are non-zero.

2020-01-27ceph: use copy-from2 op in copy_file_rangeLuis Henriques
Instead of using the copy-from operation, switch copy_file_range to the new copy-from2 operation, which allows to send the truncate_seq and truncate_size parameters. If an OSD does not support the copy-from2 operation it will return -EOPNOTSUPP. In that case, the kernel client will stop trying to do remote object copies for this fs client and will always use the generic VFS copy_file_range.

In case the max_mds > 1 in MDS cluster and there is no any standby MDS and all the max_mds MDSs are in up:active state, if one of the up:active MDSs is dead, the m->m_num_laggy in kclient will be 1. Then the mount will fail without considering other healthy MDSs. There manybe some MDSs still "in" the cluster but not in up:active state, we will ignore them. Only when all the up:active MDSs in the cluster are laggy will treat the cluster as not be available. In case decreasing the max_mds, the cluster will not stop the extra up:active MDSs immediately and there will be a latency. During it the up:active MDS number will be larger than the max_mds, so later the m_info memories will 100% be reallocated.

2020-01-27qed: FW 8.42.2.0 Additional ll2 typeMichal Kalderon
LL2 queues were a limited resource due to FW constraints. This FW introduced a new resource which is a context based ll2 queue (memory on host). The additional ll2 queues are required for RDMA SRIOV. The code refers to the previous ll2 queues as ram-based or legacy, and the new queues as ctx-based. This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue.

Implement DEBUG_GET request to get debugging settings for a device. At the moment, only message mask corresponding to message level as reported by ETHTOOL_GMSGLVL ioctl request is provided. (It is called message level in ioctl interface but almost all drivers interpret it as a bit mask.) As part of the implementation, provide symbolic names for message mask bits as ETH_SS_MSG_CLASSES string set.

2020-01-27cpufreq: Avoid creating excessively large stack framesRafael J. Wysocki
In the process of modifying a cpufreq policy, the cpufreq core makes a copy of it including all of the internals which is stored on the CPU stack. Because struct cpufreq_policy is relatively large, this may cause the size of the stack frame to exceed the 2 KB limit and so the GCC complains when -Wframe-larger-than= is used. In fact, it is not necessary to copy the entire policy structure in order to modify it, however. First, because cpufreq_set_policy() obtains the min and max policy limits from frequency QoS now, it is not necessary to pass the limits to it from the callers. The only things that need to be passed to it from there are the new governor pointer or (if there is a built-in governor in the driver) the "policy" value representing the governor choice. They both can be passed as individual arguments, though, so make cpufreq_set_policy() take them this way and rework its callers accordingly. This avoids making copies of cpufreq policies in the callers of cpufreq_set_policy(). Second, cpufreq_set_policy() still needs to pass the new policy data to the ->verify() callback of the cpufreq driver whose task is to sanitize the min and max policy limits. It still does not need to make a full copy of struct cpufreq_policy for this purpose, but it needs to pass a few items from it to the driver in case they are needed (different drivers have different needs in that respect and all of them have to be covered). For this reason, introduce struct cpufreq_policy_data to hold copies of the members of struct cpufreq_policy used by the existing ->verify() driver callbacks and pass a pointer to a temporary structure of that type to ->verify() (instead of passing a pointer to full struct cpufreq_policy to it). While at it, notice that intel_pstate and longrun don't really need to verify the "policy" value in struct cpufreq_policy, so drop those check from them to avoid copying "policy" into struct cpufreq_policy_data (which allows it to be slightly smaller). Also while at it fix up white space in a couple of places and make cpufreq_set_policy() static (as it can be so).

2020-01-27thermal/drivers/cpu_cooling: Introduce the cpu idle cooling driverDaniel Lezcano
The cpu idle cooling device offers a new method to cool down a CPU by injecting idle cycles at runtime. It has some similarities with the intel power clamp driver but it is actually designed to be more generic and relying on the idle injection powercap framework. The idle injection duration is fixed while the running duration is variable. That allows to have control on the device reactivity for the user experience. An idle state powering down the CPU or the cluster will allow to drop the static leakage, thus restoring the heat capacity of the SoC. It can be set with a trip point between the hot and the critical points, giving the opportunity to prevent a hard reset of the system when the cpufreq cooling fails to cool down the CPU. With more sophisticated boards having a per core sensor, the idle cooling device allows to cool down a single core without throttling the compute capacity of several cpus belonging to the same clock line, so it could be used in collaboration with the cpufreq cooling device.

2020-01-26hv_utils: Add the support of hibernationDexuan Cui
Add util_pre_suspend() and util_pre_resume() for some hv_utils devices (e.g. kvp/vss/fcopy), because they need special handling before util_suspend() calls vmbus_close(). For kvp, all the possible pending work items should be cancelled. For vss and fcopy, some extra clean-up needs to be done, i.e. fake a THAW message for hv_vss_daemon and fake a CANCEL_FCOPY message for hv_fcopy_daemon, otherwise when the VM resums back, the daemons can end up in an inconsistent state (i.e. the file systems are frozen but will never be thawed; the file transmitted via fcopy may not be complete). Note: there is an extra patch for the daemons: "Tools: hv: Reopen the devices if read() or write() returns errors", because the hv_utils driver can not guarantee the whole transaction finishes completely once util_suspend() starts to run (at this time, all the userspace processes are frozen). util_probe() disables channel->callback_event to avoid the race with the channel callback.

2020-01-26block: allow partitions on host aware zone devicesChristoph Hellwig
Host-aware SMR drives can be used with the commands to explicitly manage zone state, but they can also be used as normal disks. In the former case it makes perfect sense to allow partitions on them, in the latter it does not, just like for host managed devices. Add a check to add_partition to allow partitions on host aware devices, but give up any zone management capabilities in that case, which also catches the previously missed case of adding a partition vs just scanning it. Because sd can rescan the attribute at runtime it needs to check if a disk has partitions, for which a new helper is added to genhd.h.
