2017-04-28IB/SA: Modify SA to implicitly cache Class Port infoDasaratharaman Chandramouli
SA will query and cache class port info as part of its initialization. SA will also invalidate and refresh the cache based on specific events. Callers such as IPoIB and CM can query the SA to get the classportinfo information. Apart from making the caller code much simpler, this change puts the onus on the SA to query and maintain classportinfo much like how it maitains the address handle to the SM.

2017-04-28blk-mq: unify hctx delay_work and run_workJens Axboe
The only difference between ->run_work and ->delay_work, is that the latter is used to defer running a queue. This is done by marking the queue stopped, and scheduling ->delay_work to run sometime in the future. While the queue is stopped, direct runs or runs through ->run_work will not run the queue. If we combine the handlers, then we need to handle two things: 1) If a delayed/stopped run is scheduled, then we should not run the queue before that has been completed. 2) If a queue is delayed/stopped, the handler needs to restart the queue. Normally a run of a queue with the stopped bit set would be a no-op. Case 1 is handled by modifying a currently pending queue run to the deadline set by the caller of blk_mq_delay_queue(). Subsequent attempts to queue a queue run will find the work item already pending, and direct runs will see a stopped queue as before. Case 2 is handled by adding a new bit, BLK_MQ_S_START_ON_RUN, that tells the work handler that it should clear a stopped queue and run the handler.

This allows the driver to pass in struct ieee80211_tx_status directly. Make ieee80211_tx_status_noskb a wrapper around it. As with ieee80211_tx_status_noskb, there is no _ni variant of this call, because it probably won't be needed. Even if the driver won't provide any extra status info other than what's in struct ieee80211_tx_info already, it can optimize status reporting this way by passing in the station pointer.

2017-04-27bridge: add per-port broadcast flood flagMike Manning
Support for l2 multicast flood control was added in commit b6cb5ac8331b ("net: bridge: add per-port multicast flood flag"). It allows broadcast as it was introduced specifically for unknown multicast flood control. But as broadcast is a special case of multicast, this may also need to be disabled. For this purpose, introduce a flag to disable the flooding of received l2 broadcasts. This approach is backwards compatible and provides flexibility in filtering for the desired packet types.

2017-04-27rhashtable: Cap total number of entries to 2^31Herbert Xu
When max_size is not set or if it set to a sufficiently large value, the nelems counter can overflow. This would cause havoc with the automatic shrinking as it would then attempt to fit a huge number of entries into a tiny hash table. This patch fixes this by adding max_elems to struct rhashtable to cap the number of elements. This is set to 2^31 as nelems is not a precise count. This is sufficiently smaller than UINT_MAX that it should be safe. When max_size is set max_elems will be lowered to at most twice max_size as is the status quo.

2017-04-27KVM: mark requests that need synchronizationPaolo Bonzini
kvm_make_all_requests() provides a synchronization that waits until all kicked VCPUs have acknowledged the kick. This is important for KVM_REQ_MMU_RELOAD as it prevents freeing while lockless paging is underway. This patch adds the synchronization property into all requests that are currently being used with kvm_make_all_requests() in order to preserve the current behavior and only introduce a new framework. Removing it from requests where it is not necessary is left for future patches. Signed-off-by: Radim Krčmář <rkrcmar@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-04-27KVM: add explicit barrier to kvm_vcpu_kickAndrew Jones
kvm_vcpu_kick() must issue a general memory barrier prior to reading vcpu->mode in order to ensure correctness of the mutual-exclusion memory barrier pattern used with vcpu->requests. While the cmpxchg called from kvm_vcpu_kick(): kvm_vcpu_kick kvm_arch_vcpu_should_kick kvm_vcpu_exiting_guest_mode cmpxchg implies general memory barriers before and after the operation, that implication is only valid when cmpxchg succeeds. We need an explicit barrier for when it fails, otherwise a VCPU thread on its entry path that reads zero for vcpu->requests does not exclude the possibility the requesting thread sees !IN_GUEST_MODE when it reads vcpu->mode. kvm_make_all_cpus_request already had a barrier, so we remove it, as now it would be redundant.

2017-04-27KVM: mark requests that do not need a wakeupRadim Krčmář
Some operations must ensure that the guest is not running with stale data, but if the guest is halted, then the update can wait until another event happens. kvm_make_all_requests() currently doesn't wake up, so we can mark all requests used with it. First 8 bits were arbitrarily reserved for request numbers. Most uses of requests have the request type as a constant, so a compiler will optimize the '&'. An alternative would be to have an inline function that would return whether the request needs a wake-up or not, but I like this one better even though it might produce worse assembly.
