[PATCH 4.19] firmware: arm_scmi: Fix device node validation for mailbox transport

by Cristian Marussi

commit 2ab4f4018cb6b8010ca5002c3bdc37783b5d28c2 upstream. When mailboxes are used as a transport it is possible to setup the SCMI transport layer, depending on the underlying channels configuration, to use one or two mailboxes, associated, respectively, to one or two, distinct, shared memory areas: any other combination should be treated as invalid. Add more strict checking of SCMI mailbox transport device node descriptors.

[PATCH v5.4.y 1/2] net_sched: add __rcu annotation to netdev->qdisc

by Zubin Mithra

From: Eric Dumazet <edumazet(a)google.com> commit 5891cd5ec46c2c2eb6427cb54d214b149635dd0e upstream. syzbot found a data-race [1] which lead me to add __rcu annotations to netdev->qdisc, and proper accessors to get LOCKDEP support.

[PATCH for 4.14, 4.19] usb: host: ohci-pxa27x: Fix and & vs | typo

by Nobuhiro Iwamatsu

From: Dan Carpenter <dan.carpenter(a)oracle.com> commit 0709831a50d31b3caf2237e8d7fe89e15b0d919d upstream. The code is supposed to clear the RH_A_NPS and RH_A_PSM bits, but it's a no-op because of the & vs | typo. This bug predates git and it was only discovered using static analysis so it must not affect too many people in real life.

[PATCH][for stable/linux-5.15.y] KVM: VMX: Move preemption timer <=> hrtimer dance to common x86

by Tudor Ambarus

From: Sean Christopherson <seanjc(a)google.com> commit 98c25ead5eda5e9d41abe57839ad3e8caf19500c upstream. Handle the switch to/from the hypervisor/software timer when a vCPU is blocking in common x86 instead of in VMX. Even though VMX is the only user of a hypervisor timer, the logic and all functions involved are generic x86 (unless future CPUs do something completely different and implement a hypervisor timer that runs regardless of mode). Handling the switch in common x86 will allow for the elimination of the pre/post_blocks hooks, and also lets KVM switch back to the hypervisor timer if and only if it was in use (without additional params). Add a comment explaining why the switch cannot be deferred to kvm_sched_out() or kvm_vcpu_block().

Values of vPMC registers are saved in sysreg files on certain occasions. These saved values don't represent the current values of the vPMC registers if the perf events for the vPMCs count events after the save. The current values of those registers are the sum of the sysreg file value and the current perf event counter value. But, when userspace reads those registers (using KVM_GET_ONE_REG), KVM returns the sysreg file value to userspace (not the sum value). Fix this to return the sum value for KVM_GET_ONE_REG.
