In case a security flaw is found in a version of firmware, the device
offers a way to disallow the loading an older firmware.
This patch provides a vendor extension to nl80211 to enable this
feature.

The device allows to do Packet Traffic Arbitration (PTA or also Coex)
with other RF chips.
Currently, there is no API to manage the PTA parameters. This patch
provides a vendor extension to nl80211 to change the PTA parameters.

In the next commit, we will have to compute the PS timeout without
changing the power save status of the device. This patch introduces
wfx_get_ps_timeout() for that job and make wfx_update_pm() relies on it.

Applied to cgroup/for-5.8.

Why does your misc device need to be in a .h file?

Compared to v1, this fixes some incorrect injections of VINTR that happen
on kvm/queue while running nested guests, and it clarifies the code
that handles INT_CTL. The most important part here is the first three
patches, which further cleanup event injection and remove another race
between inject_
Instead of calling kvm_event_needs_reinjection, track its
future return value in a variable. This will be useful in

Now that the int_ctl field is stored in svm->nested.ctl.int_ctl, we can
use it instead of vcpu->arch.hflags to check whether L2 is running
in V_INTR_MASKING mode.

In preparation for nested SVM save/restore, store all data that matters
from the VMCB control area into svm->nested. It will then become part
of the nested SVM state that is saved by KVM_SET_NESTED_STATE and
restored by KVM_GET_NESTED_STATE, just like the cached vmcs12 for nVMX.

When restoring SVM nested state, the control state cache in svm->nested
will have to be filled, but the save state will not have to be moved
into svm->vmcb. Therefore, pull the code that handles the control area
into a separate function.

Restore the INT_CTL value from the guest's VMCB once we've stopped using
it, so that virtual interrupts can be injected as requested by L1.
V_TPR is up-to-date however, and it can change if the guest writes to CR8,
so keep it.

Similar to VMX, the state that is captured through the currently available
IOCTLs is a mix of L1 and L2 state, dependent on whether the L2 guest was
running at the moment when the process was interrupted to save its state.
In particular, the SVM-specific state for nested virtualization includes
th
The authoritative state does not come from the VMCB once in guest mode,
but KVM_SET_NESTED_STATE can still perform checks on L1's provided SVM
controls because we get them from userspace.
Therefore, split out a function to do them.

The control state changes on every L2->L0 vmexit, and we will have to
serialize it in the nested state. So keep it up to date in svm->nested.ctl
and just copy them back to the nested VMCB in nested_svm_vmexit.

This bit was added to nested VMX right when nested_run_pending was
introduced, but it is not yet there in nSVM. Since we can have pending
events that L0 injected directly into L2 on vmentry, we have to transfer
them into L1's queue.
For this to work, one important change is required: svm_complete
