Documentation: hyperv: Update VMBus doc with new features and info
...
Starting in the 6.15 kernel, VMBus interrupts are automatically
assigned away from a CPU that is being taken offline. Add documentation
describing this case.
Also add details of Hyper-V behavior when the primary channel of
a VMBus device is closed as the result of unbinding the device's
driver. This behavior has not changed, but it was not previously
documented.

Documentation: hyperv: Improve synic and interrupt handling description
...
Current documentation does not describe how Linux handles the synthetic
interrupt controller (synic) that Hyper-V provides to guest VMs, nor how
VMBus or timer interrupts are handled. Add text describing the synic and
reorganize existing text to make this more clear.
