If anyone has any objections, please let me know. ------------------ From: Dexuan Cui commit 238064f13d057390a8c5e1a6a80f4f0a0ec46499 upstream. The pci-hyperv driver's channel callback hv_pci_onchannelcallback() is not really a hot path, so we don't need to mark it as a perf_device, meaning with this patch all HV_PCIE channels' target_cpu will be CPU0.
