Subject: [PATCH 4.9 03/66] Drivers: hv: vmbus: do not mark HV_PCIE as perf_device
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dexuan Cui <decui@...rosoft.com>
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.
