From 302a3c0f2757ae1a3e7df3f9fa1f20e2214ab945 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Sun, 17 Feb 2013 11:30:44 -0800 Subject: Drivers: hv: vmbus: Use the new infrastructure for delivering VMBUS interrupts Use the infrastructure for delivering VMBUS interrupts using a special vector. With this patch, we can now properly handle the VMBUS interrupts that can be delivered on any CPU. Also, turn on interrupt load balancing as well. This patch requires the infrastructure that was implemented in the patch: X86: Handle Hyper-V vmbus interrupts as special hypervisor interrupts Signed-off-by: K. Y.
