From 6c62985d576c8a816f528c39204207b9f449d923 Mon Sep 17 00:00:00 2001 From: Waiman Long Date: Mon, 20 Feb 2017 13:36:03 -0500 Subject: x86/paravirt: Change vcp_is_preempted() arg type to long The cpu argument in the function prototype of vcpu_is_preempted() is changed from int to long. That makes it easier to provide a better optimized assembly version of that function. For Xen, vcpu_is_preempted(long) calls xen_vcpu_stolen(int), the downcast from long to int is not a problem as vCPU number won't exceed 32 bits.
