From: Sean Christopherson Date: Thu, 4 Feb 2021 00:01:16 +0000 (-0800) Subject: KVM: x86: Move nVMX's consistency check macro to common code X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=648fc8ae37147889ab326deb24ed3354e60cd9f8;p=linux.git KVM: x86: Move nVMX's consistency check macro to common code Move KVM's CC() macro to x86.h so that it can be reused by nSVM. Debugging VM-Enter is as painful on SVM as it is on VMX. Rename the more visible macro to KVM_NESTED_VMENTER_CONSISTENCY_CHECK to avoid any collisions with the uber-concise "CC".
