Subject: Fix an incorrect shift value when calculating the mask for the VMCS MSR
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=baa10a2e02d979c434fd54ee9d1606621ef4c5ec;p=openbsd

Fix an incorrect shift value when calculating the mask for the VMCS MSR
list storage size. Noticed when attempting to get vmm(4) to nest under
Hyper-V.
