From: Joerg Roedel <joerg.roedel@xxxxxxx>

(cherry picked from commit a89c1ad270ca7ad0eec2667bc754362ce7b142be)

Currently KVM implements MC0-MC4_MISC read support. When booting Linux this
results in KVM warnings in the kernel log when the guest tries to read
MC5_MISC. Fix this warnings with this patch.
