Subject: KVM: enlarge number of possible CPUID leaves
From: Andre Przywara <[email protected]>
commit 73c1160ce377d8fc6d84cb630ebf9658808bec49 upstream.
Currently the number of CPUID leaves KVM handles is limited to 40.
My desktop machine (AthlonII) already has 35 and future CPUs will
expand this well beyond the limit. Extend the limit to 80 to make
room for future processors.
