Thread-topic: [PATCH] Fixed legacy issues when extends number of vcpus > 32
User-agent: Microsoft-Entourage/
Let me think about these. For patch 1 I think we can perhaps do more work in
the loop which matches vlapic identifiers, and thus avoid needing a
"temporary cpumask" to remember matches. For patch 2 I've been intending to
throw away the VMX VPID logic and share the SVM logic, as it flushes TLBs no
more than the VMX logic and doesn't suffer the same problems with VPID/ASID
