Another revision of this patchset critical for GK20A to operate. Previous attempts were exclusively using either TTM's regular page allocator or the DMA API one. Both have their advantages and drawbacks: the page allocator is fast but requires explicit synchronization on non-coherent architectures, whereas the DMA allocator always returns coherent memory, but is also slower, creates a

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
