vga: Cleanup dirty logging (Jan Kiszka)

In theory, there are no more quirks in the KVM slot management that
requires dirty log start/stop all over the place. We just have to start
the logging each time the mapping may have changed. This patch drops
vga_dirty_log_stop for both standard and cirrus VGA. It also reverts...

Missing cirrus_invalidate_region() in cirrus_do_copy() (Brian Kress)

After doing a video to video copy, cirrus_do_copy() in cirrus_vga.c does a

However at this point the blt has already been done so it seems like this call...

KVM: Coalesced MMIO support

MMIO exits are more expensive in KVM or Xen than in QEMU because they
involve, at least, privilege transitions. However, MMIO write

Good examples of this include VGA pixel operations when in a planar...
