This fixes the slow-down of VM running with pci-passthrough, since some MTRR range changed from MTRR_TYPE_WRBACK to MTRR_TYPE_UNCACHABLE. Memory in the 0K-640K range was incorrectly treated as uncacheable. Fixes: f7bfb57b3e89ff89c0da9f93dedab89f68d6ca27 Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=107561 Cc: qemu-stable@nongnu.org Signed-off-by: Alexis Dambricourt <alexis.dambricourt@gmail.com> [Use correct BZ for "Fixes" annotation. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
