SVN rev 204907 on 2010-03-09 03:30:31Z by alc
Implement AMD's recommended workaround for Erratum 383 on Family 10h
processors. With this workaround, superpage promotion can be re-enabled
under virtualization. Moreover, machine check exceptions can safely be
enabled when FreeBSD is running natively on Family 10h processors.
Most of the credit should go to Andriy Gapon for diagnosing the error and
working with Borislav Petkov at AMD to document it. Andriy also reviewed
and tested my patches.
Discussed with: jhb
