[Xen-devel] Request to backport 23511:450f1d198e1e to testing branches.

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

c/s 23511:450f1d198e1e prevents cache flushing on AMD Valencia CPUs.

The result of not having this changeset, which we see on our new
hardware, is that HVM operations proceed at a glacial pace. (1 minute
for HVM bios to start, 3 minutes between booting memtest and it actually
starting to test memory.  Attempting to install windows gets very boring
very quickly.)

The patch applies cleanly to xen-4.1-testing.
