[Xen-devel] [PATCH] tweak memory error correction field in the SMBIOS data

[Paolo Bonzini <pbonzini@xxxxxxxxxx>]

Microsoft's Windows logo certified hardware requires single- or
multi-bit ECC; since the SVVP certification runs the same test
on the guest, Xen domains will currently fail it.

This patch fixes it.
