[Xen-devel] [PATCH] xen/PCI: Update ACPI Check to include SGI Ux3

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

From: root <root@xxxxxxxxxxxxxxxxxxxx>

These systems use variations of SGI3* for ID string.

Instead of adding abother set of strings do what Linux did
in commit 526018bc and look at first three letters.
