[PATCH] restore _OS object to "Linux" for ia64

[Alex Williamson <alex.williamson@hp.com>]

   A recent change to ACPI made the _OS object falsely report the OS as
"Microsoft Windows NT".  This seems like a slippery slope, and I'd
rather not go down it for ia64.  I think all of the ia64 OEMs are
involved enough with Linux that this isn't necessary and the change
limits the options should ACPI firmware need to make an OS specific work
around.  The patch below will make all ia64 boxes report a default _OS
of "Linux".  Thanks,

	Alex
