Re: [Xen-ia64-devel] [Patch 0/3] Disable ACPI SRAT, SLIT on dom0 <take 2>

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, Keir, Alex and all

I'm sorry very much.
Please ignore these patches.
generate_acpi_checksum() is needed by libxc on ia64.
So these patch is not complete...

Best Regards,

Akio Takebe
