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

>Summary:
>    On some ia64 NUMA machine, we cannot boot dom0.
>    This issue is caused by different infomation LSAPIC and SRAT.
>    Xen-ia64 modify LSAPIC IDs of dom0, but it does not modify SRAT.
>
>    Currently, credit scheduler does not consider NUMA system.
>    And Xen-ia64 pass raw ACPI SRAT, SLIT infomation to dom0.
>    If xen pass NUMA infomation to dom0, dom0 cannot move properly
>    because vcpus can migrate and memory mapping is virtualized.
>    So we decide disabling SRAT, SLIT of dom0 as first step of NUMA work.
