    SubjectRe: [PATCH 0/4] x86: UV runtime bios calls
    From
    Date
    Hi, Russ,

    This seems to include a extension to EFI runtime services. Why not also
    discuss that on UEFI forum? You can get some information about UEFI
    forum from http://www.uefi.org/.

    Best Regards,
    Huang Ying
