Subject: " Change size of node ids from u8 to u16 fixup" causes early panic in __build_all_zonelists

One of my test systems didn't boot with latest git-x86.
I bisected it down to f1321f875910172bcc3e1f302fe145a9e4d3bdf7

With later patches the fault seemed to happen even earlier before
other initialization messages.

    x86: Change size of node ids from u8 to u16 fixup
    Change the size of node ids for X86_64 from 8 bits to 16 bits
    to accomodate more than 256 nodes.
    Introduce a "numanode_t" type for x86-generic usage.
