    [PATCH] i386: Don't delete cpu_devs data to identify different x86
    types in late_initcall

    In arch/i386/cpu/common.c there is:
    cpu_devs[X86_VENDOR_INTEL]
    cpu_devs[X86_VENDOR_CYRIX]
    cpu_devs[X86_VENDOR_AMD]
    ...
    They are all filled with data early.
    The data (struct) got set to NULL  for all, but Intel in different
    late_initcall (exit_cpu_vendor) calls.
    I don't see what sense this makes at all, maybe something that got
    forgotten with the HOTPLUG_CPU extenstions?

    Please check/review whether initdata, cpuinitdata is still ok and
    this still works with HOTPLUG_CPU and without, it should...
