    [PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing conf1 · 0637a70a
    Andi Kleen authored
    Some buggy systems can machine check when config space accesses
    happen for some non existent devices.  i386/x86-64 do some early
    device scans that might trigger this. Allow pci=noearly to disable
    this. Also when type 1 is disabling also don't do any early
    accesses which are always type1.
    
    This moves the pci= configuration parsing to be a early parameter.
    I don't think this can break anything because it only changes
    a single global that is only used by PCI.
