btw., i had to do these conflict resolutions:

    Conflicts:
        arch/x86/include/asm/page.h
        arch/x86/include/asm/pgtable.h
        arch/x86/mach-voyager/voyager_smp.c
        arch/x86/mm/fault.c

and this in kmemcheck:

    Merge branch 'x86/headers' into kmemcheck
    
    Conflicts:
        arch/x86/include/asm/pgtable.h
    
    Merged into:
    
        arch/x86/include/asm/pgtable_types.h
    
Plus the fixlet below.
