    ARM: add PROC_VTABLE and PROC_TABLE macros · e209950f
    Russell King authored
    Allow the way we access members of the processor vtable to be changed
    at compile time.  We will need to move to per-CPU vtables to fix the
    Spectre variant 2 issues on big.Little systems.
    
    However, we have a couple of calls that do not need the vtable
    treatment, and indeed cause a kernel warning due to the (later) use
    of smp_processor_id(), so also introduce the PROC_TABLE macro for
    these which always use CPU 0's function pointers.
