    Impact: generic addr <-> pcpu ptr conversion macros
    
    There's nothing arch specific about x86 __addr_to_pcpu_ptr() and
    __pcpu_ptr_to_addr().  With proper __per_cpu_load and __per_cpu_start
    defined, they'll do the right thing regardless of actual layout.
    
    Move these macros from arch/x86/include/asm/percpu.h to mm/percpu.c
    and allow archs to override it as necessary.
