Warning information:
  MODPOST vmlinux.o
WARNING: modpost: vmlinux.o(.text+0x1e540): Section mismatch in reference from the function mpc85xx_l2ctlr_of_probe() to the function .init.text:instantiate_cache_sram()
The function mpc85xx_l2ctlr_of_probe() references
the function __init instantiate_cache_sram().
This is often because mpc85xx_l2ctlr_of_probe lacks a __init
annotation or the annotation of instantiate_cache_sram is wrong.
