But in this case GCC is smart enough to notice that "base + # PLB4OPB_GESR0" will be constant, even though it's not something we can # immediately stringify into a register number. # # Segher pointed out that passing the register number to the inline asm # as a constant would be better, and in fact it fixes the build error, # presumably because it gives GCC a chance to resolve the value. # # While we're at it, change mtdcr() similarly. # # Reported-by: kernel test robot # Suggested-by: Segher Boessenkool # Signed-off-by: Michael Ellerman # Acked-by: Feng Tang # Link:
