Linux kernel build fails since 4.8
cc1 -O2 consolemap.c
drivers/char/consolemap.c:654:647: error: 'asm' operand requires impossible
reload
seems to be due to this movhi<mode>_reg_reg split out of the *movhi insns.
Oleg, I think it time to re-unify those. Doing an experimental resurrection of
the r,r reload constraints seems to fix it, but without knowing the impacts on
your T-bit combine optimizations...
