s390/ctl_reg: mark __ctl_set_bit and __ctl_clear_bit as __always_inline
s390:tinyconfig fails to build with gcc 8.3.0. arch/s390/include/asm/ctl_reg.h:52:2: error: impossible constraint in 'asm' asm volatile( \ ^~~ arch/s390/include/asm/ctl_reg.h:62:2: note: in expansion of macro '__ctl_store' __ctl_store(reg, cr, cr); ^~~~~~~~~~~ s390/include/asm/ctl_reg.h:41:2: error: impossible constraint in 'asm' asm volatile( \ ^~~ arch/s390/include/asm/ctl_reg.h:64:2: note: in expansion of macro '__ctl_load' __ctl_load(reg, cr, cr); ^~~~~~~~~~ Marking __ctl_set_bit and __ctl_clear_bit as __always_inline fixes the problem.
