Subject[PATCH v3 03/10] s390/cpacf: mark scpacf_query() as __always_inline
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.

If it is enabled for s390, the following error is reported:

In file included from arch/s390/crypto/des_s390.c:19:
./arch/s390/include/asm/cpacf.h: In function 'cpacf_query':
./arch/s390/include/asm/cpacf.h:170:2: warning: asm operand 3 probably doesn't match constraints
asm volatile(
./arch/s390/include/asm/cpacf.h:170:2: error: impossible constraint in 'asm'
