    s390: mark __cpacf_query() as __always_inline · 5c8e10f8
    Jiri Kosina authored
    arch/s390/kvm/kvm-s390.c calls on several places __cpacf_query() directly,
    which makes it impossible to meet the "i" constraint for the asm operands
    (opcode in this case).
    
    As we are now force-enabling CONFIG_OPTIMIZE_INLINING on all
    architectures, this causes a build failure on s390:
    
       In file included from arch/s390/kvm/kvm-s390.c:44:
       ./arch/s390/include/asm/cpacf.h: In function '__cpacf_query':
       ./arch/s390/include/asm/cpacf.h:179:2: warning: asm operand 3 probably doesn't match constraints
         179 |  asm volatile(
             |  ^~~
       ./arch/s390/include/asm/cpacf.h:179:2: error: impossible constraint in 'asm'
    
    Mark __cpacf_query() as __always_inline in order to fix that, analogically
    how we fixes __cpacf_check_opcode(), cpacf_query_func() and scpacf_query()
    already.
