Masahiro Yamada d83623c5ea s390: mark __cpacf_check_opcode() and cpacf_query_func() as __always_inline
Commit e60fb8bf68 ("s390/cpacf: mark scpacf_query() as __always_inline")
was not enough to make sure to meet the 'i' (immediate) constraint for the
asm operands.

With CONFIG_OPTIMIZE_INLINING enabled, Laura Abbott reported error
with gcc 9.1.1:

  In file included from arch/s390/crypto/prng.c:29:
  ./arch/s390/include/asm/cpacf.h: In function 'cpacf_query_func':
  ./arch/s390/include/asm/cpacf.h:170:2: warning: asm operand 3 probably doesn't match constraints
    170 |  asm volatile(
        |  ^~~
  ./arch/s390/include/asm/cpacf.h:170:2: error: impossible constraint in 'asm'

Add more __always_inline to force inlining.

Fixes: 9012d01166 ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
