clang points out that the declaration of cio_irb does not match the
definition exactly, it is missing the alignment attribute:
../drivers/s390/cio/cio.c:50:1: warning: section does not match previous declaration [-Wsection]
DEFINE_PER_CPU_ALIGNED(struct irb, cio_irb);
^
../include/linux/percpu-defs.h:150:2: note: expanded from macro 'DEFINE_PER_CPU_ALIGNED'
DEFINE_PER_CPU_SECTION(type, name, PER_CPU_ALIGNED_SECTION) \
^
../include/linux/percpu-defs.h:93:9: note: expanded from macro 'DEFINE_PER_CPU_SECTION'
extern __PCPU_ATTRS(sec) __typeof__(type) name; \
^
../include/linux/percpu-defs.h:49:26: note: expanded from macro '__PCPU_ATTRS'
__percpu __attribute__((section(PER_CPU_BASE_SECTION sec))) \
^
../drivers/s390/cio/cio.h:118:1: note: previous attribute is here
DECLARE_PER_CPU(struct irb, cio_irb);
^
../include/linux/percpu-defs.h:111:2: note: expanded from macro 'DECLARE_PER_CPU'
DECLARE_PER_CPU_SECTION(type, name, "")
^
../include/linux/percpu-defs.h:87:9: note: expanded from macro 'DECLARE_PER_CPU_SECTION'
extern __PCPU_ATTRS(sec) __typeof__(type) name
^
../include/linux/percpu-defs.h:49:26: note: expanded from macro '__PCPU_ATTRS'
__percpu __attribute__((section(PER_CPU_BASE_SECTION sec))) \
^
Use DECLARE_PER_CPU_ALIGNED() here, to make the two match.

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.
