Nathan Chancellor 8360ed6745 RDS: IB: Use DEFINE_PER_CPU_SHARED_ALIGNED for rds_ib_stats 
Clang warns when two declarations' section attributes don't match.

declaration [-Wsection]

The initial definition was added in commit ec16227e14 ("RDS/IB:
Infiniband transport") and the cache aligned definition was added in
commit e6babe4cc4 ("RDS/IB: Stats and sysctls") right after. The
definition probably should have been updated in net/rds/ib.h, which is
what this patch does.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
