The asmlinkage macro has no special meaning in powerpc, and prior to this patch is used sporadically on some syscall handler definitions. On architectures that do not define asmlinkage, it resolves to extern "C" for C++ compilers and a nop otherwise. The current invocations of asmlinkage provide far from complete support for C++ toolchains, and so the macro serves no purpose in powerpc. Remove all invocations of asmlinkage in arch/powerpc. These incidentally only occur in syscall definitions and prototypes.

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.
