The generic vtime_task_switch() implementation gets built only if __ARCH_HAS_VTIME_TASK_SWITCH is not defined, but requires an architecture to implement arch_vtime_task_switch() callback at the same time, which is confusing. Further, arch_vtime_task_switch() is implemented for 32-bit PowerPC architecture only and vtime_task_switch() generic variant is rather superfluous. Simplify the whole vtime_task_switch() wiring by moving the existing generic implementation to PowerPC.

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 reStructuredText 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.
