The recent addition of in_serving_softirq() to kconv.h results in compile failure on PREEMPT_RT because it requires task_struct::softirq_disable_cnt. This is not available if kconv.h is included from sched.h. It is not needed to include kconv.h from sched.h. All but the net/ user already include the kconv header file. Move the include of the kconv.h header from sched.h it its users. Additionally include sched.h from kconv.h to ensure that everything task_struct related is available.

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.
