When building a kernel without module support, the CONFIG_MLONGCALL option needs to be enabled in order to reach symbols which are outside of a 22-bit branch. This patch changes the autodetection in the Kconfig script to always enable CONFIG_MLONGCALL when modules are disabled and uses a far call to preempt_schedule_irq() in intr_do_preempt() to reach the symbol in all cases.

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.
