The code path for M-Mode linux that disables interrupts for other contexts
was missed when refactoring __plic_toggle().
Since the new version caches updates to the state for the primary context,
its use in this codepath is no longer desireable even if it could be made
correct.
Replace the calls to __plic_toggle() with a loop that simply disables all
of the interrupts in groups of 32 with a direct mmio write.

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.
