Clearing cpenable special register for a task without changing coprocessor owner for the coprocessors that were enabled will result in coprocessor context flush and immediate reload at the next attempt to access this coprocessor if it happens before the context switch. Avoid it by only clearing cpenable special register if coprocessor_release_all is called for the current task. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
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.
