Mixing kernel and user debug hooks together is highly error-prone as it relies on all of the hooks to figure out whether the exception came from kernel or user, and then to act accordingly. Make our debug hook code a little more robust by maintaining separate hook lists for user and kernel, with separate registration functions to force callers to be explicit about the exception levels that they care about.

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.
