The set of values asce_limit may be assigned with is TASK_SIZE_MAX, _REGION1_SIZE, _REGION2_SIZE and 0 as a special case if the callback was called from execve(). Do VM_BUG_ON() if asce_limit is something else. Save few CPU cycles by removing unnecessary asce_limit re-assignment in case of 3-level task and redundant PGD entry type reconstruction.

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.
