Linux kernel source tree
b259d137e9
Alex pointed out that we don't pass a level hint to the TLBI instruction when handling a stage-2 permission fault, even though the walker does at some point have the level information in its hands. Rework stage2_update_leaf_attrs() so that it can optionally return the level of the updated pte to its caller, which can in turn be used to provide the correct TLBI level hint.

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.
