Right now arm64 fault handling code removes pointer tags from addresses covered by TTBR0 in faults taken from both EL0 and EL1, but doesn't do that for pointers covered by TTBR1. This patch adds two helper functions is_ttbr0_addr() and is_ttbr1_addr(), where the latter one accounts for the fact that TTBR1 pointers might be tagged when tag-based KASAN is in use, and uses these helper functions to perform pointer checks in arch/arm64/mm/fault.c.

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.
