Currently in validate_extra_context() we assert both that the extra data pointed to by the EXTRA_CONTEXT is 16 byte aligned and that it immediately follows the struct _aarch64_ctx providing the terminator for the linked list of contexts in the signal frame. Since struct _aarch64_ctx is an 8 byte structure which must be 16 byte aligned these cannot both be true. As documented in sigcontext.h and implemented by the kernel the extra data should be at the next 16 byte aligned address after the terminator so fix the validation to match.

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.
