commit 1c813ce030 upstream
ptrace (through PTRACE_SETREGSET with NT_X86_XSTATE) ultimately calls
copy_uabi_from_kernel_to_xstate(). In preparation for eventually handling
PKRU in copy_uabi_to_xstate, pass in a pointer to the PKRU location.

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.
