Tom de Vries b46632ca16 [gdb/testsuite] Add xfail in gdb.arch/i386-pkru.exp
On a x86_64-linux machine with pkru register, I run into:
...
(gdb) PASS: gdb.arch/i386-pkru.exp: set pkru value
info register pkru^M
pkru           0x12345678          305419896^M
(gdb) FAIL: gdb.arch/i386-pkru.exp: read value after setting value
...

This is a regression due to kernel commit e84ba47e313d ("x86/fpu: Hook up PKRU
onto ptrace()").  This is fixed by recent kernel commit 4a804c4f8356
("x86/fpu: Allow PKRU to be (once again) written by ptrace.").

The regression occurs for kernel versions v5.14-rc1 (the first tag containing
the regression) up to but excluding v6.2-rc1 (the first tag containing the fix).

Fix this by adding an xfail for the appropriate kernel versions.

Tested on x86_64-linux.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
