Gerald BAEZA adb97f18b4 libperf: Fix alignment trap with xyarray contents in 'perf stat' 
[ Upstream commit d9c5c08341 ]

Following the patch 'perf stat: Fix --no-scale', an alignment trap
happens in process_counter_values() on ARMv7 platforms due to the
attempt to copy non 64 bits aligned double words (pointed by 'count')
via a NEON vectored instruction ('vld1' with 64 bits alignment
constraint).

This patch sets a 64 bits alignment constraint on 'contents[]' field in
'struct xyarray' since the 'count' pointer used above points to such a
structure.

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
