To properly handle memory and branch samples, this patch divides into
two functions for generating samples: arm_spe__synth_mem_sample() is for
synthesizing memory and TLB samples; arm_spe__synth_branch_sample() is
to synthesize branch samples.
Arm SPE backend decoder has passed virtual and physical address through
packets, the address info is stored into the synthesize samples in the
function arm_spe__synth_mem_sample().
Committer notes:
Fixed this:

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.
