The arm architecture supports breakpoint accounting but it doesn't support breakpoint overflow signal handling. The current code uses the same checking helper, thus it disables both testings (bp_account and bp_signal) for arm platform. For handling two testings separately, this patch adds a dedicated checking helper is_supported() for breakpoint accounting testing, thus it allows supporting breakpoint accounting testing on arm platform; the old helper test__bp_signal_is_supported() is only used to checking for breakpoint overflow signal testing.

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.
