Support dumping status of Hardware Trace Macro (HTM) function via debugfs interface. Under debugfs folder "/sys/kernel/debug/powerpc/htmdump", add file "htmstatus". The interface allows only read of this file which will present the content of HTM status buffer from the hcall. The 16th offset of HTM status buffer has value for the number of HTM entries in the status buffer. Each nest htm status entry is 0x6 bytes, where as core HTM status entry is 0x8 bytes. Calculate the number of bytes to read based on this detail.

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 reStructuredText 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.
