Andi Kleen c35be33486 perf/x86/intel: Hide TSX events when RTM is not supported 
commit 58ba4d5a25 upstream.

0day testing reported a perf test regression on Haswell systems without
RTM. Commit a5df70c35 hides the in_tx/in_tx_cp attributes when RTM is not
available, but the TSX events are still available in sysfs. Due to the
missing attributes the event parser fails on those files.

Don't show the TSX events in sysfs when RTM is not available on
Haswell/Broadwell/Skylake.

Fixes: a5df70c354 (perf/x86: Only show format attributes when supported)

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
