Linus Torvalds c3bf8a1440 perf/urgent contains 3 fixups: 
- Intel/PT: filters could crash the kernel
 
  - Intel: default disable the PMU for SMM, some new-ish EFI firmware has
    started using CPL3 and the PMU CPL filters don't discriminate against
    SMM, meaning that CPL3 (userspace only) events now also count EFI/SMM
    cycles.
 
  - Fixup for perf_event_attr::sig_data

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.

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.
