perf/core improvements and fixes:
User visible changes:
- Support s390 jump instructions in perf annotate (Christian Borntraeger)
- When failing to setup multiple events (e.g. '-e irq_vectors:*'), state
which one caused the failure (Yao Jin)
- Various fixes for pipe mode, where the output of 'perf record' is
written to stdout instead of to a perf.data file, fixing workloads
such as: (David Carrillo-Cisneros)
$ perf record -o - noploop | perf inject -b > perf.data
$ perf record -o - noploop | perf annotate
Infrastructure changes:
- Simplify ltrim() implementation (Arnaldo Carvalho de Melo)
- Use ltrim() and rtrim() in places where ad-hoc equivalents were being
used (Taeung Song)

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.
