mainlining shenanigans

Teng Qin says: ==================== These patches add support that allows bpf programs attached to perf events to read the address values recorded with the perf events. These values are requested by specifying sample_type with PERF_SAMPLE_ADDR when calling perf_event_open(). The main motivation for these changes is to support building memory or lock access profiling and tracing tools. For example on Intel CPUs, the recorded address values for supported memory or lock access perf events would be the access or lock target addresses from PEBS buffer. Such information would be very valuable for building tools that help understand memory access or lock acquire pattern. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |

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.
