Linux kernel source tree
f9f16dfbe7
The perf tool searches a memory event name under the folder '/sys/devices/cpu/events/', this leads to the limitation for the selection of a memory profiling event which must be under this folder. Thus it's impossible to use any other event as memory event which is not under this specific folder, e.g. Arm SPE hardware event is not located in '/sys/devices/cpu/events/' so it cannot be enabled for memory profiling. This patch changes to search folder from '/sys/devices/cpu/events/' to '/sys/devices', so it give flexibility to find events which can be used for memory profiling.

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.
