'perf stat' displays miss ratio of L1-dcache, L1-icache, dTLB cache, iTLB cache and LL-cache. Take L1-dcache for example, miss ratio is caculated as "L1-dcache-load-misses/L1-dcache-loads". So "of all L1-dcache hits" is unsuitable to describe it, and "of all L1-dcache accesses" seems better. The comments of L1-icache, dTLB cache, iTLB cache and LL-cache are fixed in the same way.

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.
