Patch series "lib/zlib: Set of s390 DFLTCC related patches for kernel zlib".
Patches 1-7 represent a set of s390 zlib hardware support (DFLTCC) related
fixes and enhancements integrated from zlib-ng repo relevant to kernel
zlib (https://github.com/zlib-ng/zlib-ng).
Since the official zlib repository never got DFLTCC support code merged,
all the patches have been picked from zlib-ng fork (zlib data compression
library for the next generation systems). This repo contains new
optimizations and fixes not getting implemented into the official zlib
repository and falls under the same zlib License. All of the original
patches from zlib-ng were authored by Ilya Leoshkevich
<iii@linux.ibm.com>. Coding style has been preserved for future
maintainability.
Patches 1-2 should have no effect for the kernel zlib but make the code
closer to zlib-ng for future maintainability.
Only Patch 3 touches common zlib_deflate code, other patches are relevant
to s390 tree only.
Patch 8 is separate and intends to resolve an issue with kernel PPP driver
which can use kernel zlib for packet compression. Without this patch PPP
decompression can fail due to error code returned by hardware
(dfltcc_inflate) and PPP disables zlib compression for further packets.
This patch (of 8):

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.
