Pull parisc updates from Helge Deller:
"Lots of small fixes and enhancements, most noteably:
- Many TLB and cache flush optimizations (Dave)
- Fixed HPMC/crash handler on 64-bit kernel (Dave and myself)
- Added alternative infrastructre. The kernel now live-patches itself
for various situations, e.g. replace SMP code when running on one
CPU only or drop cache flushes when system has no cache installed.
- vmlinuz now contains a full copy of the compressed vmlinux file.
This simplifies debugging the currently booted kernel.
- Unused driver removal (Christoph)
- Reduced warnings of Dino PCI bridge when running in qemu
- Removed gcc version check (Masahiro)"

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.
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.
