Pull parisc architecture fixes from Helge Deller:
"This patchset fixes and enforces correct section alignments for the
ex_table, altinstructions, parisc_unwind, jump_table and bug_table
which are created by inline assembly.
Due to not being correctly aligned at link & load time they can
trigger unnecessarily the kernel unaligned exception handler at
runtime. While at it, I switched the bug table to use relative
addresses which reduces the size of the table by half on 64-bit.
We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
from HP-UX, which now trigger build-issues with glibc. We can simply
remove them.
Most of the patches are tagged for stable kernel series.
Summary:
- Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc
build issues
- Fix section alignments for ex_table, altinstructions, parisc unwind
table, jump_table and bug_table
- Reduce size of bug_table on 64-bit kernel by using relative
pointers"

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.
