The entries in the .parainstructions sections are 8 byte aligned and the
corresponding C struct paravirt_patch_site makes the array offset 16
bytes.
Though the pushed entries are only using 12 bytes, __parainstructions_end
is therefore 4 bytes short.
That works by chance because it's only used in a loop:
for (p = start; p < end; p++)
But this falls flat when calculating the number of elements:
n = end - start
That's obviously off by one.
Ensure that the gap is filled and the last entry is occupying 16 bytes.
[ bp: Add the proper struct and section names. ]

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.
