commit b4453cc8a7ebbd45436a8cd3ffeaa069ceac146f upstream. The code for emulating deprecated instructions has two related structures: struct insn_emulation_ops and struct insn_emulation, where each struct insn_emulation_ops is associated 1-1 with a struct insn_emulation. It would be simpler to combine the two into a single structure, removing the need for (unconditional) dynamic allocation at boot time, and simplifying some runtime pointer chasing. This patch merges the two structures together. There should be no functional change as a result of this patch.

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.
