Charlie Jenkins 0f9ad973b0 perf tests code-reading: Handle change in objdump output from binutils >= 2.41 on riscv
After binutils commit e43d876 which was first included in binutils 2.41,
riscv no longer supports dumping in the middle of instructions.

Increase the objdump window by 2-bytes to ensure that any instruction
that sits on the boundary of the specified stop-address is not cut in
half.

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 reStructuredText 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.
