The patch changes the parsing of:
callq *0x8(%rbx)
from:
0.26 │ → callq *8
to:
0.26 │ → callq *0x8(%rbx)
in this case an address is followed by a register, thus one can't parse
only the address.
Committer testing:
1) run 'perf record sleep 10'
2) before applying the patch, run:
perf annotate --stdio2 > /tmp/before
3) after applying the patch, run:
perf annotate --stdio2 > /tmp/after
4) diff /tmp/before /tmp/after:

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.
