All addresses printed by checkstack have an extra incorrect 0 appended at the end. This was introduced with commit677f1410e0("scripts/checkstack.pl: don't display $dre as different entity"): since then the address is taken from the line which contains the function name, instead of the line which contains stack consumption. E.g. on s390: 0000000000100a30 <do_one_initcall>: ... 100a44: e3 f0 ff 70 ff 71 lay %r15,-144(%r15) So the used regex which matches spaces and hexadecimal numbers to extract an address now matches a different substring. Subsequently replacing spaces with 0 appends a zero at the and, instead of replacing leading spaces. Fix this by using the proper regex, and simplify the code a bit.

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.
