Heiko Carstens f33d663db0 checkstack: fix printed address
commit ee34db3f271cea4d4252048617919c2caafe698b upstream.

All addresses printed by checkstack have an extra incorrect 0 appended at
the end.

This was introduced with commit 677f1410e0 ("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.

README

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.
