Mauro Carvalho Chehab f34f67292b scripts: get_abi.pl: precompile what match regexes 
In order to earn some time during matches, pre-compile regexes.

Before this patch:
	$ time ./scripts/get_abi.pl undefined |wc -l
	6970

	real	0m54,751s
	user	0m54,022s
	sys	0m0,592s

Afterwards:

	$ time ./scripts/get_abi.pl undefined |wc -l
	6970

	real	0m5,888s
	user	0m5,310s
	sys	0m0,562s

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.
