Condense the calculation of decompressed kernel start a little. Committer notes: before: ebp = ebx - (init_size - _end) after: eax = (ebx + _end) - init_size where in both ebx contains the temporary address the kernel is moved to for in-place decompression. The before and after difference in register state is %eax and %ebp but that is immaterial because the compressed image is not built with -mregparm, i.e., all arguments of the following extract_kernel() call are passed on the stack.

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.
