commit 7bac98707f65b93bf994ef4e99b1eb9e7dbb9c32 upstream. Define and export OBJSIZE variable for "size" tool from binutils to be used in architecture specific Makefiles (naming the variable just "SIZE" would be too risky). In particular this tool is useful to perform checks that early boot code is not using bss section (which might have not been zeroed yet or intersects with initrd or other files boot loader might have put right after the linux kernel).

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.
