[ Upstream commitda0f622b34] As kaslr_offset() is architecture dependent and also may not be defined by all architectures, when zeroing out unused weak functions, do not check against kaslr_offset(), but instead check if the address is within the kernel text sections. If KASLR added a shift to the zeroed out function, it would still not be located in the kernel text. This is a more robust way to test if the text is valid or not.

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.
