process_buffer_measurement() is limited to measuring the kexec boot command line. This patch makes process_buffer_measurement() more generic, allowing it to measure other types of buffer data (e.g. blacklisted binary hashes or key hashes). process_buffer_measurement() may be called directly from an IMA hook or as an auxiliary measurement record. In both cases the buffer measurement is based on policy. This patch modifies the function to conditionally retrieve the policy defined PCR and template for the IMA hook case.

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.
