Ilias Apalodimas f046fff8bc efi/libstub: measure loaded initrd info into the TPM
In an effort to ensure the initrd observed and used by the OS is
the same one that was meant to be loaded, which is difficult to
guarantee otherwise, let's measure the initrd if the EFI stub and
specifically the newly introduced LOAD_FILE2 protocol was used.

Modify the initrd loading sequence so that the contents of the initrd
are measured into PCR9.  Note that the patch is currently using
EV_EVENT_TAG to create the eventlog entry instead of EV_IPL.  According
to the TCP PC Client specification this is used for PCRs defined for OS
and application usage.

README

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.
