To transport the information required for secure boot a new IPL report
will be created at boot time. It will be written to memory right after
the IPL parameter block. To work with the IPL report a couple of
additional structure definitions are added the the uapi/ipl.h header.

The IPL parameter block is used as an interface between Linux and
the machine to query and change the boot device and boot options.
To be able to create IPL parameter block in user space and pass it
as segment to kexec provide an uapi header with proper structure
definitions for the block.
