Linux kernel modifications for the Kernel Hacking exam
4b3e71e9a3
Add support for loading keys from the PLPKS on pseries machines, with the "ibm,plpks-sb-v1" format. The object format is expected to be the same, so there shouldn't be any functional differences between objects retrieved on powernv or pseries. Unlike on powernv, on pseries the format string isn't contained in the device tree. Use secvar_ops->format() to fetch the format string in a generic manner, rather than searching the device tree ourselves. (The current code searches the device tree for a node compatible with "ibm,edk2-compat-v1". This patch switches to calling secvar_ops->format(), which in the case of OPAL/powernv means opal_secvar_format(), which searches the device tree for a node compatible with "ibm,secvar-backend" and checks its "format" property. These are equivalent, as skiboot creates a node with both "ibm,edk2-compat-v1" and "ibm,secvar-backend" as compatible strings.)

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.
