Subject: [PATCH 0/4] keys: Add EFI_CERT_X509_GUID support for dbx/mokx entries


Here's my take on v5 of Eric Snowberg's patches[1]:

This series of patches adds support for EFI_CERT_X509_GUID entries [2].  It has
been expanded to not only include dbx entries but also entries in the mokx.
Additionally Eric included his patches to preload these certificate [3].

The patches can be found on the following branch:

	https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=keys-cve-2020-26541-branch

Changes:
 - I've modified the first patch in the series to fix a configuration
   problem[4][5], to move the added functions to a more logical place within the
   file and to add kerneldoc comments.
