[PATCH v3 0/4] keys: Add EFI_CERT_X509_GUID support for dbx/mokx entries

[David Howells]

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:

ver #3:
 - Rolled in changes from Eric to fix conditional building issues[7].

ver #2:
 - Rolled in a fix to the second patch to include certs/common.h in
   certs/common.c[6].

ver #1:
 - 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 thefile and to add kerneldoc comments.
