Pull keyring updates from David Howells:
 "Here's a set of minor keyrings fixes/cleanups that I've collected from
  various people for the upcoming merge window.

  A couple of them might, in theory, be visible to userspace:

   - Make blacklist_vet_description() reject uppercase letters as they
     don't match the all-lowercase hex string generated for a blacklist
     search.

     This may want reconsideration in the future, but, currently, you
     can't add to the blacklist keyring from userspace and the only
     source of blacklist keys generates lowercase descriptions.

   - Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that
     it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP
     into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.

     This isn't currently a problem as the blacklist keyring isn't
     currently writable by userspace.

  The rest of the patches are cleanups and I don't think they should
  have any visible effect"
