An update on the previous RFC patchset found here:

https://lore.kernel.org/linux-security-module/161377712068.87807.12246856567527156637.stgit@sifl/

Aside from being rebased to the current SELinux next branch (which
in turn is based on v5.12-rc2), this revision changes the binder
related code to always use the objective credentials as discussed
in the thread above.  I've also dropped the AppArmor patch as John
has a better version in progress; in the meantime AppArmor should
continue to work exactly as it did before this patchset so there
is no harm in merging this without the AppArmor patch.

Casey, John, and Richard; I dropped your ACKs, Reviewed-by, etc.
tags as the binder changes seemed substantial enough to not
carryover your tags.  I would appreciate it if you could re-review
this revision; the changes should be minimal.  I did leave Mimi's
tag on this revision as she qualified it for IMA and that code
didn't change.
