Subject: [RFC PATCH 0/4] Alternative TPM patches for Trenchboot

This is my alternative patch set to the TPM patches included into
Trenchboot series v11. I don't mind to which tree these are
picked in the end. All the patches also have my sob's, so in that
sense things are also cleared up.

At least slmodule needs to be patched in the series given that
tpm_chip_set_locality() returns zero on success.

It is not really my problem but I'm also wondering how the
initialization order is managed. What if e.g. IMA happens to
initialize before slmodule?
