If linux,sml-log is available use it to get the TPM log rather than the
pointer found in linux,sml-base. This resolves an issue on PowerVM and KVM
on Power where after a kexec the memory pointed to by linux,sml-base may
have been corrupted. Also, linux,sml-log has replaced linux,sml-base and
linux,sml-size on these two platforms.

So shouldn't this have a fixed tag, or not?

In English: do we want this to be backported to stable kernel releases or not?

Ideally, yes. v3 will have 3 patches and all 3 of them will have to be 
backported *together* and not applied otherwise if any one of them 
fails. Can this be 'guaranteed'?

All of them will end up to stable if the following conditions hold:

- All have a fixes tag.
- All have "Cc: stable@vger.kernel.org".
- We agree in the review process that they are all legit fixes.
