Dear Maintainer,

due to an off-by-one bug in the L1TF patch, the "rare" case of systems still vulnerable
is more frequent.

Originally this was reported in OpenSUSE, but I can confirm this is also true
with the latest Debian kernel.

Please cherry-pick the following upstream patch to resolve this issue:

Best regards,
Markus
