commit 6d9ac5e4d70eba3e336f9809ba91ab2c49de6d87 upstream.

Potentially include errata for Landlock ABI v5 (Linux 6.10) and v6
(Linux 6.12).  That will be useful for the following signal scoping
erratum.

As explained in errata.h, this commit should be backportable without
conflict down to ABI v5.  It must then not include the errata/abi-6.h
file.

  * For each new erratum, we need to include all the ABI files up to the impacted
  * ABI to make all potential future intermediate errata easy to backport.
