Two stable kernels — and maybe a third

[Posted February 14, 2023 by corbet]

The 6.1.12 and 5.15.94 stable kernel updates have been released, each with the usual set of important fixes. There is also a 5.10.168 release in the works, but it ran into some snags in the review process; it can be expected shortly.

Another set of updates, containing the mitigations for the just-disclosed cross-thread return-address prediction vulnerability (yet another Spectre variant that affects AMD processors), can be expected soon.

commit 6f0f2d5ef895d66a3f2b32dd05189ec34afa5a55 upstream.

Looks like the AMD mitigations were included in 6.1.12, so should not need an additional update.
