Thanks and well done to the Gentoo Kernel Project for promptly pushing
out 5.15.122, 6.1.41, et alia. Those latest kernels add mitigation for
the "Zenbleed" vulnerability found in AMD Ryzen and Epyc processors.

I noticed that my Ubunutu server machines got a kernel update this
morning also, and I assumed that update also contained the Zenbleed
mitigation -- but it did not. Ubuntu apparently has not pushed out
kernel updates for that yet. [My Ubuntu machines are unaffected, but
I'd be a little worried if they were.]
