Kernel 5.16

[Diego Garcia]

Kernel-5.16 is out.

Easy build, as usual. Total build time: 2:15 (2 minutes, 15 seconds)

Using "make oldconfig" there is a new build option that I don't fully understand:

Enforce strict size checking for sigaltstack

This relates to the FPU and register saves during signal entry. The default setting
is "NO" but on AVX-512 machines (e.g. Xeon) could it be better to enable this option?

It also seems that if enabled then other programs (glibc and others) would have
to be rebuilt:

More challenges from the Linux universe. One has to love it.
