Thanks.

We're all horridly busy with bugfixes at present and the first thing
recipients think when presented with yet another is "why should I look
at this".

So it really helps to start out with a succinct and punchy sentence
which explains that thing.

LLM suggested to me

: KFENCE initialization failures can cause kernel crashes or memory
: corruption, while a RISC-V failure can prevent the system from booting.
: These fixes make the failure paths safe and allow systems to continue
: running with KFENCE disabled.

How does that sound?
