My kernel build started failing recently with the following error. I use
a custom kernel config but looking at NOTES, it's not clear that I've
missed an option that would make it compile.

I've also tried compiling after blowing away usr/obj.
Ian
memmove is declared in systm.h, but I don't see include statement for systm.h in
nvme.h. Could you try including <sys/systm.h> in sys/dev/nvme/nvme.h and build
again?
It builds with that, but coincidentally GENERIC builds without that change.
Ian
Could you send your kernel config? Maybe sys/systm.h is included under GENERIC
but not under some configs.
