sys/kern : subr_hibernate.c
Log message:
Make writes of the hibernate signature go through the I/O page of the
piglet. This fixes a potential issue on arm64 where the kernel might
have been loaded into memory that isn't DMA reachable. It will also
help with implementing some future changes to make the side-effect free
I/O functions support hardware without cache-coherent DMA or IOMMUs.
