This adds the Kernel Electric-Fence (KFENCE) infrastructure. KFENCE is a
low-overhead sampling-based memory safety error detector of heap

series enables KFENCE for the x86 and arm64 architectures, and adds
KFENCE hooks to the SLAB and SLUB allocators.

I think this is getting close to a good state, just a couple minor issues left.

Now that the magic "embed the memory pool in the BSS section" stuff is
gone, this series looks fairly straightforward.
