kernel - Increase KVM from 128G to 511G, further increase maximum swap
* Increase KVM (Kernel Virtual Memory) to the maximum we currently
support. Up to half of it can be used for swblock structures
(SWAPMETA in vmstat -z). This allows the following swap maximums.
128G of ram - 15TB of data can be swapped out.
256G of ram - 30TB of data can be swapped out.
512G+ of ram - 55TB - this is the maximum we can support swapped out.
* We can support > 512G of KVM in the future with only a bit of work on
how KVM is reserved.
* Remove some debugging code.
