words, every architecture is now auto-sizing the kmem arena. This revision changes kmeminit() so that the definition of VM_KMEM_SIZE_SCALE becomes mandatory and the definition of VM_KMEM_SIZE becomes optional. Replace or eliminate all existing definitions of VM_KMEM_SIZE. With auto-sizing enabled, VM_KMEM_SIZE effectively became an alternate spelling for VM_KMEM_SIZE_MIN on most architectures. Use VM_KMEM_SIZE_MIN for clarity. Change kmeminit() so that the effect of defining VM_KMEM_SIZE is similar to that of setting the tunable vm.kmem_size. Whereas the macros VM_KMEM_SIZE_{MAX,MIN,SCALE} have had the same effect as the tunables vm.kmem_size_{max,min,scale}, the effects of VM_KMEM_SIZE and vm.kmem_size have been distinct. In particular, whereas VM_KMEM_SIZE was overridden by VM_KMEM_SIZE_{MAX,MIN,SCALE} and vm.kmem_size_{max,min,scale}, vm.kmem_size was not. Remedy this inconsistency. Now, VM_KMEM_SIZE can be used to set the size of the kmem arena at compile-time without that value being overridden by auto-sizing. Update the nearby comments to reflect the kmem submap being replaced by the kmem arena. Stop duplicating the auto-sizing formula in every machine- dependent vmparam.h and place it in kmeminit() where auto-sizing takes place.
