MFC r257854 (discussed with alc@)
As of r257209, all architectures have defined VM_KMEM_SIZE_SCALE. In other 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.

Add some extra sanity checking and checks to printf format specifiers.
Try even harder to find a console before giving up.
Make devices with registers into the KVA region work reliably.
Turn on VM_KMEM_SIZE_SCALE on 32-bit as well as 64-bit PowerPC.
Return NOKEY instead of 0 if there are no more key presses queued.

Add pmap_mapdev_attr() and pmap_kenter_attr() interfaces.
Fix concurrency issues with TLB1 updates and make pmap_kextract() search TLB1 mappings as well
Interrelated improvements to early boot mappings: - Remove explicit requirement that the SOC registers be found except as an optimization (although the MPC85XX LAW drivers still require they be found externally, which should change). - Remove magic CCSRBAR_VA value. - Allow bus_machdep.c's early-boot code to handle non 1:1 mappings and systems not in real-mode or global 1:1 maps in early boot. - Allow pmap_mapdev() on Book-E to reissue previous addresses if the area is already mapped. Additionally have it check all mappings, not just the CCSR area.
Add some extra sanity checking and checks to printf format specifiers.
Bump initial TLB size. The kernel is not necessarily less than 16 MB
Handle (in a slightly ugly way) ePAPR-type loaders that just place a device tree into r3.
