[SPARC64]: Make use of Niagara 256MB PTEs for kernel mappings. We use a bitmap, one bit for every 256MB of memory. If the bit is set we can use a 256MB PTE for linear mappings, else we have to use a 4MB PTE. SUN4V support is there, and we can very easily add support for Panther cpu 256MB PTEs in the future.
