. make vm tell kernel virtual locations of mappings . makes _minix_kerninfo feature work . fix for mappings being larger than what 1 pde can address (e.g. devices memory requested on arm) . still requires a special case for devices memory for the kernel, which has to switch to virtual addressing Change-Id: I2e94090aa432346fa4da0edeba72f0b7406c2ad7
