Message:

Split frame_arch_init() into two parts.

• frame_low_arch_init() is meant to initialize physical memory that will be accessible using the kernel identity mapping
• frame_high_arch_init() is meant to initialize physical memory beyond the reach of the kernel identity mapping; zones in the high memory should have configuration frames allocated externally from the low memory (which will be allowed)
