- * The kdump dump kernel is one example where KERNELBASE != PAGE_OFFSET.

- * PAGE_OFFSET is the virtual address of the start of lowmem.

- * PHYSICAL_START is the physical address of the start of the kernel.
- *
- * MEMORY_START is the physical address of the start of lowmem.
- *
- * KERNELBASE, PAGE_OFFSET, and PHYSICAL_START are all configurable on
- * ppc32 and based on how they are set we determine MEMORY_START.
- *
- * For the linear mapping the following equation should be true:
- * KERNELBASE - PAGE_OFFSET = PHYSICAL_START - MEMORY_START
- *
- * Also, KERNELBASE >= PAGE_OFFSET and PHYSICAL_START >= MEMORY_START
- *
- * There are two was to determine a physical address from a virtual one:
- * va = pa + PAGE_OFFSET - MEMORY_START
- * va = pa + KERNELBASE - PHYSICAL_START
- *
- * If you want to know something's offset from the start of the kernel you
- * should subtract KERNELBASE.
- *
- * If you want to test if something's a kernel address, use is_kernel_addr().
