	  but it is independent of the system firmware.   And like a reboot
	  you can start any kernel with it, not just Linux.

	  The name comes from the similarity to the exec system call.

	  It is an ongoing process to be certain the hardware in a machine
	  is properly shutdown, so do not be surprised if this code does not
	  initially work for you.  It may help to enable device hotplugging

choice
	prompt "Page size"
	default PPC_4K_PAGES
	help
	  Select the kernel logical page size. Increasing the page size
	  will reduce software overhead at each page boundary, allow
	  hardware prefetch mechanisms to be more effective, and allow
	  larger dma transfers increasing IO efficiency and reducing
	  overhead. However the utilization of memory will increase.
	  For example, each cached file will using a multiple of the
	  page size to hold its contents and the difference between the
	  end of file and the end of page is wasted.

	  Some dedicated systems, such as software raid serving with
	  accelerated calculations, have shown significant increases.

	  If you configure a 64 bit kernel for 64k pages but the
	  processor does not support them, then the kernel will simulate
	  them with 4k pages, loading them on demand, but with the
	  reduced software overhead and larger internal fragmentation.
	  For the 32 bit kernel, a large page option will not be offered
	  unless it is supported by the configured processor.

	  If unsure, choose 4K_PAGES.

	  sizes up to 64k, you will need to compile all of your user

	help
	  The kernel memory allocator divides physically contiguous memory
	  blocks into "zones", where each zone is a power of two number of
	  pages.  This option selects the largest power of two that the kernel
	  keeps in the memory allocator.  If you need to allocate very large
	  blocks of physically contiguous memory, then you may need to
	  increase this value.

	  This config option is actually maximum order plus one. For example,
	  a value of 11 means that the largest free memory block is 2^10 pages.

	  The page size is not necessarily 4KB.  For example, on 64-bit
	  systems, 64KB pages can be enabled via CONFIG_PPC_64K_PAGES.  Keep
	  this in mind when choosing a value for this option.

config PPC_SUBPAGE_PROT

	  This builds a kernel image that is capable of running anywhere
	  in the RMA (real memory area) at any 16k-aligned base address.
	  The kernel is linked as a position-independent executable (PIE)
	  and contains dynamic relocations which are processed early
	  in the bootup process.

	  One use is for the kexec on panic case where the recovery kernel
	  must live at a different physical address than the primary
	  kernel.
