308	help
309	  kexec is a system call that implements the ability to shutdown your
310	  current kernel, and to start another kernel.  It is like a reboot
311	  but it is independent of the system firmware.   And like a reboot
312	  you can start any kernel with it, not just Linux.
313
314	  The name comes from the similarity to the exec system call.
315
316	  It is an ongoing process to be certain the hardware in a machine
317	  is properly shutdown, so do not be surprised if this code does not
318	  initially work for you.  It may help to enable device hotplugging
319	  support.  As of this writing the exact hardware interface is
320	  strongly in flux, so no good recommendation can be made.

409	help
410	  This option changes the kernel logical page size to 64k. On machines
411	  without processor support for 64k pages, the kernel will simulate
412	  them by loading each individual 4k page on demand transparently,

421	help
422	  The kernel memory allocator divides physically contiguous memory
423	  blocks into "zones", where each zone is a power of two number of
424	  pages.  This option selects the largest power of two that the kernel
425	  keeps in the memory allocator.  If you need to allocate very large
426	  blocks of physically contiguous memory, then you may need to
427	  increase this value.
428
429	  This config option is actually maximum order plus one. For example,
430	  a value of 11 means that the largest free memory block is 2^10 pages.
431
432	  The page size is not necessarily 4KB.  For example, on 64-bit
433	  systems, 64KB pages can be enabled via CONFIG_PPC_64K_PAGES.  Keep
434	  this in mind when choosing a value for this option.

446	depends on PPC64 && SMP
447	help
448	  SMT scheduler support improves the CPU scheduler's decision making

468	  On some platforms, there is currently no way for the boot loader to
469	  pass arguments to the kernel. For these platforms, you can supply
470	  some command-line options at build time by entering them here.  In

499	  This kernel feature is useful for number crunching applications

502	  the process as file descriptors supporting the read/write

666	help
667	  This option will enable prompting for a variety of advanced kernel
668	  configuration options.  These options can cause the kernel to not
669	  work if they are set incorrectly, but can be used to optimize certain
670	  aspects of kernel memory management.

681	  This option allows you to set the maximum amount of memory which
682	  will be used as "low memory", that is, memory which the kernel can
683	  access directly, without having to set up a kernel virtual mapping.
684	  This can be useful in optimizing the layout of kernel virtual
685	  memory.

697	  This builds a kernel image that is capable of running at the
698	  location the kernel is loaded at (some alignment restrictions may
699	  exist).
700
701	  One use is for the kexec on panic case where the recovery kernel
702	  must live at a different physical address than the primary
703	  kernel.
704
705	  Note: If CONFIG_RELOCATABLE=y, then the kernel runs from the address
706	  it has been loaded at and the compile time physical addresses
707	  CONFIG_PHYSICAL_START is ignored.  However CONFIG_PHYSICAL_START
708	  setting can still be useful to bootwrappers that need to know the
709	  load location of the kernel (eg. u-boot/mkimage).
