356 kexec is a system call that implements the ability to shutdown your
357 current kernel, and to start another kernel. It is like a reboot
358 but it is independent of the system firmware. And like a reboot
359 you can start any kernel with it, not just Linux.
361 The name comes from the similarity to the exec system call.
363 It is an ongoing process to be certain the hardware in a machine
364 is properly shutdown, so do not be surprised if this code does not
365 initially work for you. It may help to enable device hotplugging

462 Turning this option off allows you to select 256KB PAGE_SIZE on 44x.
463 Note, that kernel will be able to run only those applications,
464 which had been compiled using binutils later than 2.17.50.0.3 with
465 '-zmax-page-size' set to 256K (the default is 64K). Or, if using
466 the older binutils, you can patch them with a trivial patch, which
467 changes the ELF_MAXPAGESIZE definition from 0x10000 to 0x40000.
473 Select the kernel logical page size. Increasing the page size
474 will reduce software overhead at each page boundary, allow
475 hardware prefetch mechanisms to be more effective, and allow
476 larger dma transfers increasing IO efficiency and reducing
477 overhead. However the utilization of memory will increase.
478 For example, each cached file will using a multiple of the
479 page size to hold its contents and the difference between the
480 end of file and the end of page is wasted.
482 Some dedicated systems, such as software raid serving with
483 accelerated calculations, have shown significant increases.
485 If you configure a 64 bit kernel for 64k pages but the
486 processor does not support them, then the kernel will simulate
487 them with 4k pages, loading them on demand, but with the
488 reduced software overhead and larger internal fragmentation.
489 For the 32 bit kernel, a large page option will not be offered

534 The kernel memory allocator divides physically contiguous memory
535 blocks into "zones", where each zone is a power of two number of

537 keeps in the memory allocator. If you need to allocate very large
538 blocks of physically contiguous memory, then you may need to
541 This config option is actually maximum order plus one. For example,
542 a value of 11 means that the largest free memory block is 2^10 pages.
544 The page size is not necessarily 4KB. For example, on 64-bit
