351 kexec is a system call that implements the ability to shutdown your

353 but it is independent of the system firmware. And like a reboot
354 you can start any kernel with it, not just Linux.
356 The name comes from the similarity to the exec system call.
358 It is an ongoing process to be certain the hardware in a machine
359 is properly shutdown, so do not be surprised if this code does not
360 initially work for you. It may help to enable device hotplugging

458 Note, that kernel will be able to run only those applications,
459 which had been compiled using binutils later than 2.17.50.0.3 with
460 '-zmax-page-size' set to 256K (the default is 64K). Or, if using
461 the older binutils, you can patch them with a trivial patch, which
462 changes the ELF_MAXPAGESIZE definition from 0x10000 to 0x40000.
468 Select the kernel logical page size. Increasing the page size
469 will reduce software overhead at each page boundary, allow
470 hardware prefetch mechanisms to be more effective, and allow
471 larger dma transfers increasing IO efficiency and reducing
472 overhead. However the utilization of memory will increase.
473 For example, each cached file will using a multiple of the
474 page size to hold its contents and the difference between the
475 end of file and the end of page is wasted.
477 Some dedicated systems, such as software raid serving with
478 accelerated calculations, have shown significant increases.
480 If you configure a 64 bit kernel for 64k pages but the
481 processor does not support them, then the kernel will simulate
482 them with 4k pages, loading them on demand, but with the
483 reduced software overhead and larger internal fragmentation.

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

532 keeps in the memory allocator. If you need to allocate very large
533 blocks of physically contiguous memory, then you may need to
536 This config option is actually maximum order plus one. For example,
537 a value of 11 means that the largest free memory block is 2^10 pages.
539 The page size is not necessarily 4KB. For example, on 64-bit
540 systems, 64KB pages can be enabled via CONFIG_PPC_64K_PAGES. Keep
