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

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

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

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

606 the process as file descriptors supporting the read/write
607 syscalls, it's possible to isolate those applications in
608 their own address space using seccomp. Once seccomp is
