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

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

535 The kernel memory allocator divides physically contiguous memory

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

606 syscalls, it's possible to isolate those applications in
607 their own address space using seccomp. Once seccomp is
