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

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

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

532 The kernel memory allocator divides physically contiguous memory

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