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

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

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

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

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

966 This builds a kernel image that is capable of running anywhere
967 in the RMA (real memory area) at any 16k-aligned base address.
968 The kernel is linked as a position-independent executable (PIE)
969 and contains dynamic relocations which are processed early
970 in the bootup process.
972 One use is for the kexec on panic case where the recovery kernel
973 must live at a different physical address than the primary
