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

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

537 The kernel memory allocator divides physically contiguous memory
538 blocks into "zones", where each zone is a power of two number of
539 pages. This option selects the largest power of two that the kernel
540 keeps in the memory allocator. If you need to allocate very large
541 blocks of physically contiguous memory, then you may need to
544 This config option is actually maximum order plus one. For example,
545 a value of 11 means that the largest free memory block is 2^10 pages.
547 The page size is not necessarily 4KB. For example, on 64-bit
548 systems, 64KB pages can be enabled via CONFIG_PPC_64K_PAGES. Keep

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

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