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

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

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

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

968 in the RMA (real memory area) at any 16k-aligned base address.
