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

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

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

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

856 Please refer to the init code for finding the TLB page size.
858 DYNAMIC_MEMSTART is an easy way of implementing pseudo-RELOCATABLE

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