436           This code also only takes effect if a memory hole of greater than
437           1 Gb is found during boot.  You must turn this option on if you
438           require the DISCONTIGMEM option for your machine. If you are

469           Selects whether support for the IA-64 performance monitor hardware
470           is included in the kernel.  This makes some kernel data-structures a
471           little bigger and slows down execution a bit, but it is generally
472           a good idea to turn this on.  If you're unsure, say Y.

479           about the processors in your systems, such as cache and TLB sizes
480           and the PAL firmware version in use.
481 
482           To use this option, you have to ensure that the "/proc file system
483           support" (CONFIG_PROC_FS) is enabled, too.

489           will provide a sysfs interface for user applications to
490           call MC error injection PAL procedures to inject various errors.

512           handler if there is an HPQ5001 device or if the user supplies
513           the "force" module parameter, e.g., with the "aml_nfw.force"

523           kexec is a system call that implements the ability to shutdown your
524           current kernel, and to start another kernel.  It is like a reboot
525           but it is independent of the system firmware.   And like a reboot
526           you can start any kernel with it, not just Linux.
527 
528           The name comes from the similarity to the exec system call.
529 
530           It is an ongoing process to be certain the hardware in a machine
531           is properly shutdown, so do not be surprised if this code does not
532           initially work for you.  As of this writing the exact hardware
