  	  This selects the system type of your hardware.  A "generic" kernel

  	  Build a kernel that runs on HP zx1 and sx1000 systems even when they
  	  have broken PCI devices which cannot DMA to full 32 bits.  Apart
  	  from support for the HP I/O MMU, this includes support for the software
  	  I/O TLB, which allows supporting the broken devices at the expense of

  	  This enables support for systems with more than one CPU. If you have

  	  than one CPU, say Y.
  
  	  If you say N here, the kernel will run on single and multiprocessor
  	  systems, but will use only one CPU of a multiprocessor system.  If
  	  you say Y here, the kernel will run on many, but not all,
  	  single processor systems.  On a single processor system, the kernel
  	  will run faster if you say N here.
  
  	  See also the <file:Documentation/smp.txt> and the SMP-HOWTO

  	  You should set this to the number of CPUs in your system, but
  	  keep in mind that a kernel compiled for, e.g., 2 CPUs will boot but
  	  only use 2 CPUs on a >2 CPU system.  Setting this to a value larger

  	Say Y if you need to force the assumption that CPEI can be re-targetted to
  	any cpu in the system. This hint is available via ACPI 3.0 specifications.
  	Tiger4 systems are capable of re-directing CPEI to any CPU other than BSP.
  	This option it useful to enable this feature on older BIOS's as well.
  	You can also enable this by using boot command line option force_cpei=1.

  config PREEMPT
  	bool "Preemptible Kernel"
          help
            This option reduces the latency of the kernel when reacting to
            real-time or interactive events by allowing a low priority process to
            be preempted even if it is in kernel mode executing a system call.
            This allows applications to run more reliably even when the system is
            under load.
  
            Say Y here if you are building a kernel for a desktop, embedded
            or real-time system.  Say N if you are unsure.

  	help
  	  Selects whether support for the IA-64 performance monitor hardware
  	  is included in the kernel.  This makes some kernel data-structures a

  config IA64_PALINFO

  	help
  	  If you say Y here, you are able to get PAL (Processor Abstraction
  	  Layer) information in /proc/pal.  This contains useful information
  	  about the processors in your systems, such as cache and TLB sizes
  	  and the PAL firmware version in use.
  
  	  To use this option, you have to ensure that the "/proc file system
  	  support" (CONFIG_PROC_FS) is enabled, too.

  	help
  	  kexec is a system call that implements the ability to shutdown your
  	  current kernel, and to start another kernel.  It is like a reboot
  	  but it is indepedent of the system firmware.   And like a reboot
  	  you can start any kernel with it, not just Linux.
  
  	  The name comes from the similiarity to the exec system call.
  
  	  It is an ongoing process to be certain the hardware in a machine
  	  is properly shutdown, so do not be surprised if this code does not
  	  initially work for you.  It may help to enable device hotplugging
  	  support.  As of this writing the exact hardware interface is
