Enable this if you want to support 64bit kernel on PA-RISC platform.

At the moment, only people willing to use more than 2GB of RAM,
or having a 64bit-only capable PA-RISC machine should say Y here.
enable this option otherwise. The 64bit kernel is significantly bigger
and slower than the 32bit one.

- help
- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). This is accomplished
- by pressing various keys while holding SysRq (Alt+PrintScreen). It
- also works on a serial console (on PC hardware at least), if you
- send a BREAK and then within 5 seconds a command keypress. The
- keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
- unless you really know what this hack does.

- Say Y here and build SMP to catch missing spinlock initialization
- and certain other kinds of spinlock errors commonly made. This is

- deadlocks are also debuggable.

- If you say Y here then read-write lock processing will count how many

- hacker asks for this option then say Y. Otherwise say N.

- If you say Y here the resulting kernel image will be slightly larger

- to solve problems without frame pointers.

- depends on DEBUG_KERNEL
- help
- If you say Y here the resulting kernel image will include
- debugging info resulting in a larger kernel image.

- If you don't debug the kernel, you can say N.
