+ If you say Y here, you will enable support for using the 'cycles'

+ still be able to read it (such as for performance monitoring), but
+ writing the registers will most likely crash the kernel.

- This option allows you to set the load address of the kernel.
- This can be useful if you are on a board which has a small amount
- of memory or you wish to reserve some memory at the beginning of

- Note that you need to keep this value above 4k (0x1000) as this

- * Xen event channels

- * Xen models interrupts with abstract event channels. Because each
- * domain gets 1024 event channels, but NR_IRQ is not that large, we
- * must dynamically map irqs<->event channels. The event channels
- * interface with the rest of the kernel by defining a xen interrupt
- * chip. When an event is recieved, it is mapped to an irq and sent
- * through the normal interrupt processing path.
- *
- * There are four kinds of events which can be mapped to an event
- * channel:
- *
- * 1. Inter-domain notifications. This includes all the virtual
- * device events, since they're driven by front-ends in another domain
- * (typically dom0).
- * 2. VIRQs, typically used for timers. These are per-cpu events.
- * 3. IPIs.
- * 4. Hardware interrupts. Not supported at present.
