- 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.

+ This enables support for systems with more than one CPU. If you have
+ a system with only one CPU, like most personal computers, say N. If
+ you have a system with more than one CPU, say Y.
+
+ If you say N here, the kernel will run on single and multiprocessor
+ machines, but will use only one CPU of a multiprocessor machine. If
+ you say Y here, the kernel will run on many, but not all,
+ singleprocessor machines. On a singleprocessor machine, the kernel
+ will run faster if you say N here.

+ See also <file:Documentation/i386/IO-APIC.txt>,
+ <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available at
+ <http://www.tldp.org/docs.html#howto>.
- Say Y here if you are building a kernel for a desktop, embedded
- or real-time system. Say N if you are unsure.
+ If you don't know what to do here, say N.

tracked, even when system is powered down. This is available on-chip
on the MN103E010.
