+	  Xtensa processors are 32-bit RISC machines designed by Tensilica
+	  primarily for embedded systems.  These processors are both
+	  configurable and extensible.  The Linux port to the Xtensa
+	  architecture supports all processor configurations and extensions,
+	  with reasonable minimum requirements.  The Xtensa Linux project has
+	  a home page at <http://xtensa.sourceforge.net/>.

+
+	   Say Y here to enable unaligned memory access in user space.

+	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.
+           Unfortunately the kernel code has some race conditions if both
+           CONFIG_SMP and CONFIG_PREEMPT are enabled, so this option is
+           currently disabled if you are building an SMP kernel.
+
+           Say Y here if you are building a kernel for a desktop, embedded
+           or real-time system.  Say N if you are unsure.

+	  architectures, you should supply some command-line options at build

+config HOTPLUG
+
+	bool "Support for hot-pluggable devices"
+	---help---
+	Say Y here if you want to plug devices into your computer while
+	the system is running, and be able to use them quickly.  In many
+	cases, the devices can likewise be unplugged at any time too.
+
+	One well known example of this is PCMCIA- or PC-cards, credit-card
+	size devices such as network cards, modems or hard drives which are
+	plugged into slots found on all modern laptop computers.  Another
+	example, used on modern desktops as well as laptops, is USB.
+
+	Enable HOTPLUG and KMOD, and build a modular kernel.  Get agent
+	software (at <http://linux-hotplug.sourceforge.net/>) and install it.
+	Then your kernel will automatically call out to a user mode "policy
+	agent" (/sbin/hotplug) to load modules and set up software needed
+	to use devices as you hotplug them.

+
+          This is especially useful if you have compiled the kernel with the

+	  for examining kernel data structures on the live kernel.
