-config DEBUG_STACKOVERFLOW

-	  This option will cause messages to be printed if free stack space
-	  drops below a certain limit.
-
-config KPROBES
-	bool "Kprobes"
-	depends on DEBUG_KERNEL
-	help
-	  Kprobes allows you to trap at almost any kernel address and
-	  execute a callback function.  register_kprobe() establishes
-	  a probepoint and specifies the callback.  Kprobes is useful
-	  for kernel debugging, non-intrusive instrumentation and testing.
-	  If in doubt, say "N".
-
-config DEBUG_STACK_USAGE
-	bool "Stack utilization instrumentation"
-	depends on DEBUG_KERNEL
-	help
-	  Enables the display of the minimum amount of free stack which each
-	  task has ever had available in the sysrq-T and sysrq-P debug output.
-
-	  This option will slow down process creation somewhat.
-
-config DEBUGGER
-	bool "Enable debugger hooks"
-	depends on DEBUG_KERNEL
-	help
-	  Include in-kernel hooks for kernel debuggers. Unless you are
-	  intending to debug the kernel, say N here.
-
-config XMON
-	bool "Include xmon kernel debugger"
-	depends on DEBUGGER && !PPC_ISERIES
-	help
-	  Include in-kernel hooks for the xmon kernel monitor/debugger.
-	  Unless you are intending to debug the kernel, say N here.
-	  Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise
-	  nothing will appear on the screen (xmon writes directly to the
-	  framebuffer memory).
-	  The cmdline option 'xmon' or 'xmon=early' will drop into xmon very
-	  early during boot. 'xmon=on' will just enable the xmon debugger hooks.
-	  'xmon=off' will disable the debugger hooks if CONFIG_XMON_DEFAULT is set.
-
-config XMON_DEFAULT
-	bool "Enable xmon by default"
-	depends on XMON
-	help
-	  xmon is normally disabled unless booted with 'xmon=on'.
-	  Use 'xmon=off' to disable xmon init during runtime.
-
-config IRQSTACKS
-	bool "Use separate kernel stacks when processing interrupts"
-	help
-	  If you say Y here the kernel will use separate kernel stacks
-	  for handling hard and soft interrupts.  This can help avoid
-	  overflowing the process kernel stacks.

+/*************************************************************************
+*  CPUSaver parameters
+*
+*  All CPUSaver parameters are 16-bit literals that are part of a
+*  "move immediate value" instruction.  By changing the value of
+*  the literal in the instruction before the code is loaded, the
+*  driver can change the algorithm.
+*
+*  INTDELAY - This loads the dead-man timer with its inital value.
+*    When this timer expires the interrupt is asserted, and the 
+*    timer is reset each time a new packet is received.  (see
+*    BUNDLEMAX below to set the limit on number of chained packets)
+*    The current default is 0x600 or 1536.  Experiments show that
+*    the value should probably stay within the 0x200 - 0x1000.
+*
+*  BUNDLEMAX - 
+*    This sets the maximum number of frames that will be bundled.  In
+*    some situations, such as the TCP windowing algorithm, it may be
+*    better to limit the growth of the bundle size than let it go as
+*    high as it can, because that could cause too much added latency.
+*    The default is six, because this is the number of packets in the
+*    default TCP window size.  A value of 1 would make CPUSaver indicate
+*    an interrupt for every frame received.  If you do not want to put
+*    a limit on the bundle size, set this value to xFFFF.
+*
+*  BUNDLESMALL - 
+*    This contains a bit-mask describing the minimum size frame that
+*    will be bundled.  The default masks the lower 7 bits, which means
+*    that any frame less than 128 bytes in length will not be bundled,
+*    but will instead immediately generate an interrupt.  This does
+*    not affect the current bundle in any way.  Any frame that is 128
+*    bytes or large will be bundled normally.  This feature is meant
+*    to provide immediate indication of ACK frames in a TCP environment.
+*    Customers were seeing poor performance when a machine with CPUSaver
+*    enabled was sending but not receiving.  The delay introduced when
+*    the ACKs were received was enough to reduce total throughput, because
+*    the sender would sit idle until the ACK was finally seen.
+*
+*    The current default is 0xFF80, which masks out the lower 7 bits.
+*    This means that any frame which is x7F (127) bytes or smaller
+*    will cause an immediate interrupt.  Because this value must be a 
+*    bit mask, there are only a few valid values that can be used.  To
+*    turn this feature off, the driver can write the value xFFFF to the
+*    lower word of this instruction (in the same way that the other
+*    parameters are used).  Likewise, a value of 0xF800 (2047) would
+*    cause an interrupt to be generated for every frame, because all
+*    standard Ethernet frames are <= 2047 bytes in length.
