+config PPC_DISABLE_WERROR
+	bool "Don't build arch/powerpc code with -Werror"
+	help
+	  This option tells the compiler NOT to build the code under
+	  arch/powerpc with the -Werror flag (which means warnings
+	  are treated as errors).
+
+	  Only enable this if you are hitting a build failure in the
+	  arch/powerpc code caused by a warning, and you don't feel
+	  inclined to fix it.
+
+config PPC_WERROR
+	bool
+	depends on !PPC_DISABLE_WERROR
+	default y
+
+config PRINT_STACK_DEPTH
+	int "Stack depth to print" if DEBUG_KERNEL
+	default 64
+	help
+	  This option allows you to set the stack depth that the kernel
+	  prints in stack traces. This can be useful if your display is
+	  too small and stack traces cause important information to
+	  scroll off the screen.
+
+config HCALL_STATS
+	bool "Hypervisor call instrumentation"
+	depends on PPC_PSERIES && DEBUG_FS && TRACEPOINTS
+	help
+	  Adds code to keep track of the number of hypervisor calls made and
+	  the amount of time spent in hypervisor calls.  Wall time spent in
+	  each call is always calculated, and if available CPU cycles spent
+	  are also calculated.  A directory named hcall_inst is added at the
+	  root of the debugfs filesystem.  Within the hcall_inst directory
+	  are files that contain CPU specific call statistics.
+
+	  This option will add a small amount of overhead to all hypervisor
+	  calls.
+
+config PPC_EMULATED_STATS
+	bool "Emulated instructions tracking"
+	depends on DEBUG_FS
+	help
+	  Adds code to keep track of the number of instructions that are
+	  emulated by the in-kernel emulator. Counters for the various classes
+	  of emulated instructions are available under
+	  powerpc/emulated_instructions/ in the root of the debugfs file
+	  system. Optionally (controlled by
+	  powerpc/emulated_instructions/do_warn in debugfs), rate-limited
+	  warnings can be printed to the console when instructions are
+	  emulated.
+
+config CODE_PATCHING_SELFTEST
+	bool "Run self-tests of the code-patching code"
+	depends on DEBUG_KERNEL
+
+config JUMP_LABEL_FEATURE_CHECKS
+	bool "Enable use of jump label for cpu/mmu_has_feature()"
+	depends on JUMP_LABEL
+	default y
+	help
+	  Selecting this options enables use of jump labels for some internal
+	  feature checks. This should generate more optimal code for those
+	  checks.
+
+config JUMP_LABEL_FEATURE_CHECK_DEBUG
+	bool "Do extra check on feature fixup calls"
+	depends on DEBUG_KERNEL && JUMP_LABEL_FEATURE_CHECKS
+	help
+	  This tries to catch incorrect usage of cpu_has_feature() and
+	  mmu_has_feature() in the code.
+
+	  If you don't know what this means, say N.

+config XMON
+	bool "Include xmon kernel debugger"
+	depends on DEBUG_KERNEL
+	select CONSOLE_POLL if SERIAL_CPM_CONSOLE
+	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.
+	  xmon will print a backtrace on the very first invocation.
+	  'xmon=nobt' will disable this autobacktrace.
+
+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 XMON_DISASSEMBLY
+	bool "Include disassembly support in xmon"
+	depends on XMON
+	default y
+	help
+	  Include support for disassembling in xmon. You probably want
+	  to say Y here, unless you're building for a memory-constrained
+	  system.
+
+config XMON_DEFAULT_RO_MODE
+	bool "Restrict xmon to read-only operations by default"
+	depends on XMON
+	default y
+	help
+	  Operate xmon in read-only mode. The cmdline options 'xmon=rw' and
+	  'xmon=ro' override this default.

+	default y
+
+config BDI_SWITCH
+	bool "Include BDI-2000 user context switcher"
+	depends on DEBUG_KERNEL && PPC32
+	help
+	  Include in-kernel support for the Abatron BDI2000 debugger.
+	  Unless you are intending to debug the kernel with one of these
+	  machines, say N here.
+
+config BOOTX_TEXT
+	bool "Support for early boot text console (BootX or OpenFirmware only)"
+	depends on PPC_BOOK3S
+	help
+	  Say Y here to see progress messages from the boot firmware in text
+	  mode. Requires either BootX or Open Firmware.
+
+config PPC_EARLY_DEBUG
+	bool "Early debugging (dangerous)"
+	help
+	  Say Y to enable some early debugging facilities that may be available
+	  for your processor/board combination. Those facilities are hacks
+	  intended to debug problems early during boot, this should not be
+	  enabled in a production kernel.
+	  Note that enabling this will also cause the kernel default log level
+	  to be pushed to max automatically very early during boot
+
+choice
+	prompt "Early debugging console"
+	depends on PPC_EARLY_DEBUG
+	help
+	  Use the selected console for early debugging. Careful, if you

+
+config PPC_EARLY_DEBUG_LPAR_HVSI

+config PPC_EARLY_DEBUG_44x
+	bool "Early serial debugging for IBM/AMCC 44x CPUs"
+	depends on 44x
+	help
+	  Select this to enable early debugging for IBM 44x chips via the
+	  inbuilt serial port.  If you enable this, ensure you set
+	  PPC_EARLY_DEBUG_44x_PHYSLOW below to suit your target board.
+
+config PPC_EARLY_DEBUG_40x
+	bool "Early serial debugging for IBM/AMCC 40x CPUs"
+	depends on 40x
+	help
+	  Select this to enable early debugging for IBM 40x chips via the
+	  inbuilt serial port. This works on chips with a 16550 compatible
+	  UART.
+
+config PPC_EARLY_DEBUG_CPM
+	bool "Early serial debugging for Freescale CPM-based serial ports"
+	depends on SERIAL_CPM=y
+	help
+	  Select this to enable early debugging for Freescale chips
+	  using a CPM-based serial port.  This assumes that the bootwrapper
+	  has run, and set up the CPM in a particular way.

+	  Select this to enable early debugging for the PowerNV platform
+	  using an "hvsi" console
+
+config PPC_EARLY_DEBUG_MEMCONS
+	bool "In memory console"
+	help
+	  Select this to enable early debugging using an in memory console.
+	  This console provides input and output buffers stored within the
+	  kernel BSS and should be safe to select on any system. A debugger
+	  can then be used to read kernel output or send input to the console.
+
+config PPC_EARLY_DEBUG_16550
+	bool "Serial 16550"

+	  the machine built-in serial ports.
