-config MATH_EMULATION
-	bool
-	prompt "Math emulation" if X86_32
-	---help---
-	  Linux can emulate a math coprocessor (used for floating point

-	  a math coprocessor built in, 486SX and 386 do not, unless you added
-	  a 487DX or 387, respectively. (The messages during boot time can
-	  give you some hints here ["man dmesg"].) Everyone needs either a
-	  coprocessor or this emulation.
-
-	  If you don't have a math coprocessor, you need to say Y here; if you
-	  say Y here even though you have a coprocessor, the coprocessor will
-	  be used nevertheless. (This behavior can be changed with the kernel
-	  command line option "no387", which comes handy if your coprocessor
-	  is broken. Try "man bootparam" or see the documentation of your boot
-	  loader (lilo or loadlin) about how to pass options to the kernel at
-	  boot time.) This means that it is a good idea to say Y here if you
-	  intend to use this kernel on different machines.
-
-	  More information about the internals of the Linux math coprocessor
-	  emulation can be found in <file:arch/x86/math-emu/README>.

-config MTRR
-	bool "MTRR (Memory Type Range Register) support"
-	---help---
-	  On Intel P6 family processors (Pentium Pro, Pentium II and later)
-	  the Memory Type Range Registers (MTRRs) may be used to control
-	  processor access to memory ranges. This is most useful if you have
-	  a video (VGA) card on a PCI or AGP bus. Enabling write-combining
-	  allows bus write transfers to be combined into a larger transfer
-	  before bursting over the PCI/AGP bus. This can increase performance
-	  of image write operations 2.5 times or more. Saying Y here creates a
-	  /proc/mtrr file which may be used to manipulate your processor's
-	  MTRRs. Typically the X server should use this.
-
-	  This code has a reasonably generic interface so that similar
-	  control registers on other processors can be easily supported
-	  as well:
-
-	  The Cyrix 6x86, 6x86MX and M II processors have Address Range
-	  Registers (ARRs) which provide a similar functionality to MTRRs. For
-	  these, the ARRs are used to emulate the MTRRs.
-	  The AMD K6-2 (stepping 8 and above) and K6-3 processors have two
-	  MTRRs. The Centaur C6 (WinChip) has 8 MCRs, allowing
-	  write-combining. All of these processors are supported by this code
-	  and it makes sense to say Y here if you have one of them.
-
-	  Saying Y here also fixes a problem with buggy SMP BIOSes which only
-	  set the MTRRs for the boot CPU and not for the secondary CPUs. This
-	  can lead to all sorts of problems, so it's good to say Y here.
-
-	  You can safely say Y even if your machine doesn't have MTRRs, you'll
-	  just add about 9 KB to your kernel.

-
-	  It is an ongoing process to be certain the hardware in a machine
-	  is properly shutdown, so do not be surprised if this code does not

-	  This should be normally only set in special crash dump kernels

-	  a crash by kdump/kexec. The crash dump kernel must be compiled
-	  to a memory address not used by the main kernel or BIOS using
-	  PHYSICAL_START, or it must be built as a relocatable image
-	  (CONFIG_RELOCATABLE=y).
-	  For more details see Documentation/kdump/kdump.txt

-	help
-	  This gives the physical address where the kernel is loaded.
-
-	  If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
-	  bzImage will decompress itself to above physical address and
-	  run from there. Otherwise, bzImage will run from the address where
-	  it has been loaded by the boot loader and will ignore above physical
-	  address.
-
-	  In normal kdump cases one does not have to set/change this option
-	  as now bzImage can be compiled as a completely relocatable image
-	  (CONFIG_RELOCATABLE=y) and be used to load and run from a different
-	  address. This option is mainly useful for the folks who don't want
-	  to use a bzImage for capturing the crash dump and want to use a
-	  vmlinux instead. vmlinux is not relocatable hence a kernel needs
-	  to be specifically compiled to run from a specific memory area
-	  (normally a reserved region) and this option comes handy.
-
-	  So if you are using bzImage for capturing the crash dump, leave
-	  the value here unchanged to 0x100000 and set CONFIG_RELOCATABLE=y.
-	  Otherwise if you plan to use vmlinux for capturing the crash dump
-	  change this value to start of the reserved region (Typically 16MB
-	  0x1000000). In other words, it can be set based on the "X" value as
-	  specified in the "crashkernel=YM@XM" command line boot parameter
-	  passed to the panic-ed kernel. Typically this parameter is set as
-	  crashkernel=64M@16M. Please take a look at
-	  Documentation/kdump/kdump.txt for more details about crash dumps.
-
-	  Usage of bzImage for capturing the crash dump is recommended as
-	  one does not have to build two kernels. Same kernel can be used
-	  as production kernel and capture kernel. Above option should have
-	  gone away after relocatable bzImage support is introduced. But it
-	  is present because there are users out there who continue to use
-	  vmlinux for dump capture. This option should go away down the
-	  line.

-	  One use is for the kexec on panic case where the recovery kernel
-	  must live at a different physical address than the primary

- 	  If bootloader loads the kernel at a non-aligned address and

-
- 	  If bootloader loads the kernel at a non-aligned address and

- 	  load address and decompress itself to the address it has been
