+          instructions to be emulated by the kernel on machines that lack a
+          floating-point math coprocessor.  Thrill-seekers and chronically

+          floating point context anymore during task switches, so this
+          kernel will only be usable on machines without a floating-point
+          math coprocessor. This makes the kernel a bit faster as no tests

+          Note that the answer to this question won't directly affect the

+          cause serious problems on any Amiga or Atari Medusa if set. The only

+          The 68060 generally uses copyback caching of recently accessed data.

-          cards, you need to say Y here and also to "CardBus support" below.

-
-config M68KFPU_EMU_ONLY

-        help
-          This option prevents any floating-point instructions from being
-          compiled into the kernel, thereby the kernel doesn't save any
-          floating point context anymore during task switches, so this
-          kernel will only be usable on machines without a floating-point
-          math coprocessor. This makes the kernel a bit faster as no tests

-          it possible for you to improve performance somewhat if you know what
-          you are doing.
-
-          Note that the answer to this question won't directly affect the

-        ---help---
-          This allows to use certain instructions that work with indivisible
-          read-modify-write bus cycles. While this is faster than the
-          workaround of disabling interrupts, it can conflict with DMA
-          ( = direct memory access) on many Amiga systems, and it is also said
-          to destabilize other machines. It is very likely that this will
-          cause serious problems on any Amiga or Atari Medusa if set. The only
-          configuration where it should work are 68030-based Ataris, where it
-          apparently improves performance. But you've been warned! Unless you
-          really know what you are doing, say N. Try Y only if you're quite

-        ---help---
-          The 68060 generally uses copyback caching of recently accessed data.
-          Copyback caching means that memory writes will be held in an on-chip
-          cache and only written back to memory some time later.  Saying Y
-          here will force supervisor (kernel) accesses to use writethrough
-          caching.  Writethrough caching means that data is written to memory
-          straight away, so that cache and memory data always agree.
-          Writethrough caching is less efficient, but is needed for some
-          drivers on 68060 based systems where the 68060 bus snooping signal
-          is hardwired on.  The 53c710 SCSI driver is known to suffer from
