+Math emulation only kernel
+CONFIG_M68KFPU_EMU_ONLY
+ 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
+ needs to be executed whether a floating-point instruction in the
+ kernel should be executed or not.

+ mantissa and round slightly incorrect, what is more then enough

+ The kernel httpd acceleration daemon (kHTTPd) is a (limited)
