	  This can't be so easily used on SMP as the process that owns the FPU
	  state on a CPU may be currently running on another CPU, so for the

	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, like most personal computers, say N. If
	  you have a system with more than one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,
	  singleprocessor machines. On a singleprocessor machine, the kernel
	  will run faster if you say N here.

	  See also <file:Documentation/x86/i386/IO-APIC.txt>,
	  <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available at
	  <http://www.tldp.org/docs.html#howto>.

	  This option removes the E2/R2 register from the set available to gcc
	  for normal use and instead uses it to store the address of the
	  current process's task_struct whilst in the kernel.

	  This means the kernel doesn't need to calculate the address each time
	  "current" is used (take SP, AND with mask and dereference pointer
	  just to get the address), and instead can just use E2+offset
	  addressing each time.

	  This has no effect on userspace.
