134 Enable this to be lazy in the saving of the FPU state to the owning

136 don't use the FPU as only those tasks that use it will pass it
137 between them, and the state needn't be saved for a task that isn't
138 using it.
139
140 This can't be so easily used on SMP as the process that owns the FPU
141 state on a CPU may be currently running on another CPU, so for the
142 moment, it is disabled.

187 This enables support for systems with more than one CPU. If you have
188 a system with only one CPU, like most personal computers, say N. If
189 you have a system with more than one CPU, say Y.
190
191 If you say N here, the kernel will run on single and multiprocessor
192 machines, but will use only one CPU of a multiprocessor machine. If
193 you say Y here, the kernel will run on many, but not all,
194 singleprocessor machines. On a singleprocessor machine, the kernel
195 will run faster if you say N here.

215 This option removes the E2/R2 register from the set available to gcc
216 for normal use and instead uses it to store the address of the
217 current process's task_struct whilst in the kernel.
218
219 This means the kernel doesn't need to calculate the address each time
220 "current" is used (take SP, AND with mask and dereference pointer
221 just to get the address), and instead can just use E2+offset
222 addressing each time.
