128 Enable this to be lazy in the saving of the FPU state to the owning
129 task's thread struct. This is useful if most tasks on the system
130 don't use the FPU as only those tasks that use it will pass it
131 between them, and the state needn't be saved for a task that isn't
132 using it.
133
134 This can't be so easily used on SMP as the process that owns the FPU
135 state on a CPU may be currently running on another CPU, so for the
136 moment, it is disabled.

181 This enables support for systems with more than one CPU. If you have
182 a system with only one CPU, like most personal computers, say N. If
183 you have a system with more than one CPU, say Y.
184
185 If you say N here, the kernel will run on single and multiprocessor
186 machines, but will use only one CPU of a multiprocessor machine. If
187 you say Y here, the kernel will run on many, but not all,
188 singleprocessor machines. On a singleprocessor machine, the kernel
189 will run faster if you say N here.

209 This option removes the E2/R2 register from the set available to gcc
210 for normal use and instead uses it to store the address of the
211 current process's task_struct whilst in the kernel.
212
213 This means the kernel doesn't need to calculate the address each time
214 "current" is used (take SP, AND with mask and dereference pointer
215 just to get the address), and instead can just use E2+offset
216 addressing each time.
