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