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.
