| 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. |

| help |
| 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. |
