 129           This option determines the caching mode for the kernel.
 130
 131           Write-Back caching mode involves the all reads and writes causing
 132           the affected cacheline to be read into the cache first before being
 133           operated upon. Memory is not then updated by a write until the cache
 134           is filled and a cacheline needs to be displaced from the cache to
 135           make room. Only at that point is it written back.
 136
 137           Write-Through caching only fetches cachelines from memory on a
 138           read. Writes always get written directly to memory. If the affected
 139           cacheline is also in cache, it will be updated too.

 180           This option reduces the latency of the kernel when reacting to
 181           real-time or interactive events by allowing a low priority process to
 182           be preempted even if it is in kernel mode executing a system call.
 183           This allows applications to run more reliably even when the system is
 184           under load.

 204           This option removes the E2/R2 register from the set available to gcc
 205           for normal use and instead uses it to store the address of the
 206           current process's task_struct whilst in the kernel.
 207
 208           This means the kernel doesn't need to calculate the address each time
 209           "current" is used (take SP, AND with mask and dereference pointer
 210           just to get the address), and instead can just use E2+offset
 211           addressing each time.
