 125           This option determines the caching mode for the kernel.
 126
 127           Write-Back caching mode involves the all reads and writes causing
 128           the affected cacheline to be read into the cache first before being
 129           operated upon. Memory is not then updated by a write until the cache
 130           is filled and a cacheline needs to be displaced from the cache to
 131           make room. Only at that point is it written back.
 132
 133           Write-Through caching only fetches cachelines from memory on a
 134           read. Writes always get written directly to memory. If the affected
 135           cacheline is also in cache, it will be updated too.

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

 200           This option removes the E2/R2 register from the set available to gcc
 201           for normal use and instead uses it to store the address of the
 202           current process's task_struct whilst in the kernel.
 203
 204           This means the kernel doesn't need to calculate the address each time
 205           "current" is used (take SP, AND with mask and dereference pointer
 206           just to get the address), and instead can just use E2+offset
 207           addressing each time.
