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