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

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

 188           This option removes the E2/R2 register from the set available to gcc
 189           for normal use and instead uses it to store the address of the
 190           current process's task_struct whilst in the kernel.
 191
 192           This means the kernel doesn't need to calculate the address each time
 193           "current" is used (take SP, AND with mask and dereference pointer
 194           just to get the address), and instead can just use E2+offset
 195           addressing each time.
