 143           This option determines the caching mode for the kernel.
 144
 145           Write-Back caching mode involves the all reads and writes causing
 146           the affected cacheline to be read into the cache first before being
 147           operated upon. Memory is not then updated by a write until the cache
 148           is filled and a cacheline needs to be displaced from the cache to
 149           make room. Only at that point is it written back.
 150
 151           Write-Through caching only fetches cachelines from memory on a
 152           read. Writes always get written directly to memory. If the affected
 153           cacheline is also in cache, it will be updated too.

 193         help
 194           This option reduces the latency of the kernel when reacting to
 195           real-time or interactive events by allowing a low priority process to
 196           be preempted even if it is in kernel mode executing a system call.
 197           This allows applications to run more reliably even when the system is
 198           under load.
 199
 200           Say Y here if you are building a kernel for a desktop, embedded

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

 253           doesn't.
