 121           This option determines the caching mode for the kernel.
 122
 123           Write-Back caching mode involves the all reads and writes causing
 124           the affected cacheline to be read into the cache first before being
 125           operated upon. Memory is not then updated by a write until the cache
 126           is filled and a cacheline needs to be displaced from the cache to
 127           make room. Only at that point is it written back.
 128
 129           Write-Through caching only fetches cachelines from memory on a
 130           read. Writes always get written directly to memory. If the affected
 131           cacheline is also in cache, it will be updated too.

 171         help
 172           This option reduces the latency of the kernel when reacting to
 173           real-time or interactive events by allowing a low priority process to
 174           be preempted even if it is in kernel mode executing a system call.
 175           This allows applications to run more reliably even when the system is
 176           under load.
 177
 178           Say Y here if you are building a kernel for a desktop, embedded

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