 129           This option determines the caching mode for the kernel.
 130
 131           Write-Back caching mode involves the all reads and writes causing
 132           the affected cacheline to be read into the cache first before being
 133           operated upon. Memory is not then updated by a write until the cache
 134           is filled and a cacheline needs to be displaced from the cache to
 135           make room. Only at that point is it written back.
 136
 137           Write-Through caching only fetches cachelines from memory on a
 138           read. Writes always get written directly to memory. If the affected
 139           cacheline is also in cache, it will be updated too.

 179         help
 180           This option reduces the latency of the kernel when reacting to
 181           real-time or interactive events by allowing a low priority process to
 182           be preempted even if it is in kernel mode executing a system call.
 183           This allows applications to run more reliably even when the system is
 184           under load.
 185
 186           Say Y here if you are building a kernel for a desktop, embedded
 187           or real-time system.  Say N if you are unsure.

 193           This option removes the E2/R2 register from the set available to gcc
 194           for normal use and instead uses it to store the address of the
 195           current process's task_struct whilst in the kernel.
 196
 197           This means the kernel doesn't need to calculate the address each time
 198           "current" is used (take SP, AND with mask and dereference pointer
 199           just to get the address), and instead can just use E2+offset
 200           addressing each time.

 234           of these boards and you wish to use the PCI facilities, say Y here.
 235
 236           The PCI-HOWTO, available from
 237           <http://www.tldp.org/docs.html#howto>, contains valuable
 238           information about which PCI hardware does work under Linux and which
 239           doesn't.
