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

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

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

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