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

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

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

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