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

 183         help
 184           This option reduces the latency of the kernel when reacting to
 185           real-time or interactive events by allowing a low priority process to
 186           be preempted even if it is in kernel mode executing a system call.
 187           This allows applications to run more reliably even when the system is
 188           under load.
 189
 190           Say Y here if you are building a kernel for a desktop, embedded
 191           or real-time system.  Say N if you are unsure.

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

 239
 240           The PCI-HOWTO, available from
 241           <http://www.tldp.org/docs.html#howto>, contains valuable
 242           information about which PCI hardware does work under Linux and which
 243           doesn't.
