 126           This option determines the caching mode for the kernel.
 127
 128           Write-Back caching mode involves the all reads and writes causing
 129           the affected cacheline to be read into the cache first before being
 130           operated upon. Memory is not then updated by a write until the cache
 131           is filled and a cacheline needs to be displaced from the cache to
 132           make room. Only at that point is it written back.
 133
 134           Write-Through caching only fetches cachelines from memory on a
 135           read. Writes always get written directly to memory. If the affected
 136           cacheline is also in cache, it will be updated too.

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

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

 233           The PCI-HOWTO, available from
 234           <http://www.tldp.org/docs.html#howto>, contains valuable
 235           information about which PCI hardware does work under Linux and which
 236           doesn't.
