 167         help
 168           This option reduces the latency of the kernel when reacting to
 169           real-time or interactive events by allowing a low priority process to
 170           be preempted even if it is in kernel mode executing a system call.
 171           This allows applications to run more reliably even when the system is
 172           under load.
 173
 174           Say Y here if you are building a kernel for a desktop, embedded

 181           This option removes the E2/R2 register from the set available to gcc
 182           for normal use and instead uses it to store the address of the
 183           current process's task_struct whilst in the kernel.
 184
 185           This means the kernel doesn't need to calculate the address each time
 186           "current" is used (take SP, AND with mask and dereference pointer
 187           just to get the address), and instead can just use E2+offset
 188           addressing each time.

 198           single-stepping, which are taken over completely by the JTAG unit.

 224           The PCI-HOWTO, available from
 225           <http://www.tldp.org/docs.html#howto>, contains valuable

 227           doesn't.
