Remove some configuration options that don't really make sense.

-CONFIG_FAST_IRQ
- Select this option in order to get the interrupts processed faster
- on your S/390 or zSeries machine. If selected, after an interrupt
- is processed, the channel subsystem will be asked for other pending
- interrupts which will also be processed before leaving the interrupt
- context. This speeds up the I/O a lot. Say "Y".

CONFIG_MACHCHK_WARNING
Select this option if you want the machine check handler on IBM S/390 or
zSeries to process warning machine checks (e.g. on power failures).
If unsure, say "Y".
-CONFIG_CHSC
- Select this option if you want the s390 common I/O layer to use information
- obtained by channel subsystem calls. This will enable Linux to process link
- failures and resource accessibility events. Moreover, if you have procfs
- enabled, you'll be able to toggle chpids logically offline and online. Even
- if you don't understand what this means, you should say "Y".

CONFIG_PROCESS_DEBUG
Say Y to print all process fault locations to the console. This is
a debugging option; you probably do not want to set it unless you
