Fixed a couple of typos, long lines and referred to the documentation file.

bool "CPU isolation"
help
- This option enables support for CPU isolation.
- If enabled the kernel will try to avoid kernel activity on the
isolated CPUs.
- By default user-space threads are not scheduled on the isolated CPUs
unless
- they explicitly request it (via sched_ and pthread_ affinity calls).
Isolated
- CPUs are not subject to the scheduler load-balancing algorithms.
-
- CPUs can be marked as isolated using 'isolcpus=' command line option
or by
- writing '1' into /sys/devices/system/cpu/cpuN/isolated.

- This feature is useful for hard realtime and high performance
applications.
