+       help
+         This driver allows usage of CHSC subchannels. A CHSC subchannel
+         is usually present on LPAR only.
+         The driver creates a device /dev/chsc, which may be used to
+         obtain I/O configuration information about the machine and
+         to issue asynchronous chsc commands (DANGEROUS).
+         You will usually only want to use this interface on a special
+         LPAR designated for system management.
+
+         To compile this driver as a module, choose M here: the
+         module will be called chsc_sch.
