107	  Partitionable IBM Power5 ppc64 machines allow hosting of
108	  firmware virtual consoles from one Linux partition by

112	  this driver.

114	  To compile this driver as a module, choose M here: the
115	  module will be called hvcs.  Additionally, this module
116	  will depend on arch specific APIs exported from hvcserver.ko
117	  which will also be compiled when this driver is built as a
118	  module.
