Subject: uml: GENERIC_TIME support
From: Jeff Dike <jdike@xxxxxxxxxxx>
Enable CONFIG_GENERIC_TIME.
As a side-effect of this, the UML implementations of do_gettimeofday and
do_settimeofday go away, as these are provided by generic code. set_time also
goes away since it was only used by do_settimeofday.
