>Description:
	After the recent reshuffling of the clock chip drivers,
	the sparc64 clock.c driver depends on the presence of
	the mc146818 driver.  This caused a build problem for
	kernels configured for e.g. Ultra2 systems, where 'rtc at ebus'
	is not required (which otherwise pulls in the mc146818 driver).

	The build problem was fixed by files.sparc64 revision 1.86,
	but the clock driver should probably be somewhat restructured.

>How-To-Repeat:
	Try to revert files.sparc64 to 1.85, and watch the linking of
	the kernel fail with "undefined refrerence to `mc146818_attach'
	when 'rtc* at ebus?' is not present in the configuration file.

>Fix:
	Worked around by files.sparc64 revision 1.86, but this should
	probably be fixed in a better way.
