Subject: [PATCH] fix RTC_CLASS regression with PARISC
Date: Monday, September 8, 2008 - 11:53 am

As of 2.6.26, most distribution kernels for PARISC are coming with the
wrong RTC infrastructure enabled, meaning that userland can no longer
get at the RTC, so all our parisc clocks are drifting.

The fault is this patch:

commit c750090085f260503d8beec1c73c4d2e4fe93628

    rtc: avoid legacy drivers with generic framework

Which makes drivers/rtc take precedence over the generic rtc.  However,
for parisc we only have the generic rtc, so in essence this turns off
our ability to access the rtc.  Put it back again by making RTC_CLASS
unselectable if the architecture is parisc.
