 I haven't seen the .config, but CONFIG_RTC_CLASS=y

 It just don't have to be put in the default x86 config maybe,
 but it's legal..
 

 the device node creation is yet another option of the
 rtc class. it should be on by default in any defconfig, I'd guess.

 But then you'll get /dev/rtc0 without any specific device node.

 As I said in the past, I'd accept a patch to handle this special
 case of having /dev/rtc with a specific major and minor, but I'm against
 it.

 It would be better to upgrade your userspace when such big changes
 happens in the kernel. In fact, it the first time that the rtc
 has been touched in the last.. 10 year? I think it's not unreasonable to
 ask to upgrade userspace.

 wrto embedded systems, having worked with them for years, you are expected
 to check every detail of every new kernel you want to use before releasing
 it or, say, uploading it to your lander on the moon :)
