I usually try to check linux-next at least once a week, but sometimes
it's more or less often.  At the moment I'm trying to track something
weird down but it seems like it has some userspace component to it.
I'll post a separate thread if I find a kernel problem there.

Aside from the RTC, my biggest problem right now is that reboot
stopped working at the same time as the common clock.  The
exynos5_restart() function is essentially behaving as a no-op since
the clock to the IP block that handles reset has been gated.  :(  The
bit "CLK_PMU_APBIF" is gated in "CLK_GATE_IP_PERIS". This used to be
ungated in exynos5_clk_ip_peris_ctrl().

I'm happy to test a patch that fixes this but I haven't yet had time
to try to fix it cleanly myself.
