The SH RTC is a BCD RTC with some version having 4 digits for the year.
The range for the RTCs with only 2 digits for the year was unfortunately
shifted to handle 1999 to 2098.

The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.
Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
struct before requesting the IRQ.

There is no point in resetting the time to epoch as this means that
userspace will never get the valuable information that time is actually
invalid.

There is no point in caching alarm_time for .read_alarm because

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes
the common Kbuild.asm file. Factor out the duplicated include directives
to scripts/Makefile.asm-generic so that no architecture would opt out
of the mandatory-y mechanism.
um is not forced to include mandatory-y since it is a very exceptional
case which does not support UAPI.
