Correct the composition
Dear Arnd:
1. Setup an additional memory mapping for clock hardware in user space
when establishing vdso-needed memory mapping
In arch_setup_additional_pages(), kernel establishes memory
mapping for vdso's text and vdata page in user space. In order to make
clock hard

VDSO needs real-time cycle count to ensure the time accuracy.
Unlike others, nds32 architecture does not define clock source,
hence VDSO needs atcpit100 offering real-time cycle count
to derive the correct time.
