Subject: [PATCH 5.10 027/152] riscv: Fixup CONFIG_GENERIC_TIME_VSYSCALL

From: Guo Ren <guoren@...ux.alibaba.com>

commit 0aa2ec8a475fb505fd98d93bbcf4e03beeeebcb6 upstream.

The patch fix commit: ad5d112 ("riscv: use vDSO common flow to
reduce the latency of the time-related functions").

The GENERIC_TIME_VSYSCALL should be CONFIG_GENERIC_TIME_VSYSCALL
or vgettimeofday won't work.
