Subject: [PATCH V2] selftests/vDSO: Add riscv getcpu & gettimeofday test
From: Guo Ren <guoren@...nel.org>
Enable vDSO getcpu & gettimeofday test for riscv. But only riscv64
supports __vdso_gettimeofday and riscv32 is under development.
VERSION
{
LINUX_4.15 {
global:
__vdso_rt_sigreturn;
__vdso_gettimeofday;
__vdso_clock_gettime;
__vdso_clock_getres;
__vdso_getcpu;
__vdso_flush_icache;
local: *;
};
