Tobias Klauser f3d60f2a25 riscv: Disable KSAN_SANITIZE for vDSO ... We use the generic C VDSO implementations of a handful of clock-related functions. When kasan is enabled this results in asan stub calls that are unlikely to be resolved by userspace, this just disables KASAN when building the VDSO. Verified the fix on a kernel with KASAN enabled using vDSO selftests.
