[PATCH 1/2] selftests/vDSO: Add support for LoongArch

From: Tiezhu Yang
Date: Fri Jun 09 2023 - 05:58:56 EST


There exist the following errors when build vDSO selftests on LoongArch:

# cd tools/testing/selftests/vDSO && make
...
error: 'VDSO_VERSION' undeclared (first use in this function)
...
error: 'VDSO_NAMES' undeclared (first use in this function)

We can see that VDSO_VERSION should be LINUX_5.10 and VDSO_NAMES should
be 1 for LoongArch in arch/loongarch/vdso/vdso.lds.S, add them to support
LoongArch.
