Patch series "selftests/vDSO: Fix errors on LoongArch", v4.
This patch (of 2):
There exist the following errors when build vDSO selftests on LoongArch:
# make headers && 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 the following code in arch/loongarch/vdso/vdso.lds.S:
VERSION
{
LINUX_5.10 {
global:
__vdso_getcpu;
__vdso_clock_getres;
__vdso_clock_gettime;
__vdso_gettimeofday;
__vdso_rt_sigreturn;
local: *;
};
}
so VDSO_VERSION should be 6 and VDSO_NAMES should be 1 for LoongArch,
add them to fix the building errors on LoongArch.
