[PATCH v3 1/2] selftests/vDSO: Fix building errors on LoongArch

[Tiezhu Yang]

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.

[PATCH v3 2/2] selftests/vDSO: Fix runtime errors on LoongArch

[Tiezhu Yang]

It could not find __vdso_getcpu and __vdso_gettimeofday when test
getcpu and gettimeofday on LoongArch.

  # make headers && cd tools/testing/selftests/vDSO && make
  # ./vdso_test_getcpu
  Could not find __vdso_getcpu
  # ./vdso_test_gettimeofday
  Could not find __vdso_gettimeofday

One simple way is to add LoongArch case to define version and name,
just like commit d942f231afc0 ("selftests/vDSO: Add riscv getcpu &
gettimeofday test"), but it is not the best way.

Since each architecture has already defined names and versions in
vdso_config.h, it is proper to include vdso_config.h to get version
and name for all archs.

Hi Shuah, Andrew and Mark,

The patches still seem to apply cleanly.
Could you please review and merge them for the upcoming merge window?

People may be on vacation. I'm also waiting to hear back on my patches.
Lets see when they get back and start picking up patches.

This series has received Reviewed-by and Tested-by for two months,
since the merge window is coming soon, should it take through
shuah/linux-kselftest.git or akpm/mm.git?

Hi Andrew,

There is already a tag linux_kselftest-next-6.9-rc1 [1],
it seems no chance to merge them through kselftest tree,
would you be able to pick them up through your tree [2]?

"If you cannot find a maintainer for the subsystem you are
working on, Andrew Morton (akpm@linux-foundation.org) serves
as a maintainer of last resort."

Thanks,
