The recent change to the vdso_data_store broke building compat VDSO
on at least arm64 because it includes headers outside of the include/vdso/
namespace:

I understand that powerpc64 also has an issue, see 
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20231221120410.2226678-1-mpe@ellerman.id.au/

Yeah, and that patch would silently conflict with this series, which is
not ideal.

I could delay merging my patch above until after this series goes in,
mine only fixes a fairly obscure build warning.

cheers
