# Placeholder file, no vDSO hwcap entries used in this kernel.
If that's the case, why package it at all?
There's no need for it. We just don't have a way (with .spec magic I know,
anyway) to decide at the right time whether we need one or not. The
kernel's 'make vdso_install' target either does or doesn't make one.
Except AFAIK none ever does at this point, apparently because the Xen
support it was there for fell out. There was a time when we thought that
the powerpc and/or s390 vDSOs might use the same mechanism too, but
apparently they never did try to do that.
Thanks,
