[PATCH] parisc: Only call VDSO32_SYMBOL() when valid
Thomas Weißschuh <[email protected]>
| Newsgroups | org.kernel.vger.linux-parisc,org.kernel.vger.linux-kernel |
|---|---|
| Message-ID | <[email protected]> |
The definitions used by VDSO32_SYMBOL() only work if the 32-bit vDSO
actually exists.
Fixes: 3dce91790205 ("parisc: Allow to build without VDSO32")
