Subject: [ 04/60] powerpc: On POWERNV enable PPC_DENORMALISATION by default

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anton Blanchard <anton@...ba.org>

commit 4e90a2a7375e86827541bda9393414c03e7721c6 upstream.

We want PPC_DENORMALISATION enabled when POWERNV is enabled,
so update the Kconfig.
