From 54ff328b46e58568c4b3350c2fa3223ef862e5a4 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 11 Jun 2009 10:33:09 +0300 Subject: sh: Tie sparseirq in to Kconfig. Now that the dependent patches are merged, we are ready to enable sparseirq support. This simply adds the Kconfig option, and then converts from the _cpu to the _node allocation routines to follow the upstream sparseirq API changes.
