From e15f6870a2f2a29abcdb910b80f9629bcf7f5566 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 2 Oct 2010 00:43:43 +0900 Subject: [PATCH] sh: Support userimask for all SH-X3 interrupt controllers. This shuffles some of the shared bits out of the 7786 code and in to a shared SH-X3 support file. Presently just for userimask, but also a good place for the IRQ balancing wrappers.
