From bc0c7ece6191d89f435e4e4016f74167430c6c21 Mon Sep 17 00:00:00 2001 From: Yuriy Kolerov Date: Mon, 12 Sep 2016 18:55:03 +0300 Subject: ARCv2: intc: Use kflag if STATUS32.IE must be reset In the end of "arc_init_IRQ" STATUS32.IE flag is going to be affected by "flag" instruction but "flag" never touches IE flag on ARCv2. So "kflag" instruction must be used instead of "flag".
