From a3c08e5d80c54e32423efbba113b02942c91f726 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 8 Oct 2010 20:24:58 +0200 Subject: x86: Convert irq_chip access to new functions Before moving the irq chips to the new functions, fixup direct callers. The cpu offline irq fixup code needs to become generic and archs need to honour the "force" flag as an indicator, but that's for later.
