Subject: linux-next: build failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/linux/kernel.h:13:0,
                 from include/linux/interrupt.h:5,
                 from drivers/iommu/intel_irq_remapping.c:4:
drivers/iommu/intel_irq_remapping.c: In function 'intel_enable_irq_remapping':
drivers/iommu/intel_irq_remapping.c:656:48: error: 'eim' undeclared (first use in this function)
  pr_info("Enabled IRQ remapping in %s mode\n", eim ? "x2apic" : "xapic");
                                                ^

Caused by my mismerge :-(

I added this merge fix patch (and will fix the merge itself tomorrow):
