From 35c2450191634bd0ac0ae3c6e9da3f590124e8e2 Mon Sep 17 00:00:00 2001 From: "Singh, Brijesh" Date: Mon, 1 Oct 2018 19:44:29 +0000 Subject: x86_iommu: move vtd_generate_msi_message in common file The vtd_generate_msi_message() in intel-iommu is used to construct a MSI Message from IRQ. A similar function will be needed when we add interrupt remapping support in amd-iommu. Moving the function in common file to avoid the code duplication. Rename it to x86_iommu_irq_to_msi_message(). There is no logic changes in the code flow. Signed-off-by: Brijesh Singh Suggested-by: Peter Xu Reviewed-by: Eduardo Habkost Cc: Peter Xu Cc: "Michael S.
