[Patch v2] iommu/vt-d: Adjsut the return value of the parse_ioapics_under_ir

Adjust the return value of parse_ioapics_under_ir as negative value representing failure and "0" representing succcess. Just make it consistent with other function implementation, and we can judge if calling is successfull by if (!parse_ioapics_under_ir()) style. Signed-off-by: Baoquan He --- v1-

[PATCH 7/8] iommu: Remove is_pci_dev() fall-back from iommu_group_get_for_dev

From: Joerg Roedel All callers of iommu_group_get_for_dev() provide a device_group call-back now, so this fall-back is no longer needed. Signed-off-by: Joerg Roedel --- drivers/iommu/iommu.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/drivers/iommu/iommu.c b/drivers/iommu/iommu.c inde

[PATCH 3/8] iommu: Add generic_device_group() function

[PATCH 8/8] iommu: Move default domain allocation to iommu_group_get_for_dev()

From: Joerg Roedel Now that the iommu core support for iommu groups is not pci-centric anymore, we can move default domain allocation to the bus independent iommu_group_get_for_dev() function. Signed-off-by: Joerg Roedel --- drivers/iommu/iommu.c | 18 ++ 1 file changed, 10 ins

[PATCH 1/8] iommu: Revive device_group iommu-ops call-back

From: Joerg Roedel That call-back is currently unused, change it into a call-back function for finding the right IOMMU group for a device. This is a first step to remove the hard-coded PCI dependency in the iommu-group code. Signed-off-by: Joerg Roedel --- drivers/iommu/iommu.c | 9 ++---

[PATCH 0/8] iommu: Make core iommu-groups code more generic

Hi, this patch-set makes the core code for managing iommu-groups more generic by lifting its dependencies on PCI. The core function iommu_group_get_for_dev() had a hard dev_is_pci() check in it, followed by PCI specific handling. This check is removed in favour of the the revived device_group() i

Linus, please pull from git://git.infradead.org/intel-iommu.git for-linus-20151021 This contains a single fix, for when the IOMMU API is used to overlay an existing mapping comprised of 4KiB pages, with a mapping that can use superpages. For the *first* superpage in the new mapping, we
