VFIO implements platform independent stuff such as
a PCI driver, BAR access (via read/write on a file descriptor
or direct mapping when possible) and IRQ signaling.
The platform dependent part includes IOMMU initialization
and handling. This patch implements an IOMMU driver for VFIO
which does
This patch initializes IOMMU groups based on the IOMMU
configuration discovered during the PCI scan on POWERNV
(POWER non virtualized) platform. The IOMMU groups are
to be used later by VFIO driver (PCI pass through).
It also implements an API for mapping/unmapping pages for

This patch-set is created against your tree (next branch) and fixed the build
failure that you pointed.
Changes from the previous version:
- Changes for PPR save/restore in denorm_exception_hv,
data_access_slb_relon_pSeries and instruction_access_slb_relon_pSeries
exception vectors
[PATCH 1/6] powerpc: Move branch instruction from ACCOUNT_CPU_USER_ENTRY to
caller
The first instruction in ACCOUNT_CPU_USER_ENTRY is 'beq' which checks for
exceptions coming from kernel mode. PPR value will be saved immediately after
ACCOUNT_CPU_USER_ENTRY and is also for user level exceptions.
[PATCH 2/6] powerpc: Enable PPR save/restore
SMT thread status register (PPR) is used to set thread priority. This patch
enables PPR save/restore feature (CPU_FTR_HAS_PPR) on POWER7 and POWER8 systems.

[PATCH 4/6] powerpc: Define ppr in thread_struct
ppr in thread_struct is used to save PPR and restore it before process exits

This patch sets the default priority to 3 when tasks are created such
that users can use 4 for higher priority tasks.
