On book3s/64, the only user of hugepd is hash in 4k mode.
All other setups (hash-64, radix-4, radix-64) use leaf PMD/PUD.

In that setup there are only two huge page sizes: 16M and 16G.

e500 supports many page sizes among which the following size are

The PAPR expects the TCE table to have no entries at the time of
unset window(i.e. remove-pe). The TCE clear right now is done
before freeing the iommu table. On pSeries, the unset window
makes those entries inaccessible to the OS and the H_PUT/GET calls
fail on them with H_CONSTRAINED.
On
This patch basically brings consistency with PowerNV approach
to use the first freely available iommu table when the default
window is removed.
The pSeries iommu code convention has been that the table[0] is
for the default 32 bit DMA window and the table[1] is for the
64 bit DDW.
With VFs
The ioctl VFIO_IOMMU_SPAPR_TCE_GET_INFO is not reporting the
actuals on the platform as not all the details are correctly
collected during the platform probe/scan into the iommu_table_group.
Collect the information during the device setup time as the DMA
window property is already looked up on
The PowerNV specific table_group_ops are defined in powernv/pci-ioda.c.
The pSeries specific table_group_ops are sitting in the generic powerpc
file. Move it to where it actually belong(pseries/iommu.c).
The functions are currently defined even for CONFIG_PPC_POWERNV
which are unused on PowerNV.
The patches reimplement the iommu table_group_ops for pSeries
for VFIO SPAPR TCE sub-driver thereby bringing consistency with
PowerNV implementation and getting rid of limitations/bugs which
were emanating from these differences on the earlier approach on
pSeries.

There is an issue with the hotplug operation when it's done on the
bridge/switch slot. The bridge-port and devices behind the bridge, which
become offline by hot-unplug operation, don't get hot-plugged/enabled by
doing hot-plug operation on that slot. Only the first port of the bridge
gets enabled
Description of the problem: The hotplug driver for powerpc
(pci/hotplug/pnv_php.c) gives kernel crash when we try to
hot-unplug/disable the PCIe switch/bridge from the PHB.
Root Cause of Crash: The crash is due to the reason that, though the msi
data structure has been released during
The fix of Powerpc hotplug driver (drivers/pci/hotplug/pnv_php.c)
addresses below two issues.
1. Kernel Crash during hot unplug of bridge/switch slot.
2. Bridge Support Enablement - Previously, when we do a hot-unplug
operation on a bridge slot, all the ports and devices behind the
bridge-ports

The I2S driver depends on the dmaengine parts

This is odd to say at least. Any chance you can check the value
of /sys/block/$DEVICE/queue/rotational for the relevant device before
and after this commit? And is this an ATA or NVMe SSD?
