When releasing PE for SRIOV VF, the PE is forced to be frozen
wrongly. When the same PE is picked for another VF, it won't
work anyhow. The patch fixes the issue by unfreezing, not
freezing the VF PE when releasing it.

There is a RCPM (Run Control/Power Management) in Freescale QorIQ
series processors. The device performs tasks associated with device
run control and power management.
The driver implements some features: mask/unmask irq, enter/exit low
power states, freeze time base, etc.

If using the symbol table, symbol addresses are not being fixed up

ppc64 ELF ABIv2 has a Global Entry Point (GEP) and a Local Entry Point

encoded in st_other.

Use symbol table lookups by default if DWARF is not necessary, since

So will it be correct to say that memory hotplug to memory-less node
isn't supported by PowerPC kernel ? Should I enforce the same in QEMU

To support "hybrid" DMA ops in a subsequent patch, we will need both
a direct DMA offset and an iommu pointer. Those are currently exclusive
(a union), so change them to be separate fields.
While there, also type iommu_table_base properly and make exist only

Now that the table and the offset can co-exist, we no longer need
to flip/flop, we can just establish both once at boot time.

This patch adds the ability to the DMA direct ops to fallback to the IOMMU
ops for coherent alloc/free if the coherent mask of the device isn't
suitable for accessing the direct DMA space and the device also happens
to have an active IOMMU table.

On some archs, the local clockevent device stops in deep cpuidle states.
The broadcast framework is used to wakeup cpus in these idle states, in
which either an external clockevent device is used to send wakeup ipis
or the hrtimer broadcast framework kicks in in the absence of such a
device. One cp
