pseries: savevm support with KVM

At present, the savevm / migration support for the pseries machine will not
work when KVM is enabled. That's because KVM manages the guest's hash page
table in the host kernel, so qemu has no visibility of it. This patch...

xics: rename types to be sane and follow coding style

Basically, in HW the layout of the interrupt network is:
- One ICP per processor thread (the "presenter"). This contains the
    registers to fetch a pending interrupt (ack), EOI, and control the...

pseries: savevm support for VIO devices

This patch adds helpers to allow PAPR VIO devices to save state common
to all VIO devices during savevm.

spapr-tce: make sPAPRTCETable a proper device

Model TCE tables as a device that's hooked up as a child object to
the owner. Besides the code cleanup, we get a few nice benefits:

1) free actually works now (it was dead code before)

2) the TCE information is visible in the device tree...

pseries: savevm support for pseries machine

This adds the necessary pieces to implement savevm / migration for the
pseries machine. The most complex part here is migrating the hash
table - for the paravirtualized pseries machine the guest's hash page
table is not stored within guest memory, but externally and the guest...

PPC: dbdma: Move processing to io

Soon we will introduce intermediate processing pauses which will
allow the bottom half to restart a DMA request that couldn't be
fulfilled yet.

For that to work, move the processing variable into the io struct
which is what DMA providers work with....

PPC: dbdma: Support unaligned DMA access

The DBDMA engine really just reads bytes from a producing device (IDE
in our case) and shoves these bytes into memory. It doesn't care whether
any alignment takes place or not.

Our code today however assumes that block accesses always happen on...

PPC: dbdma: Move defines into header file

We usually keep struct and constant definitions in header files. Move
them there to stay consistent and to make access to fields easier.

PPC: dbdma: Introduce kick function

The DBDMA engine really is running all the time, waiting for input. However
we don't want to waste cycles constantly polling.

So introduce a kick function that data providers can call to notify the
DBDMA controller of new input....

PPC: dbdma: Move static bh variable to device struct

The DBDMA controller has a bottom half to asynchronously process DMA
request queues.

This bh was stored as a gross static variable. Move it into the device
struct instead.

While at it, move all users of it to the new generic kick function....
