milkymist-pfpu: fix GCC 5.0.0 aggressive-loop-optimizations warning
man gcc:
Warn if in a loop with constant number of iterations the compiler
detects undefined behavior in some statement during one or more of
the iterations.
Milkymist pfpu has no jump instructions, so checking for MICROCODE_WORDS
instructions should have kept us in bounds of s->microcode, but i++
allowed one loop too many,
hw/misc/milkymist-pfpu.c: In function ‘pfpu_write’:
hw/misc/milkymist-pfpu.c:365:20: error: loop exit may only be reached after undefined behavior [-Werror=aggressive-loop-optimizations]
if (i++ >= MICROCODE_WORDS) {
^
hw/misc/milkymist-pfpu.c:167:14: note: possible undefined statement is here
uint32_t insn = s->microcode[pc];
^
The code can still access out of bounds, because it presumes that PC register
always begins at 0, and we allow writing to it.

The patch defines constants used by EEH RTAS calls and adds

eeh_configure}, which are going to be used as follows:
* RTAS calls are received in spapr_pci.c, sanity check is done
there.
* RTAS handlers handle what they can. If there is something it
cannot handle and the corresponding sPAPRPHBClass callback is
defined, it is called.
* Those callbacks are only implemented for VFIO now. They do ioctl()
to the IOMMU container fd to complete the calls. Error codes from
that ioctl() are transferred back to the guest.

target-ppc: Add versions to server CPU descriptions
5b79b1c "target-ppc: Create versionless CPU class per family if KVM" added
a dynamic CPU class registration with the name of the CPU family which
QEMU is running on. For example, this allowed specifying "-cpu POWER7"
on every version of POWER7 machine, not just the one which POWER7 was
an alias of. I.e. before
5b79b1c, "-cpu POWER7" would not work on real
POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8.
However that patch broke POWER5+ support as POWER5+ CPU uses the same
name as the CPU class so dynamic registering of the POWER5+ class failed.
This redefines POWER5+ server CPUs by adding a version to them and adding
an alias for TCG case. KVM will use dynamically registered CPUs.
While we are here, do the same for 970 CPU.

PPC: Introduce the Virtual Time Base (VTB) SPR register
This patch adds basic support for the VTB.
PowerISA:
The Virtual Time Base (VTB) is a 64-bit incrementing counter.
Virtual Time Base increments at the same rate as the Time Base until its value
becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value
becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when
this occurs.
The operation of the Virtual Time Base has the following additional
properties.
1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of
the Virtual Time Base.
2. Copying the contents of a GPR to the Virtual Time Base replaces the
contents of the Virtual Time Base with the contents of the GPR.

The initial creation of the PAPR RTC qdev class left a wart - the rtc's

This patch moves it into the RTC device's own state structure, were it
belongs. This requires a small change to the migration stream format. In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.
Since we're changing the migration format, this also takes the opportunity
to:
* Change the rtc offset from a value in seconds to a value in
nanoseconds, allowing nanosecond offsets between host and guest
rtc time, if desired.
* Remove both the already unused "next_irq" field and now unused

modern devices might want bigger 64bit BARs.
This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.
The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.
The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.

pseries: Limit PCI host bridge "index" value
pseries guests can have large numbers of PCI host bridges. To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.
There are some problems with the details at present:
* The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
* No limit is imposed on the "index" property and large values can
translate to extremely large window addresses. With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.
This patch addresses this, by making "index" unsigned, and imposing a
limit. Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being. It's fairly easy to extend if
we discover we need more.

virtio-balloon: Fix balloon not working correctly when hotplug memory
When do memory balloon, it takes the 'ram_size' as the VM's current ram size,
But 'ram_size' is the startup configured ram size, it does not take into
account the hotplugged memory.
As a result, the balloon result will be confused.
Steps to reproduce:
(1)Start VM: qemu -m size=1024,slots=4,maxmem=8G
(2)In VM: #free -m : 1024M
(3)qmp balloon 512M
(4)In VM: #free -m : 512M
(5)hotplug pc-dimm 1G
(6)In VM: #free -m : 1512M
(7)qmp balloon 256M
(8)In VM: #free -m :1256M
We expect the VM's available ram size to be 256M after 'qmp balloon 256M'
command, but VM's real available ram size is 1256M.
For "qmp balloon" is not performance critical code, we use function
'get_current_ram_size' to get VM's current ram size.

pc-dimm: add a function to calculate VM's current RAM size
The global parameter 'ram_size' does not take into account
the hotplugged memory.
In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.
Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory devices and also plus ram_size.
