This patch makes qemu ignore unplug requests from the guest for pci
devices which are tagged as non-hotpluggable. Trouble spot is the
piix4 chipset with the ISA bridge. Requests to unplug that one will
make it go away together with all ISA bus devices, which are not
prepared to be unplugged and thus don't cleanup, leaving active
qemu timers behind in free'ed memory.

The e500 PCI controller isn't qdev'ified yet. This leads to severe issues
when running with -drive.
To be able to use a virtio disk with an e500 VM, let's convert the PCI
controller over to qdev.

The MPC8544DS board emulation was only used with KVM so far, so some
parts of the code didn't provide proper values for non-KVM execution.
This patch makes the machine work without KVM enabled. To actually use
this, you also need proper e500v2 MMU emulation.

The pSeries machine uses two tables to look up guest hcalls for emulation.
One of these is exactly one entry too small to hold all the hcalls it needs
to, leading to memory corruption.
This patch fixes the bug, and while we're at it, make both tables 'static'
since they're never used from other modules.

Currently the qemu pseries machine numbers its virtual serial devices
from 0. However, existing pSeries machines running pHyp number them from
0x30000000.
In theory these indices are arbitrary, since everything necessary for the
kernel to find them is advertised in the device tree. However the debian
installer, at least, incorrectly looks for a device named vty@30... to
determine whether to use the hypervisor console.
Therefore this patch moves the numbers we use to match the existing pHyp
practice, in order to workaround broken userspace apps of this type.

Currently, the qemu emulated pseries machine puts
"qemu,emulated-pSeries-LPAR" in the device tree's root level 'model'
property. Unfortunately this confuses some installers and ybin, which
expect this to start with "IBM" on pSeries machines. This patch addresses
this problem, making the property more closely resemble the pattern of
existing real hardware.

The original pSeries machine was limited to 32 CPUs, more or less

Prototype without "inline" keyword breaks the build with some gcc

Fix this by removing the inline keywork everywhere. Some functions
can't be inlined anyway as the are referenced using function pointers.

On IA32 host or IA32 PAE host, at present, generally, we can't create
an HVM guest with more than 2G memory, because generally it's almost
impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.
Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the
lock option, so mapcache will not unmap these ram_ptr.
Blocks that do not belong to the RAM, but usually to a device ROM or to
a framebuffer, are handled in a separate function. So the whole RAMBlock
can be map.
