Correct handling of NaNs for VFP VMLA, VMLS, VNMLS and VNMLA requires that
we implement the set of negations and additions specified by the ARM ARM;
plausible looking simplifications like turning (-A + B) into (B - A) or
computing (A + B) rather than (B + A) result in selecting the wrong NaN or
returning a NaN with the wrong sign bit.

Phillip Merensky reported that the special keys (e.g. Ctrl-Alt-f for full
screen) did not work correctly if -alt-grab is used.
BUG: 696530
Review of ui/sdl.c:sdl_refresh indicates that this is the intended behaviour,
so we should update the documentation to match the actual behaviour, as
suggested by Phillip in the bug report.

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.

Now that we have some nice helpers that can find us a TLB entry, let's
use that on the machine initialization code, so we don't need to know

Most of the code to support e500 style MMUs is already in place, but
we're missing on some of the special TLB0-TLB1 handling code and slightly
different TLB modification.
This patch adds support for the FSL style MMU.

To enable quick runtime detection of instruction groups to the currently
selected CPU emulation, we have a feature mask of what exactly the respective
instruction supports.
This feature mask is 64 bits long and we just successfully exceeded those 64
bits. To add more features, we need to think of something.
The easiest solution that came to my mind was to simply add another 64 bits
that we can also match on. Since the comparison is only done on start of the
qemu process to generate an internal opcode calling table, we should be fine
on any performance penalties here.

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.

On PPC, the default PAGE_SIZE is 64kb. Unfortunately, the hardware
alignments don't match here: There are RAM and MMIO regions within
a single page when it's 64kb in size.
So the only way out for now is to tell the user that he should use 4k
PAGE_SIZE.
This patch gives the user a hint on that, telling him that failing to
register a prefix slot is most likely to be caused by mismatching PAGE_SIZE.
This way it's also more future-proof, as bigger PAGE_SIZE can easily be
supported by other machines then, as long as they stick to 64kb granularities.

When compiling Qemu with older kernel headers, the PVR setting
mechanism isn't available yet. Unfortunately, back then I didn't add
a capability we could check against, so all we can do is add a configure
test to see if we support PVR setting. For BookE, we don't care yet.
This fixes compilation errors with KVM enabled on older kernel headers
(like 2.6.32).

Classic/server ppc has had SREGS for a while now (though I think not
always?), but it's still missing for booke. Check the capability before
calling KVM_SET_SREGS.
Without this, booke kvm fails to boot as of commit
84b4915dd2c0eaa86c970ffc42a68ea8ba9e48b5 (kvm: Handle kvm_init_vcpu
errors).
Also, don't write random stack state into the non-PVR sregs fields --
have kvm fill it in first.
Eventually booke will have sregs and it will have its own capability to
be tested here. However, we will want a way for platform code to request
to look like the actual CPU we're running on, especially if SoC devices
are being directly assigned.

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
arbitrarily. Particularly when we get SMT KVM guests it will be
pretty easy to exceed this. Therefore, raise the max number of CPUs
in a pseries machine guest to 256.
