Mac-on-Linux has always lacked PPC64 host support. This is going to
change now!
This patchset contains minor patches to enable MOL, but is mostly about
bug fixes that came out of running Mac OS X. With this set and a pretty
small patch to MOL I have 10.4.11 running as a guest on a 970MP host.
On PowerPC we can go into MMU Split Mode. That means that either
data relocation is on but instruction relocation is off or vice
versa.
That mode didn't work properly, as we weren't always flushing
entries when going into a new split mode, potentially mapping
different code or data that we're
We emulate the mfsrin instruction already, that passes the SR number
in a register value. But we lacked support for mfsr that encoded the
SR number in the opcode.
So let's implement it.

sure the vcpu is actually loaded, so we're 100% sure we get the correct

When the guest activates the FPU, we load it up. That's fine when
it wasn't activated before on the host, but if it was we end up
reloading FPU values from last time the FPU was deactivated on the
host without writing the proper values back to the vcpu struct.
This patch checks if the FPU is
Userspace can tell us that it wants to trigger an interrupt. But
so far it can't tell us that it wants to stop triggering one.
So let's interpret the parameter to the ioctl that we have anyways
to tell us if we want to raise or lower the interrupt line.

BATs can't only be written to, you can also read them out!
So let's implement emulation for reading BAT values again.
While at it, I also made BAT setting flush the segment cache,
so we're absolutely sure there's no MMU state left when writing
BATs.

The FPU/Altivec/VSX enablement also brought access to some structure
elements that are only defined when the respective config options
are enabled.
Unfortuately I forgot to check for the config options at some places,
so let's do that now.
Unbreaks the build when CONFIG_VSX is not set.
Some times we don't want all capabilities to be available to all
our vcpus. One example for that is the OSI interface, implemented
in the next patch.
In order to have a generic mechanism in how to enable capabilities
individually, this patch introduces a new ioctl that can be used
for this
MOL uses its own hypercall interface to call back into userspace when
the guest wants to do something.
So let's implement that as an exit reason, specify it with a CAP and
only really use it when userspace wants us to.
The only user of it so far is MOL.

Mac OS X has some applications - namely the Finder - that require alignment
interrupts to work properly. So we need to implement them.
But the spec for 970 and 750 also looks different. While 750 requires the
DSISR fields to reflect some instruction bits, the 970 declares this as an
optional
