We should also test timedrift for Linux guests especially for guest
with pvclock. So this patch enable the timedrift for linux guests.
Changes from v1:
- Correct the wrong name for guest load cleaning
- Use -no-kvm-pit-reinjection for linux guests and -rtc-td-hack for
windows guests.

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.
On most systems we need to emulate dcbz when running 32 bit guests. So
far we've been rather slack, not giving correct DSISR values to the guest.
This patch makes the emulation more accurate, introducing a difference
between page not mapped and write protection fault. While at it, it
also speeds
Bool defaults to at least byte width. We usually only want to waste a single
bit on this. So let's move all the bool values to bitfields, potentially
saving memory.

Some HTAB providers (namely the PS3) ignore the SECONDARY flag. They
just put an entry in the htab as secondary when they see fit.
So we need to check the return value of htab_insert to remember the
correct slot id so we can actually invalidate the entry again.
Fixes KVM on the PS3.
Cell can't handle MSR_FE0 and MSR_FE1 too well. It gets dog slow.
So let's just override the guest whenever we see one of the two and mask them
out. See commit ddf5f75a16b3e7460ffee881795aa168dffcd0cf for reference.

Mac OS X uses the dcba instruction. According to the specification it doesn't
guarantee any functionality, so let's just emulate it as nop.

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.

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
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.

We have a 32 bit value in the PACA to store XER in. We also do an stw
when storing XER in there. But then we load it with ld, completely
screwing it up on every entry.

This patch makes the VSID of mapped pages always reflecting all special cases
we have, like split mode.
It also changes the tlbie mask to 0x0000 according to the spec. The mask
we used before was incorrect.

Some constants were bigger than ints. Let's mark them as such so we don't

When trying to read or store vcpu register data, we should also make
sure the vcpu is actually loaded, so we're 100% sure we get the correct

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 and DAR fields to reflect some instruction bits (DSISR) and the fault

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 the
current svn version of MOL I have 10.4.11 running as a guest on a 970MP

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.

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.

We get MMIOs with the weirdest instructions. But every time we do,
we need to improve our emulator to implement them.
So let's do that - this time it's lbzux and lhax's round.

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.
