Upstream libc has recently changed to start using
FUTEX_WAIT_BITSET instead of FUTEX_WAIT and this
is causing do_futex to return -TARGET_ENOSYS.
Pass bitset in val3 to sys_futex which will be
ignored by kernel for the FUTEX_WAIT case.

Currently, for the pseries machine the device tree supplied by qemu to SLOF
and from there to the guest does not include a 'compatible property' at the
root level. Usually that works fine, since in this case the compatible
property doesn't really give any information not already found in the
'device_type' or 'model' properties.
However, the lack of 'compatible' confuses the bootloader install in the
SLES11 SP2 and SLES11 SP3 installers. This patch therefore adds a token
'compatible' property to work around that.

This avoids assigning individual class fields and contributors
forgetting to add field assignments in KVM-only code.
ppc_cpu_class_find_by_pvr() requires the CPU model classes to be
registered, so defer host CPU type registration to kvm_arch_init().
Only register the host CPU type if there is a class with matching PVR.

Currently qemu does not get and put the state of the floating point and
vector registers to KVM. This is obviously a problem for savevm, as well
as possibly being problematic for debugging of FP-using guests.
This patch fixes this by using new extensions to the ONE_REG interface to
synchronize the qemu floating point state with KVM.

Currently when runing under KVM on ppc, we synchronize a certain number of
vital SPRs to KVM through the SET_SREGS call. This leaves out quite a lot
of important SPRs which are maintained in KVM. It would be helpful to
have their contents in qemu for debugging purposes, and when we implement
migration it will be vital, since they include important guest state that
will need to be restored on the target.
This patch sets up for synchronization of any registers supported by the
KVM ONE_REG calls. A new variant on spr_register() allows a ONE_REG id to
be stored with the SPR information. When we set/get information to KVM
we also synchronize any SPRs so registered.
For now we set this mechanism up to synchronize a handful of important
registers that already have ONE_REG IDs, notably the DAR and DSISR.

The current elf loader uses too much memory. For example, I have a
executable with a bss section of 400 MB and I set the ram size to 512
MB. Qemu uses about 780MB of RAM (which is fine), but there's a peak at
1.6 GB during initialization (this is not fine).
This patch fixes two things:
1) do not allocate each elf program twice.
2) do not allocate memory for areas that are only zeros.
For this we need a new field in Rom: "datasize" which is the size of the
allocated data. If datasize is less than romsize, it means that the area
from datasize to romsize is filled with zeros.
