This reverts commit 518c7fb44f2182cde943dc64f88cb2fd4e4ff6b5. It breaks
new Linux guests with SMP, because IPIs get mapped to large vectors which
our MPIC emulation does not implement.

This gives the kernel a paravirtualized machine to target, without
requiring both sides to pretend to be targeting a specific board
that likely has little to do with the host in KVM scenarios. This
avoids the need to add new boards to QEMU, just to be able to
run KVM on new CPUs.

spapr_populate_pci_devices() populates the device tree only with bus

0cdd3d1444 fixed reading back the counter load time from the kernel
while assuming the kernel would always update its load time on writing
the state. That is only true for channel 1, and so pit_get_channel_info
returned wrong output pin states for high counter values.
Fix this by applying the offset also on kvm_pit_put. Now we also need to
update the offset when we write the state while the VM is stopped as it
keeps on changing in that state.

To prepare the final fix for clock calibration issues with the in-kernel
PIT, we want to cache the offset between vmclock and the clock used by
the in-kernel PIT. So far, we only need to update it when the VM state
changes between running and stopped because we only read the in-kernel
PIT state while the VM is running.

Emitted when the guest makes a request to enter S4 state.
There are three possible ways of having this event, as described here:
http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html
I've decided to add a new event and make it indepedent of SHUTDOWN.
This means that the SHUTDOWN event will eventually follow the
SUSPEND_DISK event.
I've choosen this way because of two reasons:
1. Having an indepedent event makes it possible to query for its
existence by using query-events
2. In the future, we may allow the user to change what QEMU should
do as a result of the guest entering S4. So it's a good idea to
keep both events separated

Fix an incorrect default value for the num-irqs property (we were
attempting to override it from the default set by the parent class
but not succeeding, which meant that the lm3s6965evb model would
assert on startup attempting to wire up nonexistent irq lines).
Instead of trying to override the parent's Property array, we
define an instance_init function which runs after default setup
but before user property setting and can just fix up the default
value in the gic_state struct.

kvm_allows_irq0_override() is a totally x86 specific concept:
move it to the target-specific source file where it belongs.
This means we need a new header file for the prototype:

Re-implemented the interconnect between the Xilinx AXI ethernet and DMA
controllers. A QOM interface "stream" is created, for the two stream interfaces.
As per Edgars request, this is designed to be more generic than AXI-stream,
so in the future we may see more clients of this interface beyond AXI stream.
This is based primarily on Paolos original refactoring of the interconnect.

I noticed that in hw/ide/ahci:ahci_dma_rw_buf() we do not free the sglist. Thus,
I've added a call to qemu_sglist_destroy() to fix this memory leak.

fields, in case there is some other codepath that tries to free the sglist.

While testing q35, which has its cdrom attached to the ahci controller, I found
that the Fedora 17 install would panic on boot. The panic occurs while
squashfs is trying to read from the cdrom. The errors are:
[ 8.622711] SQUASHFS error: xz_dec_run error, data probably corrupt
[ 8.625180] SQUASHFS error: squashfs_read_data failed to read block
0x20be48a
I was also able to produce corrupt data reads using an installed piix based
qemu machine, using 'dd'. I found that the corruptions were only occuring when
then read size was greater than 128k. For example, the following command
results in corrupted reads:
dd if=/dev/sr0 of=/tmp/blah bs=256k iflag=direct
The > 128k size reads exercise a different code path than 128k and below. In
ide_atapi_cmd_read_dma_cb() s->io_buffer_size is capped at 128k. Thus,
ide_atapi_cmd_read_dma_cb() is called a second time when the read is > 128k.
However, ahci_dma_rw_buf() restart the read from offset 0, instead of at 128k.
Thus, resulting in a corrupted read.
To fix this, I've introduced 'io_buffer_offset' field in IDEState to keep
track of the offset. I've also modified ahci_populate_sglist() to take a new
3rd offset argument, so that the sglist is property initialized.
I've tested this patch using 'dd' testing, and Fedora 17 now correctly boots
and installs on q35 with the cdrom ahci controller.

Leaving the aiocb to a non-NULL value leads to an assertion failure when
rerror/werror are set to stop or enospc, and the operation is retried.
scsi-disk checks that the aiocb member is NULL before filling it.
This patch correctly resets the aiocb to NULL values everywhere,
and adds the dual assertion that the aiocb was non-NULL before
calling bdrv_acct_done.

This patch fixes a problem in handling task management functions
in virtio-scsi. The cause of the problem is a mismatch between
the size of the tag in QEMU (32-bit) and virtio-scsi (64-bit).
Changing the QEMU size is hard because the migration format
uses 32 bits to store the tag; so just don't use the QEMU tag
(virtio-scsi only uses the tag for task management functions
anyway) and look up the full 64-bit tag in the hba_private field.
The reproducer is a bit obscure. If you cause an I/O timeout
(for example with rerror=stop and doing 'cont' on the monitor
continuously without fixing the error), sooner or later the
guest will try to abort the command and reissue it. At this
point, QEMU will report _two_ errors instead of one when you
hit 'c', because the first error has not been canceled correctly.
