2013-12-10net/cadence_gem: Fix register w1c logicPeter Crosthwaite
This write-1-clear logic was incorrect. It was always clearing w1c bits regardless of whether the written value was 1 or not. i.e. it was implementing a write-anything-to-clear strategy.

2013-12-10target-arm: Allow secondary KVM CPUs to be booted via PSCIPeter Maydell
New ARM boards are generally expected to boot their secondary CPUs via the PSCI interface, rather than ad-hoc "loop around in holding pen code" as hw/arm/boot.c implements. In particular this is necessary for mach-virt kernels. For KVM we achieve this by creating the VCPUs with a feature flag marking them as starting in PSCI powered-down state; the guest kernel will then make a PSCI call (implemented in the host kernel) to start the secondaries at an address of its choosing once it has got the primary CPU up. Implement this setting of the feature flag, controlled by a qdev property for ARMCPU, which board code can set if it is a PSCI system.

2013-12-10device_tree.c: Terminate the empty reservemap in create_device_tree()Peter Maydell
Device trees created with create_device_tree() may not have any entries in their reservemap, because the FDT API requires that the reservemap is completed before any FDT nodes are added, and create_device_tree() itself creates a node. However we were not calling fdt_finish_reservemap(), which meant that there was no terminator in the reservemap list and whatever happened to be at the start of the FDT data section would end up being interpreted as reservemap entries. Avoid this by calling fdt_finish_reservemap() to add the terminator.

2013-12-10target-arm: Provide mechanism for getting KVM constants even if not CONFIG_KVMPeter Maydell
There are a number of places where it would be convenient for ARM code to have working definitions of KVM constants even in code which is compiled with CONFIG_KVM not set. In this situation we can't simply include the kernel KVM headers (which might conflict with host header definitions or not even compile on the compiler we're using) so we have to redefine equivalent constants. Provide a mechanism for doing this and checking that the values match, and use it for the constants we're currently exposing via an ad-hoc mechanism.

2013-12-06vfio-pci: Release all MSI-X vectors when disabledAlex Williamson
We were relying on msix_unset_vector_notifiers() to release all the vectors when we disable MSI-X, but this only happens when MSI-X is still enabled on the device. Perform further cleanup by releasing any remaining vectors listed as in-use after this call. This caused a leak of IRQ routes on hotplug depending on how the guest OS prepared the device for removal.

2013-12-06vfio-pci: Fix Nvidia MSI ACK through 0x88000 quirkAlex Williamson
When MSI is enabled on Nvidia GeForce cards the driver seems to acknowledge the interrupt by writing a 0xff byte to the MSI capability ID register using the PCI config space mirror at offset 0x88000 from BAR0. Without this, the device will only fire a single interrupt. VFIO handles the PCI capability ID/next registers as virtual w/o write support, so any write through config space is currently dropped. Add a check for this and allow the write through the BAR window. The registers are read-only anyway. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2013-12-06qemu-iotests: filter QEMU monitor \r\nStefan Hajnoczi
SMTP does not preserve newlines. This is normally not a problem if the email body uses DOS or UNIX newlines consistently. In 051.out we mix UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n). This patch filters the QEMU monitor output so the golden master file uses UNIX newlines exclusively. The result is that patches touching 051.out will apply cleanly without mangling newlines after this commit. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-12-06aio: make aio_poll(ctx, true) block with no fdsStefan Hajnoczi
This patch drops a special case where aio_poll(ctx, true) returns false instead of blocking if no file descriptors are waiting on I/O. Now it is possible to block in aio_poll() to wait for aio_notify(). This change eliminates busy waiting. bdrv_drain_all() used to rely on busy waiting to completed throttled I/O requests but this is no longer required so we can simplify aio_poll(). Note that aio_poll() still returns false when aio_notify() was used. In other words, stopping a blocking aio_poll() wait is not considered making progress. Adjust test-aio /aio/bh/callback-delete/one which assumed aio_poll(ctx, true) would immediately return false instead of blocking.
