git://xenbits.xen.org/people/sstabellini/linux-pvhvm * 'v2.6.36-rc6-urgent-fixes' of git://xenbits.xen.org/people/sstabellini/linux-pvhvm: xen: do not initialize PV timers on HVM if !xen_have_vector_callback xen: do not set xenstored_ready before xenbus_probe on hvm
2010-10-05xen: do not set xenstored_ready before xenbus_probe on hvmStefano Stabellini
Register_xenstore_notifier should guarantee that the caller gets notified even if xenstore is already up. Therefore we revert "do not notify callers from register_xenstore_notifier" and set xenstored_read at the right time for PV on HVM guests too. In fact in case of PV on HVM guests xenstored is ready only after the platform pci driver has completed the initialization, so do not set xenstored_ready before the call to xenbus_probe(). This patch fixes a shutdown_event watcher registration bug that causes "xm shutdown" not to work properly.

2010-10-03drm/i915: Use pipe state to tell when pipe is offKeith Packard
Instead of waiting for the display line value to settle, we can simply wait for the pipe configuration register 'state' bit to turn off. Contrarywise, disabling the plane will not cause the display line value to stop changing, so instead we wait for the vblank interrupt bit to get set. And, we only do this when we're not about to wait for the pipe to turn off. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-10-01drm/gem: handlecount isn't really a kref so don't make it one.Dave Airlie
There were lots of places being inconsistent since handle count looked like a kref but it really wasn't. Fix this my just making handle count an atomic on the object, and have it increase the normal object kref. Now i915/radeon/nouveau drivers can drop the normal reference on userspace object creation, and have the handle hold it. This patch fixes a memory leak or corruption on unload, because the driver had no way of knowing if a handle had been actually added for this object, and the fbcon object needed to know this to clean itself up properly.
