2010-02-11drm/vmwgfx: Update the user-space interface.Thomas Hellstrom
When time-based throttling is implemented, we need to bump minor. When the old way of detecting scanout is removed, we need to bump major.

2010-02-10sky2: receive checksum refactoringstephen hemminger
Break the largish case for handling receive checksum into a separate function, and if there is a problem use dev_XXX routines to show which hardware is the problem. Turn one corner case into a BUG(). This only happens if the driver is expecting one behavior but the chip does the old behavior; only ever saw this when bringing up a new chip type and driver was buggy.

2010-02-10drm/i915: Fix crash while aborting hibernationRafael J. Wysocki
Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915) introduced the problem that if s2disk hibernation is aborted, the system will crash, because i915_pm_freeze() does nothing, while it should at least reverse some operations carried out by i915_suspend(). Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

2010-02-10drm/i915: untangle page flip completionJesse Barnes
When a new page flip is requested, we need to both queue an unpin for the current framebuffer, and also increment the flip pending count on the newly submitted buffer. At flip finish time, we need to unpin the old fb and decrement the flip pending count on the new buffer. The old code was conflating the two, and led to hangs when new direct rendered apps were started, replacing the existing frame buffer. This patch splits out the buffers and prevents the hangs.

2010-02-10drm/i915: Increase fb alignment to 64kChris Wilson
An untiled framebuffer must be aligned to 64k. This is normally handled by intel_pin_and_fence_fb_obj(), but the intelfb_create() likes to be different and do the pinning itself. However, it aligns the buffer object incorrectly for pre-i965 chipsets causing a PGTBL_ERR when it is installed onto the output.

2010-02-10drm/i915: Update write_domains on active list after flush.Daniel Vetter
Before changing the status of a buffer with a pending write we will await upon a new flush for that buffer. So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson <chris@chris-wilson.co.uk>, forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

2010-02-10RDMA/cm: Revert association of an RDMA device when binding to loopbackSean Hefty
Revert the following change from commit 6f8372b6 ("RDMA/cm: fix loopback address support") The defined behavior of rdma_bind_addr is to associate an RDMA device with an rdma_cm_id, as long as the user specified a non- zero address. (ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdma_bind_addr, no device is associated with the rdma_cm_id. Fix this. It turns out that important apps such as Open MPI depend on rdma_bind_addr() NOT associating any RDMA device when binding to a loopback address. Open MPI is being updated to deal with this, but at least until a new Open MPI release is available, maintain the previous behavior: allow rdma_bind_addr() to succeed, but do not bind to a device.

2010-02-10via-velocity: Fix races on shared interruptsSimon Kagstrom
This patch fixes two potential races in the velocity driver: * Move the ACK and error handler to the interrupt handler. This fixes a potential race with shared interrupts when the other device interrupts before the NAPI poll handler has finished. As the velocity driver hasn't acked it's own interrupt, it will then steal the interrupt from the other device. * Use spin_lock_irqsave in velocity_poll. In the current code, the interrupt handler will deadlock if e.g., the NAPI poll handler is executing when an interrupt (for another device) comes in since it tries to take the already held lock. Also unlock the spinlock only after enabling the interrupt in velocity_poll. The error path is moved to the interrupt handler since this is where the ISR is checked now.
