Now that all of the in-tree drivers have been converted to portable I/O accessors, we can kill off the legacy ones with extreme prejudice. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-01-10Merge branch 'master' into for-linus-mergedAlex Elder
This merge pulls the XFS master branch into the latest Linus master. This results in a merge conflict whose best fix is not obvious. I manually fixed the conflict, in "fs/xfs/xfs_iget.c". Dave Chinner had done work that resulted in RCU freeing of inodes separate from what Nick Piggin had done, and their results differed slightly in xfs_inode_free(). The fix updates Nick's call_rcu() with the use of VFS_I(), while incorporating needed updates to some XFS inode fields implemented in Dave's series. Dave's RCU callback function has also been removed. Signed-off-by: Alex Elder <aelder@sgi.com>
2011-01-11video: matroxfb: Correct video option in comments and kernel config help.Vicente Jiménez
Configuring the kernel I found that the Matrox frame buffer help has a different option than the one in the docs (Documentation/fb/matroxfb.txt). I decided to check the source code to see what is the correct option. drivers/video/matrox/matroxfb_base.c has a lot of comments that sugests that the video option is "matrox". However in line 2452 of this same file you have: fb_get_options("matroxfb", &option) video=matroxfb:XXX is the correct video option not video=matrox:XXX.

2011-01-11fbdev: sh_mobile_hdmi: framebuffer notifiers have to be registeredGuennadi Liakhovetski
A previous patch added a framebuffer notifier to sh_mobile_hdmi.c, but did not register it with the framebuffer core. This patch adds such a registration and moves the notifier block into dynamically allocated per-device private data.

2011-01-11fbdev: sh_mobile_hdmi: add command line option to use the preferred EDID modeGuennadi Liakhovetski
Currently, if no command-line option is specified, the sh_mobile_hdmi will use the default 720p video mode. If a command line option of the form "video=sh_mobile_lcdc:<width>x<height>@<refresh>" is provided, the driver will look for that mode among those, available in the monitor EDID. This patch adds the ability to request the driver to use monitor's preferred mode by specifying 0 as width and hight in the above string. If that mode is not supported by the system, the driver will continue scanning through EDID modes, until it finds a suitable one.

2011-01-10IB/qib: Fix refcount leak in lkey/rkey validationMike Marciniszyn
The mr optimization introduced a reference count leak on an exception test. The lock/refcount manipulation is moved down and the problematic exception test now calls bail to insure that the lock is released. Additional fixes as suggested by Ralph Campbell <ralph.campbell@qlogic.org>: - reduce lock scope of dma regions - use explicit values on returns vs. automatic ret value Signed-off-by: Mike Marciniszyn <mike.marciniszyn@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2011-01-10IB/qib: Unnecessary delayed completions on RC connectionMike Marciniszyn
Currently on receipt of a response message (ACKs, RDMA Response, Atomic Responses etc.) if the SDMA completion counter is not advanced the driver delays the completion of the WQE. In most cases this is overly pessimistic as the response (ACK) to a previously transmitted send implies that the send is complete. Ensure that SDMA queue is progressed appropriately before determining if a send has delayed completions.

2011-01-10IB/qib: Issue pre-emptive NAKs on eager buffer overflowMike Marciniszyn
Under congestion resulting in eager buffer overflow attempt to send pre-emptive NAKs if header queue entries with TID errors are generated and a valid header is present. This prevents long timeouts and flow restarts if a trailing set of packets are dropped due to eager overflows. Pre-emptive NAKs are currently only supported for RDMA writes.

2011-01-10IB/qib: RDMA lkey/rkey validation is inefficient for large MRsMike Marciniszyn
The current code loops during rkey/lkey validiation to isolate the MR for the RDMA, which is expensive when the current operation is inside a very large memory region. This fix optimizes rkey/lkey validation routines for user memory regions and fast memory regions. The MR entry can be isolated by shifts/mods instead of looping. The existing loop is preserved for phys memory regions for now. Signed-off-by: Mike Marciniszyn <mike.marciniszyn@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2011-01-10IB/qib: Change receive queue/QPN selectionMike Marciniszyn
The basic idea is that on SusieQ, the difficult part of mapping QPN to context is handled by the mapping registers so the generic QPN allocation doesn't need to worry about chip specifics. For Monty and Linda, there is no mapping table so the qpt->mask (same as dd->qpn_mask), is used to see if the QPN to context falls within [zero..dd->n_krcv_queues).

2011-01-10IB/qib: Fix interrupt mitigationMike Marciniszyn
For SusieQ we need to write to the interrupt timer register before updating the header queue head with interrupt count. This is to ensure that the timer is enabled properly and a receive available interrupt is delivered. Otherwise this interrupt can be lost if the receiver header/eager queues are full before the timer is enabled.

2011-01-10IB/qib: Clear WAIT_SEND flags when setting QP to error stateMike Marciniszyn
If these flags are set when the QP is transitioned to the error state, it will wait until the flags are cleared, which may never happen if the error transition is due to a link going down. Signed-off-by: Mike Marciniszyn <mike.marciniszyn@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2011-01-10IB/qib: Fix context allocation with multiple HCAsMike Marciniszyn

2011-01-10IB/qib: Fix multi-Florida HCA host panic on rebootMike Marciniszyn

2011-01-10IB/qib: Handle transitions from ACTIVE_DEFERRED to ACTIVE betterMike Marciniszyn
When the link transitions from ACTIVE_DEFERRED to ACTIVE, the driver only sees the ACTIVE state. With this change, it will check whether the state was already ACTIVE and if so, it will not generated IB events and will not clear symbol error counts.

2011-01-10IB/qib: UD send with immediate receive completion has wrong sizeMike Marciniszyn
The code to generate receive completion entries for UD send with immediate contains the wrong payload length. This is because when the code to compute the payload size was moved, the value of hdrsize didn't get moved too. The fix is to update tlen directly.

2011-01-10IB/qib: Set port physical state even if other fields are invalidMike Marciniszyn
The IBTA vol. 1 release 1.2.1 spec. says: C14-24.2.1: If PortInfo:Portstate=Down, then a SubnSet(PortInfo) shall make any changes it specifies to PortInfo:PortPhysicalState; any other result is vendor-dependent. The patch changes the error handling so that the reply says there are invalid fields but still attempts to set fields that are in range including PortInfo:PortPhysicalState.

2011-01-10IB/qib: Generate completion callback on errorsMike Marciniszyn

2011-01-10IB/mlx4: Don't call dma_free_coherent() with irqs disabledVladimir Sokolovsky
mlx4_ib_free_cq_buf() should not be called under spin_lock_irq() since it calls dma_free_coherent(), which needs irqs enabled. Fix this by deferring the free to outside the locked region.

The kernel warning message added in commit 58d74bb1d9f7 ("mlx4_core: Workaround firmware bug in query dev cap") about mlx4 reporting the wrong number of "blue flame registers" doesn't really help anyone, since the firmware bug is known and fixed and the bug is pretty much harmless to users.

Re-initializing the wait object in rdma_init()/rdma_fini() causes a timing window which can lead to a deadlock during close.
