2014-11-07spi: dw: Fix dynamic speed change.Thor Thayer
An IOCTL call that calls spi_setup() and then dw_spi_setup() will overwrite the persisted last transfer speed. On each transfer, the SPI speed is compared to the last transfer speed to determine if the clock divider registers need to be updated (did the speed change?). This bug was observed with the spidev driver using spi-config to update the max transfer speed. This fix: Don't overwrite the persisted last transaction clock speed when updating the SPI parameters in dw_spi_setup(). On the next transaction, the new speed won't match the persisted last speed and the hardware registers will be updated. On initialization, the persisted last transaction clock speed will be 0 but will be updated after the first SPI transaction. Move zeroed clock divider check into clock change test because chip->clk_div is zero on startup and would cause a divide-by-zero error. The calculation was wrong as well (can't support odd #).

Linville says: ==================== pull request: wireless 2014-11-06 Please pull this batch of fixes intended for the 3.18 stream... For the mac80211 bits, Johannes says: "This contains another small set of fixes for 3.18, these are all over the place and most of the bugs are old, one even dates back to the original mac80211 we merged into the kernel." For the iwlwifi bits, Emmanuel says: "I fix here two issues that are related to the firmware loading flow. A user reported that he couldn't load the driver because the rfkill line was pulled up while we were running the calibrations. This was happening while booting the system: systemd was restoring the "disable wifi settings" and that raised an RFKILL interrupt during the calibration. Our driver didn't handle that properly and this is now fixed." Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-07ARM: mvebu: use simple-card DT binding for audio on Armada 370 DBThomas Petazzoni
This commit modifies the Armada 370 and Armada 370 DB Device Tree descriptions to use the simple-card DT binding to describe the audio complex of the Armada 370 DB instead of a custom audio machine driver. To do so, it: - Adds the sound-dai-cells properties to the CS42L51 node, the audio controller node and the SPDIF in/out nodes. - Completely changes the description of the sound complex to use the "simple-audio-card" DT binding instead of the "marvell,a370db-audio" DT binding. - Fixes the indentation to properly use tabs instead of spaces.

2014-11-07ARM: mvebu: remove conflicting muxing on Armada 370 DBThomas Petazzoni
Back when audio was enabled, the muxing of some MPP pins was causing problems. However, since commit fea038ed55ae ("ARM: mvebu: Add proper pin muxing on the Armada 370 DB board"), those problematic MPP pins have been assigned a proper muxing for the Ethernet interfaces. This proper muxing is now conflicting with the hog pins muxing that had been added as part of 249f3822509b ("ARM: mvebu: add audio support to Armada 370 DB"). Therefore, this commit simply removes the hog pins muxing, which solves a warning a boot time due to the conflicting muxing requirements.

2014-11-06PCI/MSI: Add pci_msi_ignore_mask to prevent writes to MSI/MSI-X Mask BitsYijing Wang
MSI-X vector Mask Bits are in MSI-X Tables in PCI memory space. Xen PV guests can't write to those tables. MSI vector Mask Bits are in PCI configuration space. Xen PV guests can write to config space, but those writes are ignored. Commit 0e4ccb1505a9 ("PCI: Add x86_msi.msi_mask_irq() and msix_mask_irq()") added a way to override default_mask_msi_irqs() and default_mask_msix_irqs() so they can be no-ops in Xen guests, but this is more complicated than necessary. Add "pci_msi_ignore_mask" in the core PCI MSI code. If set, default_mask_msi_irqs() and default_mask_msix_irqs() return without doing anything. This is less flexible, but much simpler.

2014-11-06net/mlx5_core: Fix race in create EQEli Cohen
After the EQ is created, it can possibly generate interrupts and the interrupt handler is referencing eq->dev. It is therefore required to set eq->dev before calling request_irq() so if an event is generated before request_irq() returns, we will have a valid eq->dev field.

2014-11-07xfs: track bulkstat progress by aginoDave Chinner
The bulkstat main loop progress is tracked by the "lastino" variable, which is a full 64 bit inode. However, the loop actually works on agno/agino pairs, and so there's a significant disconnect between the rest of the loop and the main cursor. Convert this to use the agino, and pass the agino into the chunk formatting function and convert it too. This gets rid of the inconsistency in the loop processing, and finally makes it simple for us to skip inodes at any point in the loop simply by incrementing the agino cursor. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
2014-11-07xfs: bulkstat error handling is brokenDave Chinner
The error propagation is a horror - xfs_bulkstat() returns a rval variable which is only set if there are formatter errors. Any sort of btree walk error or corruption will cause the bulkstat walk to terminate but will not pass an error back to userspace. Worse is the fact that formatter errors will also be ignored if any inodes were correctly formatted into the user buffer. Hence bulkstat can fail badly yet still report success to userspace. This causes significant issues with xfsdump not dumping everything in the filesystem yet reporting success. It's not until a restore fails that there is any indication that the dump was bad and tha bulkstat failed. This patch now triggers xfsdump to fail with bulkstat errors rather than silently missing files in the dump. This now causes bulkstat to fail when the lastino cookie does not fall inside an existing inode chunk. The pre-3.17 code tolerated that error by allowing the code to move to the next inode chunk as the agino target is guaranteed to fall into the next btree record. With the fixes up to this point in the series, xfsdump now passes on the troublesome filesystem image that exposes all these bugs. cc: <stable@vger.kernel.org> Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com>

2014-11-07xfs: bulkstat chunk-formatter has issuesDave Chinner
The loop construct has issues: - clustidx is completely unused, so remove it. - the loop tries to be smart by terminating when the "freecount" tells it that all inodes are free. Just drop it as in most cases we have to scan all inodes in the chunk anyway. - move the "user buffer left" condition check to the only point where we consume space int eh user buffer. - move the initialisation of agino out of the loop, leaving just a simple loop control logic using the clusteridx. Also, double handling of the user buffer variables leads to problems tracking the current state - use the cursor variables directly rather than keeping local copies and then having to update the cursor before returning. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
2014-11-07xfs: bulkstat chunk formatting cursor is brokenDave Chinner
The xfs_bulkstat_agichunk formatting cursor takes buffer values from the main loop and passes them via the structure to the chunk formatter, and the writes the changed values back into the main loop local variables. Unfortunately, this complex dance is full of corner cases that aren't handled correctly. The biggest problem is that it is double handling the information in both the main loop and the chunk formatting function, leading to inconsistent updates and endless loops where progress is not made. To fix this, push the struct xfs_bulkstat_agichunk outwards to be the primary holder of user buffer information. this removes the double handling in the main loop. Also, pass the last inode processed by the chunk formatter as a separate parameter as it purely an output variable and is not related to the user buffer consumption cursor. Finally, the chunk formatting code is not shared by anyone, so make it local to xfs_itable.c. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
2014-11-07xfs: bulkstat btree walk doesn't terminateDave Chinner
The bulkstat code has several different ways of detecting the end of an AG when doing a walk. They are not consistently detected, and the code that checks for the end of AG conditions is not consistently coded. Hence the are conditions where the walk code can get stuck in an endless loop making no progress and not triggering any termination conditions. Convert all the "tmp/i" status return codes from btree operations to a common name (stat) and apply end-of-ag detection to these operations consistently. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>

2014-11-06perf evsel: Do not call pevent_free_format when deleting tracepointJiri Olsa
The libtraceevent library's main handle 'struct pevent' holds pointers of every event that was added to it via functions: pevent_parse_format pevent_parse_event We can't release struct event_format (call pevent_free_format) separately, because that breaks that pointers array mentioned above and another add_event call could end up with segfault. All added events are released within the handle cleanup in pevent_free.
