2019-03-26i40e: fix i40e_ptp_adjtime when given a negative deltaJacob Keller
Commit 0ac30ce43323 ("i40e: fix up 32 bit timespec references", 2017-07-26) claims to be cleaning up references to 32-bit timespecs. The actual contents of the commit make no sense, as it converts a call to timespec64_add into timespec64_add_ns. This would seem ok, if (a) the change was documented in the commit message, and (b) timespec64_add_ns supported negative numbers. timespec64_add_ns doesn't work with signed deltas, because the implementation is based around iter_div_u64_rem. This change resulted in a regression where i40e_ptp_adjtime would interpret small negative adjustments as large positive additions, resulting in incorrect behavior. This commit doesn't appear to fix anything, is not well explained, and introduces a bug, so lets just revert it.

2019-03-26ice: Audit hotpath structures with paholeBrett Creeley
Currently the ice_q_vector structure and ice_ring_container structure are taking up more space than necessary due to cache alignment holes and unnecessary variables respectively. This is not helping the driver's performance. The following fixes were done to improve cache alignment, reduce wasted space, and increase performance. 1. Remove the ice_latency_range enum as it is unused. 2. Remove the latency_range variable in the ice_ring_container structure. 3. Change the size of the itr_idx in the ice_ring_container structure from an int to an u16. This reduced the size of ice_ring_container structure to 32 Bytes so it has no holes or padding. 4. Re-arrange the ice_q_vector structure using pahole to align members as best as possible in regards to 64 Byte cache line size.

This patch updates the qca8k's binding to document to the approach for using the internal mdio-bus of the supported qca8k switches. Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

In the example, the phy at phy@0 is clashing with the switch0@0 at the same address. Usually, the switches are accessible through pseudo PHYs which in case of the qca8k are located at 0x10 - 0x18.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-03-25 This series contains updates to the ice driver only. Victor updates the ice driver to be able to update the VSI queue configuration dynamically, by providing the ability to increase or decrease the VSI's number of queues. Michal fixes an issue when the VM starts or the VF driver is reloaded, the VLAN switch rule was lost (i.e. not added), so ensure it gets added in these cases. Brett updates the driver to support link events over the admin receive queue, instead of polling link events. Maciej refactors the code a bit to introduce a new function to fetch the receiver buffer and do the DMA synchronization to reduce the code duplication. Also added ice_can_reuse_rx_page() to verify whether the page can be reused so that in the future, we can use this check elsewhere in the driver. Additional driver optimizations so that we can drop the ice_pull_tail() altogether. Added support for bulk updates of refcount instead of doing it one by one. Refactored the page counting and buffer recycling so that we can use this code to clean up receive buffers when there is no skb allocated, like XDP. Added DMA_ATTR_WEAK_ORDERING and DMA_ATTR_SKIP_CPU_SYNC attributes to the DMA API during the mapping operations on the receive side, so that nonx86 platforms will be able to sync with what is being used (2k buffers) instead of the entire page. Dave fixes the driver to perform the most intrusive of the resets requested and clear the other request bits so that we do not end up with repeated reset, after reset. Bruce adds a iterator macro to clean up several for() loops. Chinh modifies the packet flags to be more generic so that they can be used for both receive and transmit. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

On an Acer Predator Helios 500 (Ryzen version), the laptop's speakers don't work out of the box. The problem can be worked around with hdajackretask, remapping the "Black Headphone, Right side" pin (0x21) to the Internal speaker. This patch adds a quirk to change this mapping by default.

2019-03-26xfs: serialize unaligned dio writes against all other dio writesBrian Foster
XFS applies more strict serialization constraints to unaligned direct writes to accommodate things like direct I/O layer zeroing, unwritten extent conversion, etc. Unaligned submissions acquire the exclusive iolock and wait for in-flight dio to complete to ensure multiple submissions do not race on the same block and cause data corruption. This generally works in the case of an aligned dio followed by an unaligned dio, but the serialization is lost if I/Os occur in the opposite order. If an unaligned write is submitted first and immediately followed by an overlapping, aligned write, the latter submits without the typical unaligned serialization barriers because there is no indication of an unaligned dio still in-flight. This can lead to unpredictable results. To provide proper unaligned dio serialization, require that such direct writes are always the only dio allowed in-flight at one time for a particular inode. We already acquire the exclusive iolock and drain pending dio before submitting the unaligned dio. Wait once more after the dio submission to hold the iolock across the I/O and prevent further submissions until the unaligned I/O completes. This is heavy handed, but consistent with the current pre-submission serialization for unaligned direct writes.
