2017-02-16btmrvl: set irq_bt to -1 when failed to parse itJeffy Chen
The irq_of_parse_and_map will return 0 as a invalid irq. Set irq_bt to -1 in this case, so that the btmrvl resume/suspend code would not try to enable/disable it.

It's much the same as what we did for mwifiex in: b9da4d2 mwifiex: avoid double-disable_irq() race "We have a race where the wakeup IRQ might be in flight while we're calling mwifiex_disable_wake() from resume().

2017-02-16Bluetooth: btusb: Configure Marvell to use one of the pins for oob wakeupRajat Jain
The Marvell devices may have many gpio pins, and hence for wakeup on these out-of-band pins, the chip needs to be told which pin is to be used for wakeup, using an hci command. Thus, we read the pin number etc from the device tree node and send a command to the chip.

2017-02-16Bluetooth: btusb: Add out-of-band wakeup supportRajat Jain
Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that can be connected to a gpio on the CPU side, and can be used to wakeup the host out-of-band. This can be useful in situations where the in-band wakeup is not possible or not preferable (e.g. the in-band wakeup may require the USB host controller to remain active, and hence consuming more system power during system sleep). The oob gpio interrupt to be used for wakeup on the CPU side, is read from the device tree node, (using standard interrupt descriptors). A devcie tree binding document is also added for the driver. The compatible string is in compliance with Documentation/devicetree/bindings/usb/usb-device.txt Signed-off-by: Rajat Jain <rajatja@google.com> Reviewed-by: Brian Norris <briannorris@chromium.org> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Currently, the IPID and Syndrome are printed on the same line as the Address. There are cases when we can have a valid Syndrome but not a valid Address. For example, the MCA_SYND register can be used to hold more detailed error info that the hardware folks can use. It's not just DRAM ECC syndromes. There are some error types that aren't related to memory that may have valid syndromes, like some errors related to links in the Data Fabric, etc. In these cases, the IPID and Syndrome are not printed at the same log level as the rest of the stanza, so users won't see them on the console.

2017-02-16ixgbe: Don't bother clearing buffer memory for descriptor ringsAlexander Duyck
This patch makes it so that we don't need to bother with clearing the memory out for the descriptor rings. The general idea is to only free buffers associated with buffers in use which are located between the next_to_clean and next_to_use or next_to_alloc values. Everything outside of those regions can be safely ignored since they should have no buffers associated with them. The advantage to doing things this way is that is should speed up bring-up and tear-down of the rings. Specifically we can avoid the 512 or more cycles required to memset the rings in tear-down. In the bring-up phase we then clear the memory as a part of initialization. The general idea is that the clearing in initialization can act as a prefetch of sorts for the buffer info structures so they are in the local CPU when we go to populate them. This should help to improve overall time needed to perform a suspend/resume.

2017-02-16ixgbe: Add support for build_skbAlexander Duyck
This patch adds build_skb support to the Rx path. There are several advantages to this change. 1. It avoids the memcpy and skb->head allocation for small packets which improves performance by about 5% in my tests. 2. It avoids the memcpy, skb->head allocation, and eth_get_headlen for larger packets improving performance by about 10% in my tests. 3. For VXLAN packets it allows the full header to be in skb->data which improves the performance by as much as 30% in some of my tests.

2017-02-16ixgbe: Add private flag to control buffer modeAlexander Duyck
Since there are potential drawbacks to the new Rx allocation approach I thought it best to add a "chicken bit" so that we can turn the feature off if in the event that a problem is found. It also provides a means of validating the legacy Rx path in the event that we are forced to fall back. At some point in the future when we are convinced we don't need it anymore we might be able to drop the legacy-rx flag.

This change makes it so that we use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed.

2017-02-16ixgbe: Make use of order 1 pages and 3K buffers independent of FCoEAlexander Duyck
In order to support build_skb with jumbo frames it will be necessary to use 3K buffers for the Rx path with 8K pages backing them. This is needed on architectures that implement 4K pages because we can't support 2K buffers plus padding in a 4K page. In the case of systems that support page sizes larger than 4K the 3K attribute will only be applied to FCoE as we can fall back to using just 2K buffers and adding the padding.

By enabling both of these for the Rx path we are able to see performance improvements on architectures that implement either one due to the fact that page mapping and unmapping only has to sync what is actually being used instead of the entire buffer. In addition by enabling the weak ordering attribute enables a performance improvement for architectures that can associate a memory ordering with a DMA buffer such as Sparc.

2017-02-15net: stmmac: use SPEED_UNKNOWN/DUPLEX_UNKNOWNLABBE Corentin
It is better to use DUPLEX_UNKNOWN instead of just "-1". Using 0 for an invalid speed is bad since 0 is a valid value for speed. So this patch replace 0 by SPEED_UNKNOWN.

2017-02-15net: xilinx_emaclite: fix freezes due to unordered I/OAnssi Hannula
The xilinx_emaclite uses __raw_writel and __raw_readl for register accesses. Those functions do not imply any kind of memory barriers and they may be reordered. The driver does not seem to take that into account, though, and the driver does not satisfy the ordering requirements of the hardware. For clear examples, see xemaclite_mdio_write() and xemaclite_mdio_read() which try to set MDIO address before initiating the transaction. I'm seeing system freezes with the driver with GCC 5.4 and current Linux kernels on Zynq-7000 SoC immediately when trying to use the interface. In commit 123c1407af87 ("net: emaclite: Do not use microblaze and ppc IO functions") the driver was switched from non-generic in_be32/out_be32 (memory barriers, big endian) to __raw_readl/__raw_writel (no memory barriers, native endian), so apparently the device follows system endianness and the driver was originally written with the assumption of memory barriers. Rather than try to hunt for each case of missing barrier, just switch the driver to use iowrite32/ioread32/iowrite32be/ioread32be depending on endianness instead. Tested on little-endian Zynq-7000 ARM SoC FPGA.
