At boot you will see the following message: m25p80 spi1.0: found s25fl064k, expected w25q64 This is because the JEDEC ID for this chip is the same as s25fl064k.

* ARM: dts: dra7: Add updated operating-points-v2 table for cpuDave Gerlach2017-03-232-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | After the ti-cpufreq driver has been added, we can now drop the operating-points table present in dra7.dtsi for the cpu and add an operating-points-v2 table with all OPPs available for all silicon revisions. Also add necessary data for use by ti-cpufreq to selectively enable the appropriate OPPs at runtime as part of the operating-points table. As we now need to define voltage ranges for each OPP, we define the minimum and maximum voltage to match the ranges possible for AVS class0 voltage as defined by the DRA7/AM57 Data Manual, with the exception of using a range for OPP_OD based on historical data to ensure that SoCs from older lots still continue to boot, even though more optimal voltages are now the standard. Once an AVS Class0 driver is in place it will be possible for these OPP voltages to be adjusted to any voltage within the provided range. Information from SPRS953, Revised December 2015.

| | | | | | | | | | | | | | The operatings-points-v2 table for am4372 was merged before any user of it was present in the kernel and before the binding had been finalized. The new ti-cpufreq driver and binding expects the platform specific properties to be part of the operating-points-v2 table rather than the cpu node so let's move them there as the only user is the ti-cpufreq driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The underlying nlmsg_multicast() already sets sk->sk_err for us to notify socket overruns, so we should not do anything with this return value. So we just call nfnetlink_set_err() if: 1) We fail to allocate the netlink message. or 2) We don't have enough space in the netlink message to place attributes, which means that we likely need to allocate a larger message. Before this patch, the internal ESRCH netlink error code was propagated to userspace, which is quite misleading. Netlink semantics mandate that listeners just hit ENOBUFS if the socket buffer overruns.

The code now checks to see if the adapter needs to be brought out of reset (where as before it was doing an IDM write to bring it out of reset regardless of whether it was in reset or not). Also, removed unnecessary usleeps (as there is already a read present to flush the IDM writes).

Unfortunately subsequent commit f16f1df65f1c "xen-netback: protect resource cleaning on XenBus disconnect" then wrapped this call to vfree() in a spin lock, leading to a BUG due to incorrect context.

Paolo fixes the driver so that you can actually update the RSS key value via ethtool. Alex fixes an issue on architectures that have a cache line size larger than 64 Bytes, where the amount of headroom for the frame starts shrinking. To take this into account, Alex adds one small check so that we compare the max_frame to the amount of actual data we can store, so we will automatically enable 3K receive buffers as soon as the maximum frame size we can handle drops below the standard Ethernet MTU. ==================== Signed-off-by: David S.

| | * | ixgbe: Limit use of 2K buffers on architectures with 256B or larger cache linesAlexander Duyck2017-03-032-2/+3

The size of skb_shared_info on a system with a 64B L1 cache line size is 320. This increases to 384 with a 128B cache line, and 512 with a 256B cache line. In addition the NET_SKB_PAD value increases as well consistent with the cache line size. As a result when we get to a 256B cache line as seen on the s390 we end up 768 bytes used by padding and shared info leaving us with only 1280 bytes to use for data storage. On architectures such as this we should default to using 3K Rx buffers out of a 8K page instead of trying to do 1.5K buffers out of a 4K page. To take all of this into account I have added one small check so that we compare the max_frame to the amount of actual data we can store. This was already occurring for igb, but I had overlooked it for ixgbe as it doesn't have strict limits for 82599 once we enable jumbo frames. By adding this check we will automatically enable 3K Rx buffers as soon as the maximum frame size we can handle drops below the standard Ethernet MTU. I also went through and fixed one small typo that I found where I had left an IGB in a variable name due to a copy/paste error.
