NET: stmmac: align DMA stuff to largest cache line length

2018-08-06T14:24:41Z

[ Upstream commit 9939a46d90c6c76f4533d534dbadfa7b39dc6acc ] As for today STMMAC_ALIGN macro (which is used to align DMA stuff) relies on L1 line length (L1_CACHE_BYTES). This isn't correct in case of system with several cache levels which might have L1 cache line length smaller than L2 line. This can lead to sharing one cache line between DMA buffer and other data, so we can lose this data while invalidate DMA buffer before DMA transaction. Fix that by using SMP_CACHE_BYTES instead of L1_CACHE_BYTES for aligning. Signed-off-by: Eugeniy Paltsev Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

xen-netfront: wait xenbus state change when load module manually

2018-08-06T14:24:40Z

[ Upstream commit 822fb18a82abaf4ee7058793d95d340f5dab7bfc ] When loading module manually, after call xenbus_switch_state to initializes the state of the netfront device, the driver state did not change so fast that may lead no dev created in latest kernel. This patch adds wait to make sure xenbus knows the driver is not in closed/unknown state. Current state: [vm]# ethtool eth0 Settings for eth0: Link detected: yes [vm]# modprobe -r xen_netfront [vm]# modprobe xen_netfront [vm]# ethtool eth0 Settings for eth0: Cannot get device settings: No such device Cannot get wake-on-lan settings: No such device Cannot get message level: No such device Cannot get link status: No such device No data available With the patch installed.

net: lan78xx: fix rx handling before first packet is send

[ Upstream commit 136f55f660192ce04af091642efc75d85e017364 ] As long the bh tasklet isn't scheduled once, no packet from the rx path will be handled. Since the tx path also schedule the same tasklet this situation only persits until the first packet transmission. So fix this issue by scheduling the tasklet after link reset.

rsi: Fix 'invalid vdd' warning in mmc

2018-08-06T14:24:38Z

[ Upstream commit 78e450719c702784e42af6da912d3692fd3da0cb ] While performing cleanup, driver is messing with card->ocr value by not masking rocr against ocr_avail. Below panic is observed with some of the SDIO host controllers due to this. Issue is resolved by reverting incorrect modifications to vdd.

brcmfmac: Add support for bcm43364 wireless chipset

2018-08-06T14:24:36Z

[ Upstream commit 9c4a121e82634aa000a702c98cd6f05b27d6e186 ] Add support for the BCM43364 chipset via an SDIO interface, as used in e.g. the Murata 1FX module. The BCM43364 uses the same firmware as the BCM43430 (which is already included), the only difference is the omission of Bluetooth. However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place triggers the brcmfmac driver to load, and then correctly use the firmware file 'brcmfmac43430-sdio.bin'.
