2015-08-25brcmfmac: block the correct flowring when backup queue overflowFranky Lin
brcmf_flowring_block blocks the last active flowring under the same interface instead of the one provided by caller. This could lead to a dead lock of netif stop if there are more than one flowring under the interface and the traffic is high enough so brcmf_flowring_enqueue can not unblock the ring right away.

2015-08-25batman-adv: Fix gw_bandwidth calculation on 32 bit systemsSven Eckelmann
The TVLV for the gw_bandwidth stores everything as u32. But the gw_bandwidth reads the signed long which limits the maximum value to (2 ** 31 - 1) on systems with 4 byte long. Also the input value is always converted from either Mibit/s or Kibit/s to 100Kibit/s. This reduces the values even further when the user sets it via the default unit Kibit/s. It may even cause an integer overflow and end up with a value the user never intended. Instead read the values as u64, check for possible overflows, do the unit adjustments and then reduce the size to u32.
