This pushes qed [and as result, all qed* drivers] into using 8.20.0.0 firmware. The changes are mostly contained in qed with minor changes to qedi due to some HSI changes. Content-wise, the firmware contains fixes to various issues exposed since the release of the previous firmware, including: - Corrects iSCSI fast retransmit when data digest is enabled. - Stop draining packets when receiving several consecutive PFCs. - Prevent possible assertion when consecutively opening/closing many connections. - Prevent possible assertion due to too long BDQ fetch time.

2017-05-18drivers: char: mem: Check for address space wraparound with mmap()Julius Werner
/dev/mem currently allows mmap() mappings that wrap around the end of the physical address space, which should probably be illegal. It circumvents the existing STRICT_DEVMEM permission check because the loop immediately terminates (as the start address is already higher than the end address). On the x86_64 architecture it will then cause a panic (from the BUG(start >= end) in arch/x86/mm/pat.c:reserve_memtype()). This patch adds an explicit check to make sure offset + size will not wrap around in the physical address type.

We can't assume that we are always in loopback mode if rx and tx clock have the same clock source. If we want to use HDLC busmode we also have the same clock source but we are not in loopback mode. So move the setting of the baudrate generator after the check for property for the loopback mode.

2017-05-18udp: make *udp*_queue_rcv_skb() functions staticPaolo Abeni
Since the udp memory accounting refactor, we don't need any more to export the *udp*_queue_rcv_skb(). Make them static and fix a couple of sparse warnings: net/ipv4/udp.c:1615:5: warning: symbol 'udp_queue_rcv_skb' was not declared. Should it be static? net/ipv6/udp.c:572:5: warning: symbol 'udpv6_queue_rcv_skb' was not declared. Should it be static?
