2016-04-15rtl8xxxu: Implment rtl8192e_set_tx_power()Jes Sorensen
8192eu is a 2T part, so setting TX power for path A only, as done by rtl8723bu_set_tx_power() is not sufficient. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-04-15rtl8xxxu: Do not init FPGA0_TX_INFO on 8192euJes Sorensen

2016-04-15rtl8xxxu: Do not set REG_PBP on 8192euJes Sorensen
The vendor driver does not set REG_PBP on 8192eu. Whether this is due to the device not supporting it or simply an oversight in the vendor driver is not clear. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-04-15mwifiex: factor out mwifiex_cancel_pending_scan_cmdAndreas Fenkart
Releasing the scan_pending lock in mwifiex_check_next_scan_command introduces a short window where pending scan commands can be removed or added before removing them all in mwifiex_cancel_pending_scan_cmd. I think this is safe, since the worst thing to happen is that a pending scan cmd is removed by the command handler. Adding new scan commands is not possible while one is pending, see scan_processing flag. Since all commands are removed from the queue anyway, we don't care if some commands are removed by a different code path earlier, the final state remains the same. I assume, that the critical section needed for the check has been extended over clearing the pending scan queue out of convenience. The lock was already held and releasing it and grab it again was just more work. It doesn't seem to be necessary because of concurrency.

2016-04-15devcoredump: add scatterlist supportAviya Erenfeld
Add scatterlist support (dev_coredumpsg) to allow drivers to avoid vmalloc() like dev_coredumpm(), while also avoiding the module reference that the latter function requires. This internally uses dev_coredumpm() with function inside the devcoredump module, requiring removing the const (which touches the driver using it.)

2016-04-15cxgb4: Set VPD size so we can read both VPD structuresHariprasad Shenai
Chelsio adapters have two VPD structures stored in the VPD: - offset 0x000: an abbreviated VPD, and - offset 0x400: the complete VPD. After 104daa71b396 ("PCI: Determine actual VPD size on first access"), the PCI core computes the valid VPD size by parsing the VPD starting at offset 0x0. That size only includes the abbreviated VPD structure, so reads of the complete VPD at 0x400 fail. Explicitly set the VPD size with pci_set_vpd_size() so the driver can read both VPD structures.

2016-04-14tun: use per cpu variables for stats accountingPaolo Abeni
Currently the tun device accounting uses dev->stats without applying any kind of protection, regardless that accounting happens in preemptible process context. This patch move the tun stats to a per cpu data structure, and protect the updates with u64_stats_update_begin()/u64_stats_update_end() or this_cpu_inc according to the stat type.

2016-04-14cdc_mbim: apply "NDP to end" quirk to all Huawei devicesBjørn Mork
We now have a positive report of another Huawei device needing this quirk: The ME906s-158 (12d1:15c1). This is an m.2 form factor modem with no obvious relationship to the E3372 (12d1:157d) we already have a quirk entry for. This is reason enough to believe the quirk might be necessary for any number of current and future Huawei devices. Applying the quirk to all Huawei devices, since it is crucial to any device affected by the firmware bug, while the impact on non-affected devices is negligible.

That allows faster processing on firmware side avoiding unused time in between EMADs. Measured speedup is ~30% for shared occupancy snapshot operation.

As explained in commit ff6551ec0c27 ("mlxsw: spectrum: Correctly configure headroom size") control packets are directed to priority group buffer 9 (PG9) in the ports' headroom buffers. Since we don't want to drop control packets in case they can't be admitted to the switch's shared buffer we bind PG9 to a different ingress pool from the one used by all other PGs. Unlike other PGs, we currently don't expose the binding between PG9 to a pool and leave it fixed.
