2014-09-30bcma: register bcma as device tree driverHauke Mehrtens
This driver is used by the bcm53xx ARM SoC code. Now it is possible to give the address of the chipcommon core in device tree and bcma will search for all the other cores.

2014-09-30ARM: 8179/1: kprobes-test: Fix compile error "bad immediate value for offset"Jon Medhurst
When compiling kprobes-test-arm.c the following error has been observed /tmp/ccoT403o.s:21439: Error: bad immediate value for offset (4168) This is caused by the compiler spilling it's literal pool too far away from the site which is trying to reference it with a PC relative load. This arises because the compiler is underestimating the size of the inline assembler code present, which apparently it approximates as 4 bytes per line or instruction. We fix this problem by moving the operations which generate more than 4 bytes out of the text section. Specifically, moving the .ascii directives to the .rodata section.

2014-09-30bonding: make global bonding stats more reliableAndy Gospodarek
As the code stands today, bonding stats are based simply on the stats from the member interfaces. If a member was to be removed from a bond, the stats would instantly drop. This would be confusing to an admin would would suddonly see interface stats drop while traffic is still flowing. In addition to preventing the stats drops mentioned above, new members will now be added to the bond and only traffic received after the member was added to the bond will be counted as part of bonding stats. Bonding counters will also be updated when any slaves are dropped to make sure the reported stats are reliable. v2: Changes suggested by Nik to properly allocate/free stats memory. v3: Properly destroy workqueue and fix netlink configuration path. v4: Moved cached stats into bonding and slave structs as there does not seem to be a complexity/performance benefit to using alloc'd memory vs in-struct memory.

2014-09-30net: sched: restrict use of qstats qlenJohn Fastabend
This removes the use of qstats->qlen variable from the classifiers and makes it an explicit argument to gnet_stats_copy_queue(). The qlen represents the qdisc queue length and is packed into the qstats at the last moment before passnig to user space. By handling it explicitely we avoid, in the percpu stats case, having to figure out which per_cpu variable to put it in. It would probably be best to remove it from qstats completely but qstats is a user space ABI and can't be broken. A future patch could make an internal only qstats structure that would avoid having to allocate an additional u32 variable on the Qdisc struct. This would make the qstats struct 128bits instead of 128+32. Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-09-30net: sched: make bstats per cpu and estimator RCU safeJohn Fastabend
In order to run qdisc's without locking statistics and estimators need to be handled correctly. To resolve bstats make the statistics per cpu. And because this is only needed for qdiscs that are running without locks which is not the case for most qdiscs in the near future only create percpu stats when qdiscs set the TCQ_F_CPUSTATS flag. Next because estimators use the bstats to calculate packets per second and bytes per second the estimator code paths are updated to use the per cpu statistics.

2014-09-30ACPI / i915: Update the condition to ignore firmware backlight change requestAaron Lu
Some of the Thinkpads' firmware will issue a backlight change request through i915 operation region unconditionally on AC plug/unplug, the backlight level used is arbitrary and thus should be ignored. This is handled by commit 0b9f7d93ca61 (ACPI / i915: ignore firmware requests for backlight change). Then there is a Dell laptop whose vendor backlight interface also makes use of operation region to change backlight level and with the above commit, that interface no long works. The condition used to ignore the backlight change request from firmware is thus changed to: if the vendor backlight interface is not in use and the ACPI backlight interface is broken, we ignore the requests; oterwise, we keep processing them.
