The init functions do not return any error.

2016-06-28bonding: fix 802.3ad aggregator reselectionJay Vosburgh
Since commit 7bb11dc9f59d ("bonding: unify all places where actor-oper key needs to be updated."), the logic in bonding to handle selection between multiple aggregators has not functioned. This affects only configurations wherein the bonding slaves connect to two discrete aggregators (e.g., two independent switches, each with LACP enabled), thus creating two separate aggregation groups within a single bond. The cause is a change in 7bb11dc9f59d to no longer set AD_PORT_BEGIN on a port after a link state change, which would cause the port to be reselected for attachment to an aggregator as if were newly added to the bond. We cannot restore the prior behavior, as it contradicts IEEE 802.1AX 5.4.12, which requires ports that "become inoperable" (lose carrier, setting port_enabled=false as per 802.1AX 5.4.7) to remain selected (i.e., assigned to the aggregator). As the port now remains selected, the aggregator selection logic is not invoked. A side effect of this change is that aggregators in bonding will now contain ports that are link down. The aggregator selection logic does not currently handle this situation correctly, causing incorrect aggregator selection. This patch makes two changes to repair the aggregator selection logic in bonding to function as documented and within the confines of the standard: First, the aggregator selection and related logic now utilizes the number of active ports per aggregator, not the number of selected ports (as some selected ports may be down). The ad_select "bandwidth" and "count" options only consider ports that are link up. Second, on any carrier state change of any slave, the aggregator selection logic is explicitly called to insure the correct aggregator is active.

2016-06-28clocksource/drivers/clksrc-probe: Introduce init functions with return codeDaniel Lezcano
Currently, the clksrc-probe is not able to handle any error from the init functions. There are different issues with the current code: - the code is duplicated in the init functions by writing error - every driver tends to panic in its own init function - counting the number of clocksources is not reliable This patch adds another table to store the functions returning an error. The table is temporary while we convert all the drivers to return an error and will disappear. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>

Add clocksource and clockevent driver from dual RPS timer. The HW provides a dual one-shot or periodic 24bit timers, the drivers set the first one as tick event source and the second as a continuous scheduler clock source. The timer can use 1, 16 or 256 as pre-dividers, thus the clocksource uses 16 by default.
