2012-04-13sparc64: Eliminate obsolete __handle_softirq() functionPaul E. McKenney
The invocation of softirq is now handled by irq_exit(), so there is no need for sparc64 to invoke it on the trap-return path. In fact, doing so is a bug because if the trap occurred in the idle loop, this invocation can result in lockdep-RCU failures. The problem is that RCU ignores idle CPUs, and the sparc64 trap-return path to the softirq handlers fails to tell RCU that the CPU must be considered non-idle while those handlers are executing. This means that RCU is ignoring any RCU read-side critical sections in those handlers, which in turn means that RCU-protected data can be yanked out from under those read-side critical sections. The shiny new lockdep-RCU ability to detect RCU read-side critical sections that RCU is ignoring located this problem. The fix is straightforward: Make sparc64 stop manually invoking the softirq handlers. Reported-by: Meelis Roos <mroos@linux.ee> Suggested-by: David Miller <davem@davemloft.net> Signed-off-by: Paul E.

The DS driver registers as a subsys_initcall() but this can be too early, in particular this risks registering before we've had a chance to allocate and setup module_kset in kernel/params.c which is performed also as a subsyts_initcall().

2012-04-13brcm80211: smac: only provide valid regulatory hintArend van Spriel
The driver provides a regulatory hint to cfg80211 as obtained from the SPROM. Mostly, this will be a two-letter ISO country code. However, it may obtain special country code similar to the world regulatory domain as used in cfg80211. This patch avoids setting these special codes as the hint is lost to cfg80211.

2012-04-13brcm80211: smac: do not use US as fallback regulatory hintArend van Spriel
The brcmsmac driver provides the country code from sprom as a regulatory hint to cfg80211. When brcmsmac does not find a country code entry in the sprom it passes 'US' as regulatory hint. Better approach is to rely on the world regulatory domain in cfg80211/crda.

The MAX_TXPWR table for BTCOEX is not needed for AR9462. Programming these values to the HW results in undesirable behavior - for example, large number of delimiter/data underruns are seen in AES-CCMP mode. Also, registers like AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX power table is programmed to the HW, and frames being transmitted end up being looped back to the RX engine, an example being beacon frames in IBSS mode.
