2012-09-24mwifiex: fix issue in resumed scan operationAmitkumar Karwar
When delayed scan operation is resumed, we just add next scan command in queue but don't wakeup main thread to process the command. Hence the command is downloaded to firmware only after waking up the main thread by any other means. This bug which was introduced after "mwifiex: improve scan delay logic.." patch is fixed here.

Upon handling an e-scan result event from the firmware in brcmf_cfg80211_escan_handler() the status may indicate e-scan is completed or aborted. If so brcmf_notify_escan_complete() is called. However, that function and brcmf_cfg80211_escan_handler() both log the same debug message and both enable MPC flag in the firmware.

2012-09-24brcmfmac: clear status for in-band interrupt in brcmf_sdbrcm_isrFranky Lin
SDIO in-band interrupt is level sensitive according to SDIO standard. When the register interrupt handler gets called by SDIO stack it is running in non interrupt context and expected to clear the interrupt from the dongle. Therefore in-band and out-of-band interrupt need to be handled differently.

A recent patch in the linux-next tree caused a build failure on C6X because C6X didn't define a read_barrier_depends() macro. C6X does not support SMP and the architecture doesn't provide any special memory ordering instructions, so it makes sense to just use the generic barrier.h rather than patching the existing c6x specific header.

2012-09-24trace: Move trace event enable from fs_initcall to core_initcallEzequiel Garcia
This patch splits trace event initialization in two stages: * ftrace enable * sysfs event entry creation This allows to capture trace events from an earlier point by using 'trace_event' kernel parameter and is important to trace boot-up allocations. Note that, in order to enable events at core_initcall, it's necessary to move init_ftrace_syscalls() from core_initcall to early_initcall.

2012-09-24tracing: Add an option for disabling markersMandeep Singh Baines
In our application, we have trace markers spread through user-space. We have markers in GL, X, etc. These are super handy for Chrome's about:tracing feature (Chrome + system + kernel trace view), but can be very distracting when you're trying to debug a kernel issue. I normally, use "grep -v tracing_mark_write" but it would be nice if I could just temporarily disable markers all together.

2012-09-24ARM: OMAP4: twl-common: Support for additional devices on i2c1 busPeter Ujfalusi
On OMAP4 the i2c1 bus is dedicated for the PMIC and audio related devices. Manufacturers can opt to use different codec than twl6040 and also can add audio related IC to the bus (external amplifier for example on SDP4430). Make it possible to add different set of additional devices to i2c1 bus on OMAP4 boards.

2012-09-24irqchip: fill in empty KconfigStephen Warren
Commit 89214f0 "ARM: bcm2835: add interrupt controller driver" added an empty drivers/irqchip/Kconfig. Empty files apparently don't work well with git (sometimes, with some versions?) so add some dummy content to resolve this issue.
