2013-05-22cpufreq: arm_big_little_dt: Instantiate as platform_driverViresh Kumar1-5/+15
As multiplatform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when both arm_big_little_dt and cpufreq-cpu0 drivers are compiled in, arm_big_little_dt driver may try to register even if we had platform device for cpufreq-cpu0 registered. To eliminate this undesired the effect, the patch changes arm_big_little_dt driver to have it instantiated as a platform_driver. Then it will only run on platforms that create the platform_device "arm-bL-cpufreq-dt".

2013-05-22cpufreq: arm_big_little_dt: Register driver only if DT has valid dataViresh Kumar1-31/+42
If arm_big_little_dt driver is enabled, then it will always try to register with big LITTLE cpufreq core driver. In case DT doesn't have relevant data for cpu nodes, i.e. operating points aren't present, then we should exit early and shouldn't register with big LITTLE cpufreq core driver. Otherwise we will fail continuously from the driver->init() routine. This patch fixes this issue.

2013-05-22ARM: shmobile: marzen: Use error values in usb_power_*Simon Horman1-3/+3
This patch updates the marzen board code as if USB PHY isn't enabled they phy will have a value set by ERR_PTR() rather than be NULL. Without this patch a NULL pointer dereference and kernel panic occurs on initialisation of USB on marzen. This resolves a regression introduced in 3.10-rc1 by b7fa5c2aec5be083eb2719b405089703608e9bc6 ("usb: phy: return -ENXIO when PHY layer isn't enabled").

2013-05-22MIPS: Idle: Break r4k_wait into two functions and fix it.Ralf Baechle3-4/+11
local_irq_enable() may expand into very different code, so it rather should stay in C. Also this keeps the assembler code size constant which keeps the rollback code simple. So it's best to split r4k_wait into two parts, one C and one assembler. Finally add the local_irq_enable() to r4k_wait to ensure the WAIT instruction in __r4k_wait() will work properly.

2013-05-22ACPI / PM: Allow device power states to be used for CONFIG_PM unsetRafael J. Wysocki3-98/+70
Currently, drivers/acpi/device_pm.c depends on CONFIG_PM and all of the functions defined in there are replaced with static inline stubs if that option is unset. However, CONFIG_PM means, roughly, "runtime PM or suspend/hibernation support" and some of those functions are useful regardless of that. For example, they are used by the ACPI fan driver for controlling fans and acpi_device_set_power() is called during device removal. Moreover, device initialization may depend on setting device power states properly. For these reasons, make the routines manipulating ACPI device power states defined in drivers/acpi/device_pm.c available for CONFIG_PM unset too.

2013-05-21leds: leds-gpio: reserve gpio before using itTimo Teräs1-4/+5
This reverts commit a99d76f (leds: leds-gpio: use gpio_request_one) and commit 2d7c22f (leds: leds-gpio: set devm_gpio_request_one() flags param correctly) which was a fix of the first one. The conversion to devm_gpio_request in commit e3b1d44c (leds: leds-gpio: use devm_gpio_request_one) is not reverted. The problem is that gpio_cansleep() and gpio_get_value_cansleep() calls can crash if the gpio is not first reserved. Incidentally this same bug existed earlier and was fixed similarly in commit d95cbe61 (leds: Fix potential leds-gpio oops). But the OOPS is real. It happens when GPIOs are provided by module which is not yet loaded.

There is a race between klist_remove and klist_release. klist_remove uses a local var waiter saved on stack. When klist_release calls wake_up_process(waiter->process) to wake up the waiter, waiter might run immediately and reuse the stack. Then, klist_release calls list_del(&waiter->list) to change previous wait data and cause prior waiter thread corrupt. The patch fixes it against kernel 3.9.

port tty_port_init() zeroes out the tty port, which means that we have to set the ops pointer /after/, not before this call. Otherwise, tty_port_open will crash when it tries to deref ops, which is now a NULL pointer. Signed-off-by: Darrick J. Wong <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

Before f7b861b7a6d9 ("arm: Use generic idle loop") ARM would kill the CPU within the rcu idle section. Now that the rcu_idle_enter()/exit() pair have been pushed lower down in the idle loop this is no longer true and so using RCU_NONIDLE here is no longer necessary and also harmful because RCU is not actually idle at this point.

The AK8975 Kconfig option was renamed during the 3.10 merge window. Adjust tegra_defconfig to enable the new name, so it's not missing useful features. Tegra DRM support used to be enabled in the default Tegra configuration, but it now depends on CONFIG_TEGRA_HOST1X which is disabled by default. Enable CONFIG_TEGRA_HOST1X so that DRM support is compiled in again.

The assignment of IRQ for the SMC91x ethernet adapter had two problems making it non-working: - It was not put into the ethernet device node. Let's do this by using the board-specific overlay, so we can make other overlays on other Nomadik boards. - The IRQ number was actually completely wrong, this was the number for NHK8815, not S8815.
