2015-03-11HID: wacom: Provide battery charge state to system over USB if availableJason Gerecke
If a wireless adapter (which contains the charging circuitry) is detected as being attached to the tablet then create a new battery interface and update its status as data is reported. Also destroy the battery if the adapter goes away. Signed-off-by: Jason Gerecke <killertofu@gmail.com> Acked-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2015-03-11HID: wacom: Allow dynamic battery creation/destructionJason Gerecke
Tablets like the Intuos, Intuos Pro, and Bamboo have a connector for an optional wireless module that can be connected on the fly. The presence (or absence) of this module is indicated in a status report recieved from the tablet. This patch adds a workqueue function that will create or destroy a power_supply object at runtime to match the current state of the WACOM_QUIRK_BATTERY flag.

2015-03-11HID: wacom: Move handling of Intuos status packets to seperate functionJason Gerecke
In addition to the touchswitch state for "Intuos", these packets are also sent by the Intuos Pro, Intuos5, and last-generation Bamboo tablets when using a wired connection. They contain, among other things, information about the optional wireless module and battery charge state (to be supported in subsuquent patches).

2015-03-11serial: 8250_dw: Fix deadlock in LCR workaroundPeter Hurley
Trying to write console output from within the serial console driver while the port->lock is held causes recursive deadlock: CPU 0 spin_lock_irqsave(&port->lock) printk() console_unlock() call_console_drivers() serial8250_console_write() spin_lock_irqsave(&port->lock) ** DEADLOCK ** The 8250_dw i/o accessors try to write a console error message if the LCR workaround was unsuccessful. When the port->lock is already held (eg., when called from serial8250_set_termios()), this deadlocks. Make the error message a FIXME until a general solution is devised.

2015-03-11usb: phy: phy-generic: No need to call gpiod_direction_output() twiceFabio Estevam
Commit 9eb0797722895f4309b4 ("usb: phy: generic: fix the gpios to be optional") calls gpiod_direction_output() in the probe function, so there is no need to call it again, as we can simply call gpiod_set_value() directly. Also, in usb_gen_phy_shutdown() we can simply put the GPIO directly in its active level state and this allows us to simplify the nop_reset function to treat only the reset case.

2015-03-11usb: gadget: atmel_usba_udc: Request an auto disabled Vbus signal IRQSylvain Rochet
Vbus IRQ handler needs a started UDC driver to work because it uses udc->driver, which is set by the UDC start handler. The previous way chosen was to return from interrupt if udc->driver is NULL using a spinlock around the check. We now request an auto disabled (IRQ_NOAUTOEN) Vbus signal IRQ instead of an auto enabled IRQ followed by disable_irq(). This way we remove the very small timeslot of enabled IRQ which existed previously between request() and disable(). We don't need anymore to check if udc->driver is NULL in IRQ handler.

This reverts commit ef11982dd7a657512c362242508bb4021e0d67b6. That commit creates a problem for some UDCs (at least musb) where it allocates an endpoints with a 64-byte FIFO, but later tries to use that same FIFO for 1024-byte packets. Before implementing this, composite framework needs to be modified so we only allocate endpoints after we know negotiated speed, however that needs quite a bit of extra work.

2015-03-11arm64: KVM: Do not use pgd_index to index stage-2 pgdMarc Zyngier
The kernel's pgd_index macro is designed to index a normal, page sized array. KVM is a bit diffferent, as we can use concatenated pages to have a bigger address space (for example 40bit IPA with 4kB pages gives us an 8kB PGD. In the above case, the use of pgd_index will always return an index inside the first 4kB, which makes a guest that has memory above 0x8000000000 rather unhappy, as it spins forever in a page fault, whist the host happilly corrupts the lower pgd. The obvious fix is to get our own kvm_pgd_index that does the right thing(tm). Tested on X-Gene with a hacked kvmtool that put memory at a stupidly high address.

This has been tested on an X-Gene platform with a 4kB/48bit-VA host kernel, and kvmtool hacked to place memory in the second page of the hardware PGD (PUD for the host kernel).

2015-03-11Revert "xhci: Clear the host side toggle manually when endpoint is 'soft reset'"Mathias Nyman
This reverts commit 27082e2654dc ("xhci: Clear the host side toggle manually") Turns out this fix to enable soft resetting endpoints wasn't mature enough. It caused regression with some usb DVB-T devices and needs some more tuning to get the endpiont ring pointers set correctly. The original commit was tagged for stable 3.18, and should be reverted from there as well.

2015-03-11drm/radeon: fix wait to actually occur after the signaling callbackMaarten Lankhorst
A normal wait adds to the front of the tail. By doing something similar to fence_default_wait the fence code can run without racing. This is a complete fix for "panic on suspend from KDE with radeon", and a partial fix for "Radeon: System pauses on TAHITI". On tahiti si_irq_set needs to be fixed too, to completely flush the writes before radeon_fence_activity is called in radeon_fence_enable_signaling.

2015-03-11phy: exynos-mipi-video: Use spin_lock to protct state->regmap rmw operationsAxel Lin
The state->regmap is initialized by devm_regmap_init_mmio(). So it's fine to use spin_lock rather than mutex to protct state->regmap rmw operations.

2015-03-10net: Handle unregister properly when netdev namespace change fails.David S. Miller
If rtnl_newlink() fails on it's call to dev_change_net_namespace(), we have to make use of the ->dellink() method, if present, just like we do when rtnl_configure_link() fails.
