2010-11-23drm/i915/sdvo: Always fallback to querying the shared DDC lineChris Wilson
On a few devices, like the Mac Mini, the CRT DDC pins are shared between the analog connector and the digital connector. In this scenario, rely on the EDID to determine if a digital panel is connected to the digital connector.

2010-11-23ARM: 6490/1: MM: bugfix: initialize spinlock for init_mm.contextMyungJoo Ham
init_mm used at kernel/sched.c:idle_task_exit() has spin_lock (init_mm.context.id_lock) that is not initialized when spin_lock/unlock is called at an ARM machine. Note that mm_struct.context.id_lock is usually initialized except for the instance of init_mm at linux/arch/arm/mm/context.c Not initializing this spinlock incurs "BUG: pinlock bad magic" warning when spinlock debug is enabled. We have observed such instances when testing PM in S5PC210 machines.

2010-11-23drm/i915: Handle pagefaults in execbuffer user relocationsChris Wilson
Currently if we hit a pagefault when applying a user relocation for the execbuffer, we bail and return EFAULT to the application. Instead, we need to unwind, drop the dev->struct_mutex, copy all the relocation entries to a vmalloc array (to avoid any potential circular deadlocks when resolving the pagefault), retake the mutex and then apply the relocations. Afterwards, we need to again drop the lock and copy the vmalloc array back to userspace. v2: Incorporate feedback from Daniel Vetter.

2010-11-23perf symbols: Remove incorrect open-coded container_of()Rabin Vincent
At least on ARM, padding is inserted between rb_node and sym in struct symbol_name_rb_node, causing "((void *)sym) - sizeof(struct rb_node)" to point inside rb_node rather than to the symbol_name_rb_node.

It seems that using ath9k_hw_stoppcurecv to stop rx dma is not enough. When it's time to stop DMA, the PCU is still busy, so the rx enable bit never clears.

2010-11-22mmc: sdhci: 8-bit bus width changesPhilip Rakity
We now: * check for a v3 controller before setting 8-bit bus width * offer a callback for platform code to switch to 8-bit mode, which allows non-v3 controllers to support it * rely on mmc->caps |= MMC_CAP_8_BIT_DATA; in platform code to specify that the board designers have indeed brought out all the pins for 8-bit to the slot. We were previously relying only on whether the *controller* supported 8-bit, which doesn't tell us anything about the pin configuration in the board design. This fixes the MMC card regression reported by Maxim Levitsky here: http://thread.gmane.org/gmane.linux.kernel.mmc/4336 by no longer assuming that 8-bit works by default.

2010-11-22xen/events: Use PIRQ instead of GSI value when unmapping MSI/MSI-X irqs.Konrad Rzeszutek Wilk
When we allocate a vector for MSI/MSI-X we save away the PIRQ, and the vector value. When we unmap (de-allocate) the MSI/MSI-X vector(s) we need to provide the PIRQ and the vector value. What we did instead was to provide the GSI (which was zero) and the vector value, and we got these unhappy error messages: (XEN) irq.c:1575: dom0: pirq 0 not mapped [ 7.733415] unmap irq failed -22 This patches fixes this and we use the PIRQ value instead of the GSI value.

If the rpcauth_refreshcred() call returns an error other than EACCES, ENOMEM or ETIMEDOUT, we currently end up looping forever between call_refresh and call_refreshresult. The correct thing to do here is to exit on all errors except EAGAIN and ETIMEDOUT, for which case we retry 3 times, then return EACCES. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-11-22of/phylib: Use device tree properties to initialize Marvell PHYs.David Daney
Some aspects of PHY initialization are board dependent, things like indicator LED connections and some clocking modes cannot be determined by probing. The dev_flags element of struct phy_device can be used to control these things if an appropriate value can be passed from the Ethernet driver. We run into problems however if the PHY connections are specified by the device tree. There is no way for the Ethernet driver to know what flags it should pass. If we are using the device tree, the struct phy_device will be populated with the device tree node corresponding to the PHY, and we can extract extra configuration information from there. The next question is what should the format of that information be? It is highly device specific, and the device tree representation should not be tied to any arbitrary kernel defined constants. A straight forward representation is just to specify the exact bits that should be set using the "marvell,reg-init" property: phy5: ethernet-phy@5 { reg = <5>; compatible = "marvell,88e1149r"; marvell,reg-init = /* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */ <3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */ /* mix %:0, led[0123]:drive low off hiZ */ <3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */ /* default blink periods. */ <3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */ /* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */ <3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */ }; phy6: ethernet-phy@6 { reg = <6>; compatible = "marvell,88e1118"; marvell,reg-init = /* Fix rx and tx clock transition timing */ <2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */ /* Adjust LED drive. */ <3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */ /* irq, blink-activity, blink-link */ <3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */ }; The Marvell PHYs have a page select register at register 22 (0x16), we can specify any register by its page and register number. These are the first and second word. The third word contains a mask to be ANDed with the existing register value, and the fourth word is ORed with the result to yield the new register value. The new marvell_of_reg_init function leaves the page select register unchanged, so a call to it can be dropped into the .config_init functions without unduly affecting the state of the PHY. If CONFIG_OF_MDIO is not set, there is no of_node, or no "marvell,reg-init" property, the PHY initialization is unchanged.

2010-11-22phylib: Add support for Marvell 88E1149R devices.David Daney
The 88E1149R is 10/100/1000 quad-gigabit Ethernet PHY. The .config_aneg function can be shared with 88E1118, but it needs its own .config_init.
