2017-02-16drm/i915: Let execlist_update_context() cover !FULL_PPGTT mode.Zhi Wang
execlist_update_context() will try to update PDPs in a context before a ELSP submission only for full PPGTT mode, while PDPs was populated during context initialization. Now the latter code path is removed. Let execlist_update_context() also cover !FULL_PPGTT mode.

2017-02-16drm/i915/lspcon: Fix resume time initialization due to unasserted HPDImre Deak
During system resume time initialization the HPD level on LSPCON ports can stay low for an extended amount of time, leading to failed AUX transfers and LSPCON initialization.

2017-02-16drm/i915/gen9+: Enable hotplug detection earlyImre Deak
For LSPCON resume time initialization we need to sample the corresponding pin's HPD level, but this is only available when HPD detection is enabled. Currently we enable detection only when enabling HPD interrupts which is too late, so bring the enabling of detection earlier. This is needed by the next patch.

In commit 957870f93412 ("drm/i915: Split out i915_gem_object_set_tiling()"), I swapped an alignment check for IS_ALIGNED and in the process removed the less-than check.

2017-02-16ALSA: x86: Avoid register accesses during disconnectionTakashi Iwai
It seems that accessing registers during disconnection often leads to the GPU pipe error. The original driver had a similar check in the past, but it was lost through refactoring. Now put a connection check in the register access functions. One exception is the irq handler: it still needs to access the raw register even while disconnected, because it has to read and write to ACK the irq mask. Although the irq shouldn't be raised while disconnected (the stream should have been disabled), let's make it safer for now. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2017-02-16KVM: PPC: Book3S HV: Prevent double-free on HPT resize commit pathDavid Gibson
resize_hpt_release(), called once the HPT resize of a KVM guest is completed (successfully or unsuccessfully) frees the state structure for the resize. It is currently not safe to call with a NULL pointer. However, one of the error paths in kvm_vm_ioctl_resize_hpt_commit() can invoke it with a NULL pointer. This will occur if userspace improperly invokes KVM_PPC_RESIZE_HPT_COMMIT without previously calling KVM_PPC_RESIZE_HPT_PREPARE, or if it calls COMMIT twice without an intervening PREPARE. To fix this potential crash bug - and maybe others like it, make it safe (and a no-op) to call resize_hpt_release() with a NULL resize pointer. Found by Dan Carpenter with a static checker.

2017-02-16async_tx: deprecate broken support for channel switchingDan Williams
Back in 2011, Russell pointed out that the "async_tx channel switch" capability was violating expectations of the dma mapping api [1]. At the time the existing uses were reviewed as still usable, but that longer term we needed a rework of the raid offload implementation. While some of the framework for a fixed implementation was introduced in 2012 [2], the wider rewrite never materialized. There continues to be interest in raid offload with new dma/raid engine drivers being submitted. Those drivers must not build on top of the broken channel switching capability. Prevent async_tx from using an offload engine if the channel switching capability is enabled. This still allows the engine to be used for other purposes, but the broken way async_tx uses these engines for raid will be disabled. For configurations where this causes a performance regression the only solution is to start the work of eliminating the async_tx api and moving channel management into the raid code directly where it can manage marshalling an operation stream between multiple dma channels.

2017-02-16powerpc/64: Disable use of radix under a hypervisorPaul Mackerras
Currently, if the kernel is running on a POWER9 processor under a hypervisor, it may try to use the radix MMU even though it doesn't have the necessary code to do so (it doesn't negotiate use of radix, and it doesn't do the H_REGISTER_PROC_TBL hcall). If the hypervisor supports both radix and HPT, then it will set up the guest to use HPT (since the guest doesn't request radix in the CAS call), but if the radix feature bit is set in the ibm,pa-features property (which is valid, since ibm,pa-features is defined to represent the capabilities of the processor) the guest will try to use radix, resulting in a crash when it turns the MMU on. This makes the minimal fix for the current code, which is to disable radix unless we are running in hypervisor mode.

2017-02-15tty: pl011: Work around QDF2400 E44 stuck BUSY bitChristopher Covington
The Qualcomm Datacenter Technologies QDF2400 family of SoCs contains a custom (non-PrimeCell) implementation of the SBSA UART. Occasionally the BUSY bit in the Flag Register gets stuck as 1, erratum 44 for both 2432v1 and 2400v1 SoCs.Checking that the Transmit FIFO Empty (TXFE) bit is 0, instead of checking that the BUSY bit is 1, works around the issue. To facilitate this substitution of flags and values, introduce vendor-specific inversion of Feature Register bits when UART AMBA Port (UAP) data is available. For the earlycon case, prior to UAP availability, implement alternative putc and early_write functions. Similar to what how ARMv8 ACPI PCI quirks are detected during MCFG parsing, check the OEM fields of the Serial Port Console Redirection (SPCR) ACPI table to determine if the current platform is known to be affected by the erratum.

2017-02-15atm: idt77252, use setup_timer and mod_timerJan Koniarik
Stop accessing timer struct members directly and use setup_timer and mod_timer helpers intended for that use. It makes the code cleaner and will allow for easier change of the timer struct internals.

2017-02-15mlxsw: acl: Use PBS type for forward actionJiri Pirko
Current behaviour of "mirred redirect" action (forward) offload is a bit odd. For matched packets the action forwards them to the desired destination, but it also lets the packet duplicates to go the original way down (bridge, router, etc). That is more like "mirred mirror". Fix this by using PBS type which behaves exactly like "mirred redirect". Note that PBS does not support loopback mode.
