2017-09-01MAINTAINERS: use the iommu list for the dma-mapping subsystemChristoph Hellwig
Maintaining a subsystem with linux-kernel as the main list is painful as it has way to much traffic. On the other hand the dma-mapping subsystem is small enough that a list on its own would be silly. So use the list for the closes subsystem instead instead.

2017-08-30ARC: clk: introduce HSDK pll driverEugeniy Paltsev
HSDK board manages its clocks using various PLLs. These PLL have same dividers and corresponding control registers mapped to different addresses. So we add one common driver for such PLLs. Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and ODIV. Output clock value is managed using these dividers. We add pre-defined tables with supported rate values and appropriate configurations of IDIV, FBDIV and ODIV for each value. As of today we add support for PLLs that generate clock for the HSDK arc cpus, system, ddr, AXI tunnel and hdmi. By this patch we add support for several plls (arc cpus pll and others), so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll and regular probing for others plls.

2017-08-30MIPS: generic: Allow filtering enabled boards by requirementsPaul Burton
Up until now when configuring a generic kernel all board config fragments have been merged by default unless boards are explicitly selected by the user specifying BOARDS=. In many cases this is sub-optimal, since some boards don't make sense to include in some kernels. For example the MIPS SEAD-3 development board has only ever been used with 32 bit CPUs, so including support for the SEAD-3 in a 64 bit kernel is wasteful. This patch introduces support for specifying requirements in board config fragments, using comments formatted like so: # require CONFIG_BLA=y For example the SEAD-3 board could specify that it should only be merged for 32 bit kernels using a requirement line like the following: # require CONFIG_32BIT=y A new generic-board-config.sh script is introduced to handle selecting the board config fragments to merge & calling merge_config.sh to merge them. In order to allow requirements to check Kconfig symbols that are implicitly selected, rather than explicitly specified by generic_defconfig or one of the ISA config fragments, an intermediate .config file is saved & used as a reference when checking requirements.

2017-08-29MIPS: math-emu: RINT.<D|S>: Fix several problems by reimplementationAleksandar Markovic
Reimplement RINT.<D|S> kernel emulation so that all RINT.<D|S> specifications are met. For the sake of simplicity, let's analyze RINT.S only. Prior to this patch, RINT.S emulation was essentially implemented as (in pseudocode) <output> = ieee754sp_flong(ieee754sp_tlong(<input>)), where ieee754sp_tlong() and ieee754sp_flong() are functions providing conversion from double to integer, and from integer to double, respectively. On surface, this implementation looks correct, but actually fails in many cases. Following problems were detected: 1. NaN and infinity cases will not be handled properly. The function ieee754sp_flong() never returns NaN nor infinity. 2. For RINT.S, for all inputs larger than LONG_MAX, and smaller than FLT_MAX, the result will be wrong, and the overflow exception will be erroneously set. A similar problem for negative inputs exists as well. 3. For some rounding modes, for some negative inputs close to zero, the return value will be zero, and should be -zero. This is because ieee754sp_flong() never returns -zero. This patch removes the problems above by implementing dedicated functions for RINT.<D|S> emulation. The core of the new function functionality is adapted version of the core of the function ieee754sp_tlong(). However, there are many details that are implemented to match RINT.<D|S> specification. It should be said that the functionality of ieee754sp_tlong() actually closely corresponds to CVT.L.S instruction, and it is used while emulating CVT.L.S. However, RINT.S and CVT.L.S instructions differ in many aspects. This patch fulfills missing support for RINT.<D|S>.

With hv_sock, applications between the host (Windows 10, Windows Server 2016 or newer) and the guest can talk with each other using the traditional socket APIs. More info about Hyper-V Sockets is available here: "Make your own integration services": https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/make-integration-service The patch implements the necessary support in Linux guest by introducing a new vsock transport for AF_VSOCK.

2017-08-20phy: phy-mt65xx-usb3: add mediatek directory and rename fileChunfeng Yun
The driver is actually for T-PHY which supports USB3.0, PCIe and SATA, and supports more SoCs now, but not just only for series of mt65xx SoCs, so the name of file, data struct, functions etc with 'mt65xx' may cause misunderstanding when new SoCs are supported. Here rename them to reflect the real functions and also enhance readability. And also update MAINTAINERS file to reflect the correct driver Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2017-08-18MAINTAINERS: Remove Jason Cooper's irqchip git treeFlorian Fainelli
Jason's irqchip tree does not seem to have been updated for many months now, remove it from the list of trees to avoid any possible confusion. Jason says: "Unfortunately, when I have time for irqchip, I don't always have the time to properly follow up with pull-requests. So, for the time being, I'll stick to reviewing as I can."

2017-08-18MAINTAINERS: drm/i915 has a new maintainer teamDaniel Vetter
For a bunch of reasons[1] I've decided to step down as maintainer and let some other folks enjoy the reputation and hang out in the spotlight. Jani is going to stick around with his expertise in kms and having done the fixes flow for a long time now. Joonas will join and bring in his knowledge on all things GEM. Rodrigo has been less visible because he's been doing tons of work taking care of the internal branch, and it'd be good to have more continuity between these two worlds also on the maintainer side. 1: They all boil down to: This is going to happen sooner or later anyway, we have a great team, with the process improvements over the last few years things work rather well, now is as good as any time to do this. With that change I'll have more time for other aspects of the stack development than maintainership.
