Changes include: - a lot of s390 changes: optimizations, support for migration, GDB support and more - ARM changes are pretty small: support for the PSCI 0.2 hypercall interface on both the guest and the host (the latter acked by Catalin) - initial POWER8 and little-endian host support - support for running u-boot on embedded POWER targets - pretty large changes to MIPS too, completing the userspace interface and improving the handling of virtualized timer hardware - for x86, a larger set of changes is scheduled for 3.17. Still, we have a few emulator bugfixes and support for running nested fully-virtualized Xen guests (para-virtualized Xen guests have always worked). And some optimizations too. The only missing architecture here is ia64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Old guests try to use the magic page, but map their trampoline code inside of an NX region. Since we can't fix those old kernels, try to detect whether the guest is sane or not. If not, just disable NX functionality in KVM so that old guests at least work at all. For newer guests, add a bit that we can set to keep NX functionality available. Signed-off-by: Alexander Graf <agraf@suse.de>

This includes KVM support for PSCI v0.2 and also includes generic Linux support for PSCI v0.2 (on hosts that advertise that feature via their DT), since the latter depends on headers introduced by the former. Finally there's a small patch from Marc that enables Cortex-A53 support.

We can also inform user space about the 'type' and architecture specific 'flags' of a system-level event using the kvm_run structure.

The following drivers were converted to use the new infrastructure: * ST Microelectronics STiH416 and friends * The Atmel AT91 * The CSR SiRF (Prima2) * The Qualcomm MSM series - massive improvements in the Qualcomm MSM driver from Bjorn Andersson, Andy Gross and Kumar Gala. Among those new support for the IPQ8064 and MSM8x74 SoC variants. - support for the Freescale i.MX6 SoloX SoC variant. - massive improvements in the Allwinner sunxi driver from Boris Brezillon, Maxime Ripard and Chen-Yu Tsai. - Renesas PFC updates from Laurent Pinchart, Kuninori Morimoto, Wolfram Sang and Magnus Damm. - Cleanups and refactorings of the nVidia Tegra driver from Stepgen Warren. - the Exynos driver now supports the Exynos3250 SoC. - Intel BayTrail updates from Jin Yao, Mika Westerberg. - the MVEBU driver now supports the Orion5x SoC variants, which is part of the effort of getting rid of the old Marvell kludges in arch/arm/mach-orion5x - Rockchip driver updates from Heiko Stuebner. - a ton of cleanups and janitorial patches from Axel Lin. - some minor fixes and improvements here and there" * tag 'pinctrl-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (93 commits) pinctrl: sirf: fix a bad conflict resolution pinctrl: msm: Add more MSM8X74 pin definitions pinctrl: qcom: ipq8064: Fix naming convention pinctrl: msm: Add missing sdc1 and sdc3 groups pinctrl: sirf: switch to using allocated state container pinctrl: Enable "power-source" to be extracted from DT files pinctrl: sunxi: create irq/pin mapping during init pinctrl: pinconf-generic: Use kmemdup instead of kmalloc + memcpy pinctrl: berlin: Use devm_ioremap_resource() pinctrl: sirf: fix typo for GPIO bank number pinctrl: sunxi: depend on RESET_CONTROLLER pinctrl: sunxi: fix pin numbers passed to register offset helpers pinctrl: add pinctrl driver for imx6sx pinctrl/at91: Fix lockup when IRQ on PIOC and PIOD occurs pinctrl: msm: switch to using generic GPIO irqchip helpers pinctrl: sunxi: Fix multiple registration issue pinctrl: sunxi: Fix recursive dependency pinctrl: berlin: add the BG2CD pinctrl driver pinctrl: berlin: add the BG2 pinctrl driver pinctrl: berlin: add the BG2Q pinctrl driver ...
