IOMMU Updates for Linux v4.2
This time with bigger changes than usual: * A new IOMMU driver for the ARM SMMUv3. This IOMMU is pretty different from SMMUv1 and v2 in that it is configured through in-memory structures and not through the MMIO register region. The ARM SMMUv3 also supports IO demand paging for PCI devices with PRI/PASID capabilities, but this is not implemented in the driver yet. * Lots of cleanups and device-tree support for the Exynos IOMMU driver. This is part of the effort to bring Exynos DRM support upstream. * Introduction of default domains into the IOMMU core code. The rationale behind this is to move functionalily out of the IOMMU drivers to common code to get to a unified behavior between different drivers. The patches here introduce a default domain for iommu-groups (isolation groups). A device will now always be attached to a domain, either the default domain or another domain handled by the device driver. The IOMMU drivers have to be modified to make use of that feature. So long the AMD IOMMU driver is converted, with others to follow. * Patches for the Intel VT-d drvier to fix DMAR faults that happen when a kdump kernel boots. When the kdump kernel boots it re-initializes the IOMMU hardware, which destroys all mappings from the crashed kernel. As this happens before the endpoint devices are re-initialized, any in-flight DMA causes a DMAR fault. These faults cause PCI master aborts, which some devices can't handle properly and go into an undefined state, so that the device driver in the kdump kernel fails to initialize them and the dump fails. This is now fixed by copying over the mapping structures (only context tables and interrupt remapping tables) from the old kernel and keep the old mappings in place until the device driver of the new kernel takes over. This emulates the the behavior without an IOMMU to the best degree possible. * A couple of other small fixes and cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJViSIWAAoJECvwRC2XARrjl+cP/2FXS7SWDq91VFiIZfXfPt8H C5Ef3OGWCnMzn4MKE1ExkyDhC+AH6pF1s4zi3XfT6b8iOA+DUpa51rxJjixszt31 tQwmvB7hWu4mznGxSN7EA0Pm0l/v3tBAY5BvG598af0aNZFFJ6po+31MyQA5X67+ 6xpqLbH/hm4IZhFBOEzZwxuWWsNxlJwwzKqeAjGyqeUhdruRYZiPHWQ17sDjwLM/ QcVvWBb7meOtKv1OCtpzC4sglSk3scbAfEHMEBuDt8cI6OD7/t2VzPXDWWZuXGqK nRAxCT7NrXvyOnv0xwdn0j5p1FUGipVxvhsGWX7sJsh3UHWm8Q+5rRKFFVI9pm50 QcMjiIMazK5VwcAkDnLoDgSz4Zz6TfHXEOqSJ2vjTPt2VDP/J9zdM2iwHx2ujicI mIkrtmsBprvAPx6e9jcqiS5L/Xy1y1xewXuGxa5F2XOjqdoXkPqaupjlyrWzrChA MC8w67FdzjHDPCfIqfIWZpJQj4f1OFQGd3HS5HpkBACxIwCg85gRw4DEMfD/sirO BL2VM0RO/bB5+4R0AY7UA2VszQvNMqedj1bA4vAbrnXqOh8BI/0GgeoWiBMXhyX1 qvT1jl+cxuCm5tgBOMUGYoRyF+//bH+l78jLsTYaWRtuVzFlkAX6idNvYYK0dmNt tLII2IIZBk87P3pF4d6A =Zicw -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "This time with bigger changes than usual: - A new IOMMU driver for the ARM SMMUv3.

Merge branch 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull clkdev updates from Russell King: "This series addresses some breakage in clkdev caused by a previous patch set from the clk tree which introduced per-user clk structures. This basically renamed the existing 'struct clk' to 'struct clk_hw', and introduced a new 'struct clk'. This change will break anyone using clk_add_alias() with the common clk code enabled. Thankfully, the intersection of users of clk_add_alias() and those using the common clk code is practically zero, but this is something which should be fixed to keep the code sane. The problem is that clk_add_alias() does this: r = clk_get(...); l = clkdev_alloc(r, ...); clk_put(...); which causes the alias to store a pointer to 'r', which has been freed. The original patch set tried to work around this problem incorrectly - at clk_get() time, it tried to convert the struct clk to a struct clk_hw, and then creating a new struct clk from that. Clearly, if the original struct clk has been freed, then we have a use-after-free bug. We have other places in the tree which do something similar, so this series also addresses those locations too. This series addresses this problem by converting clkdev to store and use the clk_hw pointer. This allows clk_get() to only have to create it's per-user struct clk from the clk_hw. We can also get to the desired clk_hw at clk_add_alias() or clk lookup creation time, when the struct clk is "alive". We also perform some cleanups of the code: - replacing looped calls to clkdev_add() with clkdev_add_table() - replacing open-coded lookup allocation (which should have been using clkdev_alloc()) and subsequent clkdev_add() with clkdev_create() - replacing open-coded clk_add_alias() with clk_add_alias()" * 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: clk: s2mps11: use clkdev_create() ASoC: migor: use clkdev_create() ARM: omap2: use clkdev_add_alias() ARM: omap2: use clkdev_create() ARM: orion: use clkdev_create() ARM: lpc32xx: convert to use clkdev_add_table() SH: use clkdev_add_table() clkdev: add clkdev_create() helper clkdev: const-ify connection id to clk_add_alias() clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h clkdev: drop __init from clkdev_add_table() clk: update clk API documentation to clarify clk_round_rate() clkdev: use clk_hw internally |

The cpufreq core fixes from Viresh Kumar are quite significant too as far as the number of commits goes and because they should reduce CPU online/offline overhead quite a bit in the majority of cases. From the new featues point of view, the ACPICA update (to upstream revision 20150515) adding support for new ACPI 6 material to ACPICA is the one that matters the most as some new significant features will be based on it going forward. Also included is an update of the ACPI device power management core to follow ACPI 6 (which in turn reflects the Windows' device PM implementation), a PM core extension to support wakeup interrupts in a more generic way and support for the ACPI _CCA device configuration object. The rest is mostly fixes and cleanups all over and some documentation updates, including new DT bindings for Operating Performance Points. There is one fix for a regression introduced in the 4.1 cycle, but it adds quite a number of lines of code, it wasn't really ready before Thursday and you were on vacation, so I refrained from pushing it on the last minute for 4.1.

This is the big bulk of GPIO changes queued for the v4.2
kernel series: - A big set of cleanups to the aged sysfs interface from Johan Hovold. To get these in, v4.1-rc3 was merged into the tree as the first patch in that series had to go into stable.

Pull x86 core updates from Ingo Molnar: "There were so many changes in the x86/asm, x86/apic and x86/mm topics in this cycle that the topical separation of -tip broke down somewhat - so the result is a more traditional architecture pull request, collected into the 'x86/core' topic. The topics were still maintained separately as far as possible, so bisectability and conceptual separation should still be pretty good - but there were a handful of merge points to avoid excessive dependencies (and conflicts) that would have been poorly tested in the end. The next cycle will hopefully be much more quiet (or at least will have fewer dependencies). The main changes in this cycle were: * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas Gleixner) - This is the second and most intrusive part of changes to the x86 interrupt handling - full conversion to hierarchical interrupt domains: [IOAPIC domain] ----- | [MSI domain] --------[Remapping domain] ----- [ Vector domain ] | (optional) | [HPET MSI domain] ----- | | [DMAR domain] ----------------------------- | [Legacy domain] ----------------------------- This now reflects the actual hardware and allowed us to distangle the domain specific code from the underlying parent domain, which can be optional in the case of interrupt remapping. It's a clear separation of functionality and removes quite some duct tape constructs which plugged the remap code between ioapic/msi/hpet and the vector management. - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt injection into guests (Feng Wu) * x86/asm changes: - Tons of cleanups and small speedups, micro-optimizations. This is in preparation to move a good chunk of the low level entry code from assembly to C code (Denys Vlasenko, Andy Lutomirski, Brian Gerst) - Moved all system entry related code to a new home under arch/x86/entry/ (Ingo Molnar) - Removal of the fragile and ugly CFI dwarf debuginfo annotations. Conversion to C will reintroduce many of them - but meanwhile they are only getting in the way, and the upstream kernel does not rely on them (Ingo Molnar) - NOP handling refinements. (Borislav Petkov) * x86/mm changes: - Big PAT and MTRR rework: making the code more robust and preparing to phase out exposing direct MTRR interfaces to drivers - in favor of using PAT driven interfaces (Toshi Kani, Luis R Rodriguez, Borislav Petkov) - New ioremap_wt()/set_memory_wt() interfaces to support Write-Through cached memory mappings. This is especially important for good performance on NVDIMM hardware (Toshi Kani) * x86/ras changes: - Add support for deferred errors on AMD (Aravind Gopalakrishnan) This is an important RAS feature which adds hardware support for poisoned data. That means roughly that the hardware marks data which it has detected as corrupted but wasn't able to correct, as poisoned data and raises an APIC interrupt to signal that in the form of a deferred error. It is the OS's responsibility then to take proper recovery action and thus prolonge system lifetime as far as possible. - Add support for Intel "Local MCE"s: upcoming CPUs will support CPU-local MCE interrupts, as opposed to the traditional system- wide broadcasted MCE interrupts (Ashok Raj) - Misc cleanups (Borislav Petkov) * x86/platform changes: - Intel Atom SoC updates ... and lots of other cleanups, fixlets and other changes - see the shortlog and the Git log for details" * 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (222 commits) x86/hpet: Use proper hpet device number for MSI allocation x86/hpet: Check for irq==0 when allocating hpet MSI interrupts x86/mm/pat, drivers/infiniband/ipath: Use arch_phys_wc_add() and require PAT disabled x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled x86/platform/intel/baytrail: Add comments about why we disabled HPET on Baytrail genirq: Prevent crash in irq_move_irq() genirq: Enhance irq_data_to_desc() to support hierarchy irqdomain iommu, x86: Properly handle posted interrupts for IOMMU hotplug iommu, x86: Provide irq_remapping_cap() interface iommu, x86: Setup Posted-Interrupts capability for Intel iommu iommu, x86: Add cap_pi_support() to detect VT-d PI capability iommu, x86: Avoid migrating VT-d posted interrupts iommu, x86: Save the mode (posted or remapped) of an IRTE iommu, x86: Implement irq_set_vcpu_affinity for intel_ir_chip iommu: dmar: Provide helper to copy shared irte fields iommu: dmar: Extend struct irte for VT-d Posted-Interrupts iommu: Add new member capability to struct irq_remap_ops x86/asm/entry/64: Disentangle error_entry/exit gsbase/ebx/usermode code x86/asm/entry/32: Shorten __audit_syscall_entry() args preparation x86/asm/entry/32: Explain reloading of registers after __audit_syscall_entry() ... |

HSI: cmt_speech: fix timestamp interface
The user interface for timestamps in the new cmt_speech driver is broken in multiple ways: - The layout is incompatible between 32-bit and 64-bit user space, because of the size differences in 'struct timespec'. This means that the driver can not work when used with 32-bit user space on a 64-bit kernel. - As there are plans to change 32-bit user space to use a 64-bit time_t type in the future, it will also be incompatible with new 32-bit user space. - It is using ktime_get_ts under it's deprecated alias (do_posix_clock_monotonic_gettime). To keep support for the user space tools written for this driver (which have lived many years out-of-tree), the interface has been hardened to unsigned 32-bit values.
