mm: new mm hook framework
CRIU is recreating the process memory layout by remapping the checkpointee memory area on top of the current process (criu). This includes remapping the vDSO to the place it has at checkpoint time. However some architectures like powerpc are keeping a reference to the vDSO base address to build the signal return stack frame by calling the vDSO sigreturn service. So once the vDSO has been moved, this reference is no more valid and the signal frame built later are not usable. This patch serie is introducing a new mm hook framework, and a new arch_remap hook which is called when mremap is done and the mm lock still hold. The next patch is adding the vDSO remap and unmap tracking to the powerpc architecture. This patch (of 3): This patch introduces a new set of header file to manage mm hooks: - per architecture empty header file (arch/x/include/asm/mm-arch-hooks.h) - a generic header (include/linux/mm-arch-hooks.h) The architecture which need to overwrite a hook as to redefine it in its header file, while architecture which doesn't need have nothing to do. The default hooks are defined in the generic header and are used in the case the architecture is not defining it. In a next step, mm hooks defined in include/asm-generic/mm_hooks.h should be moved here.

arm64 updates for 4.2, mostly refactoring/clean-up:
- CPU ops and PSCI (Power State Coordination Interface) refactoring
following the merging of the arm64 ACPI support, together with
handling of Trusted (secure) OS instances
- Using fixmap for permanent FDT mapping, removing the initial dtb
placement requirements (within 512MB from the start of the kernel
image). This required moving the FDT self reservation out of the
memreserve processing
- Idmap (1:1 mapping used for MMU on/off) handling clean-up
- Removing flush_cache_all() - not safe on ARM unless the MMU is off.
Last stages of CPU power down/up are handled by firmware already
- "Alternatives" (run-time code patching) refactoring and support for
immediate branch patching, GICv3 CPU interface access
- User faults handling clean-up
And some fixes:
- Fix for VDSO building with broken ELF toolchains
- Fixing another case of init_mm.pgd usage for user mappings (during
ASID roll-over broadcasting)
- Fix for FPSIMD reloading after CPU hotplug
- Fix for missing syscall trace exit
- Workaround for .inst asm bug
- Compat fix for switching the user tls tpidr_el0 register

Merge branch 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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"

This provides the functionality to fix a problem reported by Kevin Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2 kernel because the platform's firmware always enters the kernel in ARM mode from deep idle states.

arch/*/io.h: Add ioremap_wt() to all architectures

Some of them include <asm-generic/io.h>, but ioremap_wt() is defined for consistency since they define all ioremap_xxx locally. In all architectures without Write-Through support, ioremap_wt() is defined indentical to ioremap_nocache(). frv and m68k already have ioremap_writethrough(). On those we add ioremap_wt() indetical to ioremap_writethrough() and defines ARCH_HAS_IOREMAP_WT in both architectures. The ioremap_wt() interface is exported to drivers.

EDAC: Cleanup atomic_scrub mess
So first of all, this atomic_scrub() function's naming is bad. It looks like an atomic_t helper. Change it to edac_atomic_scrub(). The bigger problem is that this function is arch-specific and every new arch which doesn't necessarily need that functionality still needs to define it, otherwise EDAC doesn't compile. So instead of doing that and including arch-specific headers, have each arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c for ifdeffery. Much cleaner. And we already are doing this with another symbol - EDAC_SUPPORT. This is also much cleaner than having CONFIG_EDAC enumerate all the arches which need/have EDAC support and drivers. This way I can kill the useless edac.h header in tile too.

ARM: SoC driver updates for v4.1
Driver updates for v4.1. Some of these are for drivers/soc, where we find more
and more SoC-specific drivers these days. Some are for other driver subsystems
where we have received acks from the appropriate maintainers.
The larger parts of this branch are:
- MediaTek support for their PMIC wrapper interface, a high-level interface
for talking to the system PMIC over a dedicated I2C interface.
- Qualcomm SCM driver has been moved to drivers/firmware. It's used for CPU
up/down and needs to be in a shared location for arm/arm64 common code.
- Cleanup of ARM-CCI PMU code.
- Anoter set of cleanusp to the OMAP GPMC code.

ARM: SoC platform updates for v4.1
Our SoC branch usually contains expanded support for new SoCs and other core
platform code. In this case, that includes:
- Support for the new Annapurna Labs "Alpine" platform
- A rework greatly simplifying adding new platform support to the MCPM
subsystem (Multi-cluster power management)
- Cpuidle and PM improvements for Exynos3250
- Misc updates for Renesas, OMAP, Meson, i.MX. Some of these could have
gone in other branches but ended up here for various reasons.

ARM: SoC cleanups for v4.1
We've got a fairly large cleanup branch this time. The bulk of this is removal
of non-DT platforms of several flavors:
- Atmel at91 platforms go full-DT, with removal of remaining board-file based
support
- OMAP removes legacy board files for three more platforms
- Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom
- Freescale i.MX25 also removes non-DT platform support
Most of the rest of the changes here are fallout from the above, i.e. for
example removal of drivers that now lack platforms, etc.

KVM: arm/arm64: check IRQ number on userland injection
When userland injects a SPI via the KVM_IRQ_LINE ioctl we currently only check it against a fixed limit, which historically is set to 127. With the new dynamic IRQ allocation the effective limit may actually be smaller (64). So when now a malicious or buggy userland injects a SPI in that range, we spill over on our VGIC bitmaps and bytemaps memory. I could trigger a host kernel NULL pointer dereference with current mainline by injecting some bogus IRQ number from a hacked kvmtool: ----------------- .... DEBUG: kvm_vgic_inject_irq(kvm, cpu=0, irq=114, level=1) DEBUG: vgic_update_irq_pending(kvm, cpu=0, irq=114, level=1) DEBUG: IRQ #114 still in the game, writing to bytemap now... Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = ffffffc07652e000 [00000000] *pgd=00000000f658b003, *pud=00000000f658b003, *pmd=0000000000000000 Internal error: Oops: 96000006 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 1053 Comm: lkvm-msi-irqinj Not tainted 4.0.0-rc7+ #3027 Hardware name: FVP Base (DT) task: ffffffc0774e9680 ti: ffffffc0765a8000 task.ti: ffffffc0765a8000 PC is at kvm_vgic_inject_irq+0x234/0x310 LR is at kvm_vgic_inject_irq+0x30c/0x310 pc : [<ffffffc0000ae0a8>] lr : [<ffffffc0000ae180>] pstate: 80000145 ..... So this patch fixes this by checking the SPI number against the actual limit. Also we remove the former legacy hard limit of 127 in the ioctl code.

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
"Included in this update are both some long term fixes and some new
features.
Fixes:
- An integer overflow in the calculation of ELF_ET_DYN_BASE.
- Avoiding OOMs for high-order IOMMU allocations
- SMP requires the data cache to be enabled for synchronisation
primitives to work, so prevent the CPU_DCACHE_DISABLE option being
visible on SMP builds.
- A bug going back 10+ years in the noMMU ARM94* CPU support code,
where it corrupts registers. Found by folk getting Linux running
on their cameras.
- Versatile Express needs an errata workaround enabled for CPU
hot-unplug to work.
Features:
- Clean up module linker by handling out of range relocations
separately from relocation cases we don't handle.
- Fix a long term bug in the pci_mmap_page_range() code, which we
hope won't impact userspace (we hope there's no users of the
existing broken interface.)
- Don't map DMA coherent allocations when we don't have a MMU.
- Drop experimental status for SMP_ON_UP.
- Warn when DT doesn't specify ePAPR mandatory cache properties.
- Add documentation concerning how we find the start of physical
memory for AUTO_ZRELADDR kernels, detailing why we have chosen the
mask and the implications of changing it.
- Updates from Ard Biesheuvel to address some issues with large
kernels (such as allyesconfig) failing to link.
- Allow hibernation to work on modern (ARMv7) CPUs - this appears to
have never worked in the past on these CPUs.
- Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output
format (hopefully without userspace breaking... let's hope that if
it causes someone a problem, they tell us.)
- Fix tegra-ahb DT offsets.
- Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/
flush_dcache_all()) code to be more efficient, and enable this
errata workaround by default for ARMv7+SMP CPUs. This complements
the Versatile Express fix above.
- Rework ARMv7 context code for errata 430973, so that only Cortex A8
CPUs are impacted by the branch target buffer flush when this
errata is enabled. Also update the help text to indicate that all
r1p* A8 CPUs are impacted.
- Switch ARM to the generic show_mem() implementation, it conveys all
the information which we were already reporting.
- Prevent slow timer sources being used for udelay() - timers running
at less than 1MHz are not useful for this, and can cause udelay()
to return immediately, without any wait. Using such a slow timer
is silly.
- VDSO support for 32-bit ARM, mainly for gettimeofday() using the
ARM architected timer.
- Perf support for Scorpion performance monitoring units"
vdso semantic conflict fixed up as per linux-next.

Pull power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes and cleanups all over, although there are a few
items that sort of fall into the new feature category.
First off, we have new callbacks for PM domains that should help us to
handle some issues related to device initialization in a better way.
There also is some consolidation in the unified device properties API
area allowing us to use that inferface for accessing data coming from
platform initialization code in addition to firmware-provided data.
We have some new device/CPU IDs in a few drivers, support for new
chips and a new cpufreq driver too.

mm: fold arch_randomize_brk into ARCH_HAS_ELF_RANDOMIZE
The arch_randomize_brk() function is used on several architectures, even those that don't support ET_DYN ASLR. To avoid bulky extern/#define tricks, consolidate the support under CONFIG_ARCH_HAS_ELF_RANDOMIZE for the architectures that support it, while still handling CONFIG_COMPAT_BRK.
