ARM/PCI: Remove msi_controller from struct pci_sys_data
ARM now uses pci_bus->msi to store the msi_controller pointer, so we don't need to save it in struct pci_sys_data, and we don't need to implement pcibios_msi_controller() to get it out of pci_sys_data. Remove msi_controller from struct pci_sys_data and pcibios_msi_controller().

ARM/PCI, designware, xilinx: Use pci_scan_root_bus_msi()
ARM previously stored the msi_controller pointer in its sysdata, struct pci_sys_data, and implemented pcibios_msi_controller() to retrieve it. That made PCI host controller drivers specific to ARM because they had to put the msi_controller pointer in the ARM-specific pci_sys_data. There is now a generic mechanism, pci_scan_root_bus_msi(), for giving the msi_controller pointer to the PCI core. Use this for all ARM systems and for the DesignWare and Xilinx PCI host controller drivers. This removes an ARM dependency from the DesignWare, DRA7xx, EXYNOS, i.MX6, Keystone, Layerscape, SPEAr13xx, and Xilinx drivers.

The i.MX SoC changes for 4.3:
- Add i.MX6 Ultralite SoC support, which is the newest addition to
i.MX6 family. It integrates a single Cortex-A7 core and a power
management module that reduces the complexity of external power
supply and simplifies power sequencing.
- Change SNVS RTC driver to use syscon interface for register access,
and add SNVS power key driver support.
- Add a second clock for mxc rtc driver, and support device tree probe
for the driver.
- Add FEC MAC reference clock and phy fixup initialization for i.MX6UL
platform.

ARM: avoid unwanted GCC memset()/memcpy() optimisations for IO variants
We don't want GCC optimising our memset_io(), memcpy_fromio() or memcpy_toio() variants, so we must not call one of the standard functions. Provide a separate name for our assembly memcpy() and memset() functions, and use that instead, thereby bypassing GCC's ability to optimise these operations. GCCs optimisation may introduce unaligned accesses which are invalid for device mappings. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |

ARM: io: convert ioremap*() to functions
Convert the ioremap*() preprocessor macros to real functions, moving them out of line. This allows us to kill off __arm_ioremap(), and __arm_iounmap() helpers, and remove __arm_ioremap_pfn_caller() from global view. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |

ARM: io: fix ioremap_wt() implementation
ioremap_wt() was added by aliasing it to ioremap_nocache(), which is a device mapping. Device mappings do not allow unaligned accesses, but it appears that GCC is able to inline its own memcpy() implementation which may use such accesses. The only user of this is pmem, which uses memcpy() on the region. Therefore, this is unsafe. We must implement ioremap_wt() correctly for ARM, or not at all. This patch adds a more correct implementation by re-using ioremap_wc() to provide a normal-memory non-cacheable mapping. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |

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 tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"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
- Fix 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"

ARM: 8389/1: Add cpu_resume_arm() for firmwares that resume in ARM state
Some platforms always enter the kernel in the ARM state even if the kernel is compiled for THUMB2. Add a small wrapper on top of cpu_resume() that switches into THUMB2 state. 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. (rmk: tweaked to work without BSYM->badr changes.)

arm64: KVM: Switch vgic save/restore to alternative_insn
So far, we configured the world-switch by having a small array of pointers to the save and restore functions, depending on the GIC used on the platform. Loading these values each time is a bit silly (they never change), and it makes sense to rely on the instruction patching instead. This leads to a nice cleanup of the code.

The i.MX SoC updates for 4.2:
- Add new SoC i.MX7D support, which integrates two Cortex-A7 and one
Cortex-M4 cores.
- Support suspend from IRAM on i.MX53, so that DDR pins can be set to
high impedance for more power saving during suspend.
- Move i.MX clock drivers from arch/arm/mach-imx to drivers/clk/imx.
- Move i.MX GPT timer driver from arch/arm/mach-imx into
drivers/clocksource.
- A couple of clock driver update for VF610 and i.MX6Q.
- A few random code correction and improvement.
