arm64: KVM: Kill HYP_PAGE_OFFSET
HYP_PAGE_OFFSET is not massively useful. And the way we use it in KERN_HYP_VA is inconsistent with the equivalent operation in EL2, where we use a mask instead. Let's replace the uses of HYP_PAGE_OFFSET with HYP_PAGE_OFFSET_MASK, and get rid of the pointless macro.

arm64: KVM: Always reference __hyp_panic_string via its kernel VA
__hyp_panic_string is passed via the HYP panic code to the panic function, and is being "upgraded" to a kernel address, as it is referenced by the HYP code (in a PC-relative way). This is a bit silly, and we'd be better off obtaining the kernel address and not mess with it at all. This patch implements this with a tiny bit of asm glue, by forcing the string pointer to be read from the literal pool.

KVM: arm/arm64: The GIC is dead, long live the GIC
I don't think any single piece of the KVM/ARM code ever generated as much hatred as the GIC emulation. It was written by someone who had zero experience in modeling hardware (me), was riddled with design flaws, should have been scrapped and rewritten from scratch long before having a remote chance of reaching mainline, and yet we supported it for a good three years. No need to mention the names of those who suffered, the git log is singing their praises. Thankfully, we now have a much more maintainable implementation, and we can safely put the grumpy old GIC to rest. Fellow hackers, please raise your glass in memory of the GIC: The GIC is dead, long live the GIC!

arm/arm64: KVM: Map the HYP text as read-only
There should be no reason for mapping the HYP text read/write.

arm/arm64: KVM: Enforce HYP read-only mapping of the kernel's rodata section
In order to be able to use C code in HYP, we're now mapping the kernel's rodata in HYP. It works absolutely fine, except that we're mapping it RWX, which is not what it should be. Add a new HYP_PAGE_RO protection, and pass it as the protection flags when mapping the rodata section.

Currently, create_hyp_mappings applies a "one size fits all" page protection (PAGE_HYP).

arm64: KVM: vgic-v3: Relax synchronization when SRE==1
The GICv3 backend of the vgic is quite barrier heavy, in order to ensure synchronization of the system registers and the memory mapped view for a potential GICv2 guest. But when the guest is using a GICv3 model, there is absolutely no need to execute all these heavy barriers, and it is actually beneficial to avoid them altogether. This patch makes the synchonization conditional, and ensures that we do not change the EL1 SRE settings if we do not need to.

arm64: KVM: vgic-v3: Prevent the guest from messing with ICC_SRE_EL1
Both our GIC emulations are "strict", in the sense that we either emulate a GICv2 or a GICv3, and not a GICv3 with GICv2 legacy support. But when running on a GICv3 host, we still allow the guest to tinker with the ICC_SRE_EL1 register during its time slice: it can switch SRE off, observe that it is off, and yet on the next world switch, find the SRE bit to be set again. Not very nice. An obvious solution is to always trap accesses to ICC_SRE_EL1 (by clearing ICC_SRE_EL2.Enable), and to let the handler return the programmed value on a read, or ignore the write. That way, the guest can always observe that our GICv3 is SRE==1 only.

KVM: arm/arm64: vgic-new: Synchronize changes to active state
When modifying the active state of an interrupt via the MMIO interface, we should ensure that the write has the intended effect. If a guest sets an interrupt to active, but that interrupt is already flushed into a list register on a running VCPU, then that VCPU will write the active state back into the struct vgic_irq upon returning from the guest and syncing its state. This is a non-benign race, because the guest can observe that an interrupt is not active, and it can have a reasonable expectations that other VCPUs will not ack any IRQs, and then set the state to active, and expect it to stay that way. Currently we are not honoring this case. Thefore, change both the SACTIVE and CACTIVE mmio handlers to stop the world, change the irq state, potentially queue the irq if we're setting it to active, and then continue. We take this chance to slightly optimize these functions by not stopping the world when touching private interrupts where there is inherently no possible race.

KVM: arm/arm64: vgic-new: enable build
Now that the new VGIC implementation has reached feature parity with the old one, add the new files to the build system and add a Kconfig option to switch between the two versions. We set the default to the new version to get maximum test coverage, in case people experience problems they can switch back to the old behaviour if needed.

- Use 'cpu-clock' for cpu targets in 'perf stat' (Namhyung Kim)
- Avoid fractional digits for integer scales in 'perf stat' (Andi Kleen)
- Store vdso buildid unconditionally, as it appears in callchains and

end up not being able to resolve VDSO symbols when doing analysis
on a different machine than the one where recording was done, possibly
of a different arch even (arm -> x86_64) (He Kuang)
Infrastructure:

arch: fix has_transparent_hugepage()
I've just discovered that the useful-sounding has_transparent_hugepage() is actually an architecture-dependent minefield: on some arches it only builds if CONFIG_TRANSPARENT_HUGEPAGE=y, on others it's also there when not, but on some of those (arm and arm64) it then gives the wrong answer; and on mips alone it's marked __init, which would crash if called later (but so far it has not been called later). Straighten this out: make it available to all configs, with a sensible default in asm-generic/pgtable.h, removing its definitions from those arches (arc, arm, arm64, sparc, tile) which are served by the default, adding #define has_transparent_hugepage has_transparent_hugepage to those (mips, powerpc, s390, x86) which need to override the default at runtime, and removing the __init from mips (but maybe that kind of code should be avoided after init: set a static variable the first time it's called).

ARM: 64-bit DT updates for v4.7
We continue ramping up platform support for 64-bit ARM machines, with 111 individual non-merge changesets touching 21 platforms. The LG1312 platform is completely new and is the first ARM platform by LG that we support in the mainline kernel. Two other SoCs got added that are updated versions of existing SoC families, so the port mainly consists of new dts files: - The Hisilicon Hip06/D03 is the latest server platform from Huawei/Hisilicon, and follows the Hip05/D02 platform. - Rockchip RK3399 follows the 32-bit RK3288 that is popular in low-end Chromebooks and the 64-bit RK3368 that is mainly found in chinese Android TV boxes. The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a long-awaited overhaul with a lot of devices enabled in the DT, so it should be much more usable with a mainline kernel now. See also https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd A lot of work went into enabling new device drivers on existing machines, but we also have a couple of new commercially available machines: - Google Pixel C laptop based on Tegra210 - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905) - Geekbuying GeekBox based on Rockchip RK3368 And finally, a couple of reference or development platforms that are not end-user platforms but are used for trying out the respective SoC platforms: - Amlogic Meson GXBB P200 and P201 development systems - NXP Layerscape 1043A QDS development board - Hisilicon Hip06 D03 server board, as mentioned above - LG1312 Reference Design - RK3399 Evaluation Board -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXimCrR//JCVInAQJtoRAAkiyHJCwsc7UJuaPY4XyFR3JGvjRrk4vA EvpnFsfu4Xgso3yillZUY3i0oUAFAUslYJR5ycNS63OV8+CafpzVCxZmXl6N7muF +NzVsrcEBZvfX3YWRSEB6qwILqjRTNBDqDVfZEhcP3Jh7XJ1U+TPcTKGMuG0zRVL NvGbEM0YF21kKJXz8rPWx/moYhNmE/1E5XEI5e5NpoO9y9BIRjJPSkpkstccaO5I Hvd2cqa8sHLROY0ffhK+UNytvSqvkTILUswlBBFC+/JX4yctFeLTcEbLrEpGnWUG zqy6lIooq2IBKKDsrxTisIZ5ACwoLQlMUdBRUYgNkjH5KR7/DBmUQO2WygYGb/xC imLiJpIIshkBG/xFrSVJjVDleTW++CecHU8uFVQaftOl1EHFGEs8ChCooRk9lRMq jQyEEGbX33dKUlGSvkMiVIufWOFBL+AqefFgl+TPDZf0xXWoFGA4cOvdxClxKSF5 Eh6XnQu9mQLHQ3OjetuQE+VsZHEKoe+cIH2ypUj4D4MJAWV6ok6bsbQJtMmLgwbZ fh1pHSpCHG3iJqaoICFmcokiymiLst3lZqOm6GP4Glgbs8TVwKfeYNUSFRVMlJ5W BQ/SVaBuXbAiv8Ree7wk2HbAXtOzKuFqEzVVRWd3XgIERTbNZaI+qoFssh0TIlBe WNDmLB+6E5Q= =locI -----END PGP SIGNATURE----- Merge tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM 64-bit DT updates from Arnd Bergmann: "We continue ramping up platform support for 64-bit ARM machines, with 111 individual non-merge changesets touching 21 platforms.

ARM: DT updates for v4.7
These are all the updates to device tree files for 32-bit platforms,
which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
changesets, 450 files changed, 23340 insertions, 5216 deletions.
The three platforms that are added with the "soc" branch are here as well,
and we add some related machine files:
- For Aspeed AST2400/AST2500, we get the evaluation platform and
the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
- For Oxnas 810SE, the Western Digital "My Book World Edition"
is added as the only platform at the moment.
- For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
are supported
On the ARM Realview development platform, we now support all machines
with device tree, previously only the board files were supported, which
in turn will likely be removed soon.
Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",

bpf: arm64: remove callee-save registers use for tmp registers
In the current implementation of ARM64 eBPF JIT, R23 and R24 are used for tmp registers, which are callee-saved registers. This leads to variable size of JIT prologue and epilogue. The latest blinding constant change prefers to constant size of prologue and epilogue. AAPCS reserves R9 ~ R15 for temp registers which not need to be saved/restored during function call. So, replace R23 and R24 to R10 and R11, and remove tmp_used flag to save 2 instructions for some jited BPF program.

ACPI material for v4.7-rc1
- In-kernel ACPICA code update to the upstream release 20160422
adding support for ACPI 6.1 along with some previously missing
bits of ACPI 6.0 support, making a fair amount of fixes and
cleanups and reducing divergences between the upstream ACPICA
and the in-kernel code (Bob Moore, Lv Zheng, Al Stone, Aleksey
Makarov, Will Miles).
- ACPI Generic Event Device (GED) support and a fix for it (Sinan Kaya,
Paul Gortmaker).
- INT3406 thermal driver for display thermal management and ACPI
backlight support code reorganization related to it (Aaron Lu,
Arnd Bergmann).
- Support for exporting the value returned by the _HRV (hardware
revision) ACPI object via sysfs (Betty Dall).
- Removal of the EXPERT dependency for ACPI on ARM64 (Mark Brown).
- Rework of the handling of ACPI _OSI mechanism allowing the
_OSI("Darwin") support to be overridden from the kernel command
line among other things (Lv Zheng, Chen Yu).
- Rework of the ACPI tables override mechanism to prepare it for
the introduction of overlays support going forward (Lv Zheng,
Rafael Wysocki).
- Fixes related to the ECDT support and module-level execution
of AML (Lv Zheng).
- ACPI PCI interrupts management update to make it work better on
ARM64 mostly (Sinan Kaya).
- ACPI SRAT handling update to make the code process all entires
in the table order regardless of the entry type (Lukasz Anaczkowski).
- EFI power off support for full-hardware ACPI platforms that don't
support ACPI S5 (Chen Yu).
- Fixes and cleanups related to the ACPI core's sysfs interface
(Dan Carpenter, Betty Dall).

Pull ACPI updates from Rafael Wysocki:
"The new features here are ACPI 6.1 support (and some previously
missing bits of ACPI 6.0 support) in ACPICA and two new drivers, a
driver for the ACPI Generic Event Device (GED) feature introduced by
ACPI 6.1 and the INT3406 thermal driver for display thermal
management. Also the value returned by the _HRV (hardware revision)
ACPI object will be exported to user space via sysfs now.
In addition to that, ACPI on ARM64 will not depend on EXPERT any more.
The rest is mostly fixes and cleanups and some code reorganization.
Specifics:
- In-kernel ACPICA code update to the upstream release 20160422
adding support for ACPI 6.1 along with some previously missing bits
of ACPI 6.0 support, making a fair amount of fixes and cleanups and
reducing divergences between the upstream ACPICA and the in-kernel
code (Bob Moore, Lv Zheng, Al Stone, Aleksey Makarov, Will Miles)
- ACPI Generic Event Device (GED) support and a fix for it (Sinan
Kaya, Paul Gortmaker)
- INT3406 thermal driver for display thermal management and ACPI
backlight support code reorganization related to it (Aaron Lu, Arnd
Bergmann)
- Support for exporting the value returned by the _HRV (hardware
revision) ACPI object via sysfs (Betty Dall)
- Removal of the EXPERT dependency for ACPI on ARM64 (Mark Brown)
- Rework of the handling of ACPI _OSI mechanism allowing the
_OSI("Darwin") support to be overridden from the kernel command
line among other things (Lv Zheng, Chen Yu)
- Rework of the ACPI tables override mechanism to prepare it for the
introduction of overlays support going forward (Lv Zheng, Rafael
Wysocki)
- Fixes related to the ECDT support and module-level execution of AML
(Lv Zheng)
- ACPI PCI interrupts management update to make it work better on
ARM64 mostly (Sinan Kaya)
- ACPI SRAT handling update to make the code process all entires in
the table order regardless of the entry type (Lukasz Anaczkowski)
- EFI power off support for full-hardware ACPI platforms that don't
support ACPI S5 (Chen Yu)
- Fixes and cleanups related to the ACPI core's sysfs interface (Dan
Carpenter, Betty Dall)
- acpi_dev_present() API rework to reduce possible confusion related
to it (Lukas Wunner)
- Removal of CLK_IS_ROOT from two ACPI drivers (Stephen Boyd)"

perf core: Add a 'nr' field to perf_event_callchain_context
We will use it to count how many addresses are in the entry->ip[] array,
excluding PERF_CONTEXT_{KERNEL,USER,etc} entries, so that we can really
return the number of entries specified by the user via the relevant
sysctl, kernel.perf_event_max_contexts, or via the per event
perf_event_attr.sample_max_stack knob.
This way we keep the perf_sample->ip_callchain->nr meaning, that is the
number of entries, be it real addresses or PERF_CONTEXT_ entries, while
honouring the max_stack knobs, i.e. the end result will be max_stack
entries if we have at least that many entries in a given stack trace.

bpf, arm64: add support for constant blinding
This patch adds recently added constant blinding helpers into the arm64 eBPF JIT. In the bpf_int_jit_compile() path, requirements are to utilize bpf_jit_blind_constants()/bpf_jit_prog_release_other() pair for rewriting the program into a blinded one, and to map the BPF_REG_AX register to a CPU register. The mapping is on x9.

bpf: prepare bpf_int_jit_compile/bpf_prog_select_runtime apis
Since the blinding is strictly only called from inside eBPF JITs, we need to change signatures for bpf_int_jit_compile() and bpf_prog_select_runtime() first in order to prepare that the eBPF program we're dealing with can change underneath. Hence, for call sites, we need to return the latest prog. No functional change in this patch.

bpf, x86/arm64: remove useless checks on prog
There is never such a situation, where bpf_int_jit_compile() is called with either prog as NULL or len as 0, so the tests are unnecessary and confusing as people would just copy them. s390 doesn't have them, so no change is needed there.
