arm64: Make ARM64_ERRATUM_1188873 depend on COMPAT
Since ARM64_ERRATUM_1188873 only affects AArch32 EL0, it makes some sense that it should depend on COMPAT. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com> |

arm64: Restrict ARM64_ERRATUM_1188873 mitigation to AArch32
We currently deal with ARM64_ERRATUM_1188873 by always trapping EL0 accesses for both instruction sets. Although nothing wrong comes out of that, people trying to squeeze the last drop of performance from buggy HW find this over the top. Oh well. Let's change the mitigation by flipping the counter enable bit on return to userspace. Non-broken HW gets an extra branch on the fast path, which is hopefully not the end of the world. The arch timer workaround is also removed. Acked-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com> |

arm64: tegra: Disable CQE Support for SDMMC4 on Tegra186
Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression
that is causing accesses to the file-system on the eMMC to fail. Errors
such as the following have been observed ...
mmc2: running CQE recovery
mmc2: mmc_select_hs400 failed, error -110
print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700
mmc2: cqhci: CQE failed to exit halt state
For now disable CQE support for Tegra186 until this issue is resolved.

KVM: arm64: Reset the PMU in preemptible context
We've become very cautious to now always reset the vcpu when nothing
is loaded on the physical CPU. To do so, we now disable preemption
and do a kvm_arch_vcpu_put() to make sure we have all the state
in memory (and that it won't be loaded behind out back).
This now causes issues with resetting the PMU, which calls into perf.
Perf itself uses mutexes, which clashes with the lack of preemption.
It is worth realizing that the PMU is fully emulated, and that
no PMU state is ever loaded on the physical CPU. This means we can
perfectly reset the PMU outside of the non-preemptible section.

arm64: Add MIDR encoding for HiSilicon Taishan CPUs
Adding the MIDR encodings for HiSilicon Taishan v110 CPUs, which is used in Kunpeng ARM64 server SoCs. TSV110 is the abbreviation of Taishan v110.

arm64/stacktrace: Export save_stack_trace_regs()
The ARM64 implements the save_stack_trace_regs function, but it is
unusable for any diagnostic tooling compiled as a kernel module due
the missing EXPORT_SYMBOL_GPL for the function. Export
save_stack_trace_regs() to align with other architectures such as
s390, openrisc, and powerpc. This is similar to the ARM64 export of
save_stack_trace_tsk() added in git commit

arm64: apply workaround on A64FX v1r0
Fujitsu erratum 010001 applies to A64FX v0r0 and v1r0, and we try to
handle either by masking MIDR with MIDR_FUJITSU_ERRATUM_010001_MASK
before comparing it to MIDR_FUJITSU_ERRATUM_010001.
Unfortunately, MIDR_FUJITSU_ERRATUM_010001 is constructed incorrectly
using MIDR_VARIANT(), which is intended to extract the variant field
from MIDR_EL1, rather than generate the field in-place. This results in
MIDR_FUJITSU_ERRATUM_010001 being all-ones, and we only match A64FX
v0r0.
This patch uses MIDR_CPU_VAR_REV() to generate an in-place mask for the
variant field, ensuring the we match both v0r0 and v1r0.

kbuild: force all architectures except um to include mandatory-y
Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

This is the bulk of GPIO changes for the v5.1 cycle:
Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip. This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip support a "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough. PCA953x is the first user of this new API. - The GPIO mockup driver has been revamped after some discussion improving the IRQ simulator in the process. The idea is to make it possible to use the mockup for both testing and virtual prototyping, e.g. when you do not yet have a GPIO expander to play with but really want to get something to develop code around before hardware is available. It's neat. The blackbox testing usecase is currently making its way into kernelci. - ACPI GPIO core preserves non direction flags when updating flags. - A new device core helper for devm_platform_ioremap_resource() is funneled through the GPIO tree with Greg's ACK. New drivers: - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O) - Gateworks PLD GPIO driver (vaccumed up from OpenWrt) - AMD G-Series PCH (Platform Controller Hub) GPIO driver. - Fintek F81804 & F81966 subvariants. - PCA953x now supports NXP PCAL6416. Driver improvements: - IRQ support on the Nintendo Wii (Hollywood) GPIO. - get_direction() support for the MVEBU driver. - Set the right output level on SAMA5D2. - Drop the unused irq trigger setting on the Spreadtrum driver. - Wakeup support for PCA953x. - A slew of cleanups in the various Intel drivers. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJcgoLEAAoJEEEQszewGV1zjBAP/3OmTFGv49PFmJwSx+PlLiYf V6/UPaQzq81CGSMtHxbS51TyP9Id7PCfsacbuFYutzn0D1efvl7jrkb8qJ6fVvCM bl/i6q8ipRTPzAf1hD3QCgCe3BXCA064/OcPrz987oIvI3bJQXsmBjBSXHWr4Cwa WfB5DX/afn9TK3XHhMQGfw5f0d+TtnKAs90RTTVKiz9Ow8eFYZJOhgPkvhCR3Gi9 YJIzIAiwhHZ7/zauo4JAYFU/O/Z3YEC5zeLne2ItebzNooRkSxdz0c9Hs7HlCZmU 930Uv9jNN89N3vPqpZzAHtPvwDOmAILMWvKy9xRSp+eoIukarRJgF7ALPk7QWxK1 yy+tGj4dXBQ6tI8W3wUN1WgjNpii3K1HbJ+1LQVQL2/q9o+3YXXqmjdjuw7C8YYV 5ystNrUppkgfIIciHL4lhqw3wKJJhVEAns2V245hIitoShT+RvIg8GQbGZmWlQFd YsHbynqHL9iwfRNv26kEqZXZOo/4D1t6Scw+OPVyba2Wyttf+qbmg+XaYMqFaxYW mfydvdtymeCOUIPJMzw58KGPUTXJ4UPLENyayXNUHokr1a8VO8OIthY7zwi0CpvJ IcsAY9zoGxvfbRV922mlIsw3oOBcM2IN2lC9sY469ZVnjBrdC3rsQpIBZr+Vzz8i YlUfXLSGSyuUZUz//2eG =VoVC -----END PGP SIGNATURE----- Merge tag 'gpio-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.1 cycle: Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip.

ARM: New SoC family support
Two new SoC families are added this time. Sugaya Taichi submitted support for the Milbeaut SoC family from Socionext and explains: "SC2000 is a SoC of the Milbeaut series. equipped with a DSP optimized for computer vision. It also features advanced functionalities such as 360-degree, real-time spherical stitching with multi cameras, image stabilization for without mechanical gimbals, and rolling shutter correction. More detail is below: https://www.socionext.com/en/products/assp/milbeaut/SC2000.html" Interestingly, this one has a history dating back to older chips made by Socionext and previously Matsushita/Panasonic based on their own mn10300 CPU architecture that was removed from the kernel last year. Manivannan Sadhasivam adds support for another SoC family, this is the Bitmain BM1880 chip used in the Sophon Edge TPU developer board. The chip is intended for Deep Learning applications, and comes with dual-core Arm Cortex-A53 to run Linux as well as a RISC-V microcontroller core to control the tensor unit. For the moment, the TPU is not accessible in mainline Linux, so we treat it as a generic Arm SoC.

ARM: SoC platform updates for 5.1
The APM X-Gene platform is now maintained by folks from Ampere computing that took over the product line a while ago, this gets reflected in the MAINTAINERS file. Cleanups continue on the older mach-davinci and mach-pxa platform, to get them to be more like the modern ones. For pxa, we now remove the Raumfeld platform code as it now works with device tree based booting. i.MX adds a couple new features for the i.MX7ULP SoC Mediatek gains support for a new SoC: MT7629 is a new wireless router platform, following MT7623.

Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar: "The biggest part of this tree is the new auto-generated atomics API wrappers by Mark Rutland. The primary motivation was to allow instrumentation without uglifying the primary source code. The linecount increase comes from adding the auto-generated files to the Git space as well: include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++-- include/asm-generic/atomic-long.h | 1174 ++++++++++--- include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++ include/linux/atomic.h | 1241 +------------ I preferred this approach, so that the full call stack of the (already complex) locking APIs is still fully visible in 'git grep'. But if this is excessive we could certainly hide them. There's a separate build-time mechanism to determine whether the headers are out of date (they should never be stale if we do our job right). Anyway, nothing from this should be visible to regular kernel developers. Other changes: - Add support for dynamic keys, which removes a source of false positives in the workqueue code, among other things (Bart Van Assche) - Updates to tools/memory-model (Andrea Parri, Paul E.

arm64: kdump: no need to mark crashkernel pages manually PG_reserved
The crashkernel is reserved via memblock_reserve(). memblock_free_all() will call free_low_memory_core_early(), which will go over all reserved memblocks, marking the pages as PG_reserved. So manually marking pages as PG_reserved is not necessary, they are already in the desired state (otherwise they would have been handed over to the buddy as free pages and bad things would happen).

arm64/mm: enable HugeTLB migration for contiguous bit HugeTLB pages
Let arm64 subscribe to the previously added framework in which architecture can inform whether a given huge page size is supported for migration. This just overrides the default function arch_hugetlb_migration_supported() and enables migration for all possible HugeTLB page sizes on arm64. With this, HugeTLB migration support on arm64 now covers all possible HugeTLB options.

kasan: remove use after scope bugs detection.
Use after scope bugs detector seems to be almost entirely useless for the linux kernel. It exists over two years, but I've seen only one valid bug so far [1]. And the bug was fixed before it has been reported. There were some other use-after-scope reports, but they were false-positives due to different reasons like incompatibility with structleak plugin. This feature significantly increases stack usage, especially with GCC < 9 version, and causes a 32K stack overflow. It probably adds performance penalty too. Given all that, let's remove use-after-scope detector entirely. While preparing this patch I've noticed that we mistakenly enable use-after-scope detection for clang compiler regardless of CONFIG_KASAN_EXTRA setting. This is also fixed now.
