2021-03-30arm64: dts: intel: socfpga_agilex: move timer out of soc nodeKrzysztof Kozlowski1-9/+9
The ARM architected timer is part of ARM CPU design therefore by convention it should not be inside the soc node. This also fixes dtc warning like: arch/arm64/boot/dts/intel/socfpga_agilex.dtsi:410.9-416.5: Warning (simple_bus_reg): /soc/timer: missing or empty reg/ranges property Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
2021-03-30arm64: dts: intel: socfpga_agilex: move clocks out of soc nodeKrzysztof Kozlowski1-28/+28
The clocks are usually not part of the SoC but provided on the board (external oscillators). Moving them out of soc node fixes dtc warning: arch/arm64/boot/dts/intel/socfpga_agilex.dtsi:111.10-137.5: Warning (simple_bus_reg): /soc/clocks: missing or empty reg/ranges property Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
2021-03-30arm64: dts: intel: socfpga: override clocks by labelKrzysztof Kozlowski3-24/+12
Using full paths to extend or override a device tree node is error prone. If there was a typo error, a new node will be created instead of extending the existing node. This will lead to run-time errors that could be hard to detect. A mistyped label on the other hand, will cause a dtc compile error (during build time).

2021-03-30riscv: Cleanup KASAN_VMALLOC supportAlexandre Ghiti1-41/+18
When KASAN vmalloc region is populated, there is no userspace process and the page table in use is swapper_pg_dir, so there is no need to read SATP. Then we can use the same scheme used by kasan_populate_p*d functions to go through the page table, which harmonizes the code. In addition, make use of set_pgd that goes through all unused page table levels, contrary to p*d_populate functions, which makes this function work whatever the number of page table levels.

If a uaccess (e.g. get_user()) triggers a fault and there's a fault signal pending, the handler will return to the uaccess without having performed a uaccess fault fixup, and so the CPU will immediately execute the uaccess instruction again, whereupon it will livelock bouncing between that instruction and the fault handler. https://lore.kernel.org/lkml/20210121123140.GD48431@C02TD0UTHF1T.local/ Cc: stable@vger.kernel.org Reported-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

Apparently, on the affected system, the ACPI table in question is not located in "reserved" memory, like ACPI NVS or ACPI Data, that will not be used by the buddy allocator, so the memory occupied by that table has to be explicitly reserved to prevent the buddy allocator from using it. In order to address this problem, rearrange the initialization of the ACPI tables on x86 to locate the initial tables earlier and reserve the memory occupied by them. The other architectures using ACPI should not be affected by this change.

2021-03-29arm64: Kconfig: select KASAN_VMALLOC if KANSAN_GENERIC is enabledLecopzer Chen1-0/+1
Before this patch, someone who wants to use VMAP_STACK when KASAN_GENERIC enabled must explicitly select KASAN_VMALLOC. >From Will's suggestion [1]: > I would _really_ like to move to VMAP stack unconditionally, and > that would effectively force KASAN_VMALLOC to be set if KASAN is in use Because VMAP_STACK now depends on either HW_TAGS or KASAN_VMALLOC if KASAN enabled, in order to make VMAP_STACK selected unconditionally, we bind KANSAN_GENERIC and KASAN_VMALLOC together. Note that SW_TAGS supports neither VMAP_STACK nor KASAN_VMALLOC now, so this is the first step to make VMAP_STACK selected unconditionally. Bind KANSAN_GENERIC and KASAN_VMALLOC together is supposed to cost more memory at runtime, thus the alternative is using SW_TAGS KASAN instead.

Arm64 provides defined macro for KERNEL_START and KERNEL_END, thus replace them by the abstration instead of using _text and _end.

2021-03-29arm64: kasan: don't populate vmalloc area for CONFIG_KASAN_VMALLOCLecopzer Chen1-5/+14
Linux support KAsan for VMALLOC since commit 3c5c3cfb9ef4da9 ("kasan: support backing vmalloc space with real shadow memory") Like how the MODULES_VADDR does now, just not to early populate the VMALLOC_START between VMALLOC_END. Before: MODULE_VADDR: no mapping, no zero shadow at init VMALLOC_VADDR: backed with zero shadow at init After: MODULE_VADDR: no mapping, no zero shadow at init VMALLOC_VADDR: no mapping, no zero shadow at init Thus the mapping will get allocated on demand by the core function of KASAN_VMALLOC. ----------- vmalloc_shadow_start | | | | | | <= non-mapping | | | | |-----------| |///////////|<- kimage shadow with page table mapping. |-----------| | | | | <= non-mapping | | ------------- vmalloc_shadow_end |00000000000| |00000000000| <= Zero shadow |00000000000| ------------- KASAN_SHADOW_END Signed-off-by: Lecopzer Chen <lecopzer.chen@mediatek.com> Acked-by: Andrey Konovalov <andreyknvl@gmail.com> Tested-by: Andrey Konovalov <andreyknvl@gmail.com> Tested-by: Ard Biesheuvel <ardb@kernel.org> Link: https://lore.kernel.org/r/20210324040522.15548-2-lecopzer.chen@mediatek.com [catalin.marinas@arm.com: add a build check on VMALLOC_START != MODULES_END] Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2021-03-29arm64: smp: Add missing prototype for some smp.c functionsChen Lifu2-0/+3
In commit eb631bb5bf5b ("arm64: Support arch_irq_work_raise() via self IPIs") a new function "arch_irq_work_raise" was added without a prototype. In commit d914d4d49745 ("arm64: Implement panic_smp_self_stop()") a new function "panic_smp_self_stop" was added without a prototype. We get the following warnings on W=1: arch/arm64/kernel/smp.c:842:6: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes] arch/arm64/kernel/smp.c:862:6: warning: no previous prototype for ‘panic_smp_self_stop’ [-Wmissing-prototypes] Fix the warnings by: 1. Adding the prototype for 'arch_irq_work_raise' in irq_work.h 2.
