2022-03-05ARM: dts: rockchip: Add #clock-cells value for rk805Chris Morgan
Based on a brief discussion on the mailing list it was determined that clock-cells should be a required parameter in the event that a consumer of the clock gets added in an overlay.

2022-03-04ARM: dts: at91: sama7g5: Add NAND supportTudor Ambarus
Add NAND support. The sama7g5's SMC IP is the same as sama5d2's with a slightly change: it provides a synchronous clock output (SMC clock) that is dedicated to FPGA usage. Since this doesn't interfere with the SMC NAND configuration, thus code will not be added in the current nand driver to address the FPGA usage, use the sama5d2's compatible and choose not to introduce dedicated compatibles for sama7g5. Tested with Micron MT29F4G08ABAEAWP NAND flash.

2022-03-03dma-mapping: remove CONFIG_DMA_REMAPChristoph Hellwig
CONFIG_DMA_REMAP is used to build a few helpers around the core vmalloc code, and to use them in case there is a highmem page in dma-direct, and to make dma coherent allocations be able to use non-contiguous pages allocations for DMA allocations in the dma-iommu layer. Right now it needs to be explicitly selected by architectures, and is only done so by architectures that require remapping to deal with devices that are not DMA coherent. Make it unconditional for builds with CONFIG_MMU as it is very little extra code, but makes it much more likely that large DMA allocations succeed on x86. This fixes hot plugging a NVMe thunderbolt SSD for me, which tries to allocate a 1MB buffer that is otherwise hard to obtain due to memory fragmentation on a heavily used laptop.

2022-03-01Merge tag 'qcom-drivers-for-5.18' of ↵Arnd Bergmann
git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.18 This refactors the Qualcomm mdt file loader, to partially decouple it from the SCM peripheral-authentication-service. This is needed as newer platforms, such as the Qualcomm SM8450, require the metadata to remain accessible to TrustZone during a longer time. This is followed by the introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1). It changes the way hardware version differences are handled in the LLCC driver and introduces support for Qualcomm SM8450. While updating the dt binding for LLCC it also introduces the missing SM8350 compatible. The ocmem and aoss drivers gains missing put_device() calls and rpmpd gains a missing check for kcalloc() failure. The SPM driver is updated to avoid instantiating the SPM cpuidle devices if the CPUs aren't controlled by SPM, such as when Snapdragon 8916 operates in 32-bit mode without PSCI. The RPM power-domain driver gains MSM8226 support. Lastly the socinfo driver gains knowledge about a few new SoCs and PMICs. * tag 'qcom-drivers-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (37 commits) soc: qcom: rpmpd: Add MSM8226 support dt-bindings: power: rpmpd: Add MSM8226 to rpmpd binding soc: qcom: mdt_loader: Fix split-firmware condition dt-bindings: arm: msm: Add LLCC compatible for SM8450 dt-bindings: arm: msm: Add LLCC compatible for SM8350 soc: qcom: llcc: Add configuration data for SM8450 SoC soc: qcom: llcc: Update register offsets for newer LLCC HW soc: qcom: llcc: Add missing llcc configuration data soc: qcom: llcc: Add write-cache cacheable support soc: qcom: llcc: Update the logic for version info extraction soc: qcom: llcc: Add support for 16 ways of allocation soc: qcom: socinfo: Add some more PMICs and SoCs firmware: qcom: scm: Add support for MC boot address API firmware: qcom: scm: Drop cpumask parameter from set_boot_addr() firmware: qcom: scm: Simplify set_cold/warm_boot_addr() cpuidle: qcom-spm: Check if any CPU is managed by SPM remoteproc: qcom: pas: Add SM8450 remoteproc support dt-bindings: remoteproc: qcom: pas: Add SM8450 PAS compatibles remoteproc: qcom: pas: Carry PAS metadata context soc: qcom: mdt_loader: Extract PAS operations ...

2022-02-28ARM: pxa: remove Intel Imote2 and Stargate 2 boardsJonathan Cameron
I have no reason to believe these boards have any more users and I haven't tested them for several years. Removing them may simplify other changes to the various PXA boards people still care about. The recent conversion of pxa2xx_spi to GPIO descriptors for example had to update this board despite no one caring or testing. Great boards that got me started in kernel development, RIP!

2022-02-28ARM: 9181/1: vdso: remove -nostdlib compiler flagMasahiro Yamada
The -nostdlib option requests the compiler to not use the standard system startup files or libraries when linking. It is effective only when $(CC) is used as a linker driver. Since commit fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to link VDSO"), $(LD) is directly used, hence -nostdlib is unneeded.

2022-02-25usercopy: Check valid lifetime via stack depthKees Cook
One of the things that CONFIG_HARDENED_USERCOPY sanity-checks is whether an object that is about to be copied to/from userspace is overlapping the stack at all. If it is, it performs a number of inexpensive bounds checks. One of the finer-grained checks is whether an object crosses stack frames within the stack region. Doing this on x86 with CONFIG_FRAME_POINTER was cheap/easy. Doing it with ORC was deemed too heavy, and was left out (a while ago), leaving the courser whole-stack check. The LKDTM tests USERCOPY_STACK_FRAME_TO and USERCOPY_STACK_FRAME_FROM try to exercise these cross-frame cases to validate the defense is working. They have been failing ever since ORC was added (which was expected). While Muhammad was investigating various LKDTM failures[1], he asked me for additional details on them, and I realized that when exact stack frame boundary checking is not available (i.e. everything except x86 with FRAME_POINTER), it could check if a stack object is at least "current depth valid", in the sense that any object within the stack region but not between start-of-stack and current_stack_pointer should be considered unavailable (i.e. its lifetime is from a call no longer present on the stack). Introduce ARCH_HAS_CURRENT_STACK_POINTER to track which architectures have actually implemented the common global register alias. Additionally report usercopy bounds checking failures with an offset from current_stack_pointer, which may assist with diagnosing failures. The LKDTM USERCOPY_STACK_FRAME_TO and USERCOPY_STACK_FRAME_FROM tests (once slightly adjusted in a separate patch) pass again with this fixed.
