Merge tag 'riscv-for-linus-6.14-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt: - The PH1520 pinctrl and dwmac drivers are enabeled in defconfig - A redundant AQRL barrier has been removed from the futex cmpxchg implementation - Support for the T-Head vector extensions, which includes exposing these extensions to userspace on systems that implement them - Some more page table information is now printed on die() and systems that cause PA overflows * tag 'riscv-for-linus-6.14-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: add a warning when physical memory address overflows riscv/mm/fault: add show_pte() before die() riscv: Add ghostwrite vulnerability selftests: riscv: Support xtheadvector in vector tests selftests: riscv: Fix vector tests riscv: hwprobe: Document thead vendor extensions and xtheadvector extension riscv: hwprobe: Add thead vendor extension probing riscv: vector: Support xtheadvector save/restore riscv: Add xtheadvector instruction definitions riscv: csr: Add CSR encodings for CSR_VXRM/CSR_VXSAT RISC-V: define the elements of the VCSR vector CSR riscv: vector: Use vlenb from DT for thead riscv: Add thead and xtheadvector as a vendor extension riscv: dts: allwinner: Add xtheadvector to the D1/D1s devicetree dt-bindings: cpus: add a thead vlen register length property dt-bindings: riscv: Add xtheadvector ISA extension description RISC-V: Mark riscv_v_init() as __init riscv: defconfig: drop RT_GROUP_SCHED=y riscv/futex: Optimize atomic cmpxchg riscv: defconfig: enable pinctrl and dwmac support for TH1520
