Merge tag 'riscv-for-linus-6.15-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - The sub-architecture selection Kconfig system has been cleaned up,
   the documentation has been improved, and various detections have been
   fixed

 - The vector-related extensions dependencies are now validated when
   parsing from device tree and in the DT bindings

 - Misaligned access probing can be overridden via a kernel command-line
   parameter, along with various fixes to misalign access handling

 - Support for relocatable !MMU kernels builds

 - Support for hpge pfnmaps, which should improve TLB utilization

 - Support for runtime constants, which improves the d_hash()
   performance

 - Support for bfloat16, Zicbom, Zaamo, Zalrsc, Zicntr, Zihpm

 - Various fixes, including:
      - We were missing a secondary mmu notifier call when flushing the
        tlb which is required for IOMMU
      - Fix ftrace panics by saving the registers as expected by ftrace
      - Fix a couple of stimecmp usage related to cpu hotplug
      - purgatory_start is now aligned as per the STVEC requirements
      - A fix for hugetlb when calculating the size of non-present PTEs
