Linus Torvalds 4a1d8ababd RISC-V Patches for the 6.15 Merge Window, Part 1
* 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.
