    Pull RISC-V fixes from Paul Walmsley:
     "Relatively low-impact fixes. Probably the most notable one is that we
      no longer ask the monitor-mode firmware to delegate misaligned access
      handling to the kernel by default, since the kernel code needs
      significant improvement to match the functionality of the firmware.
      This change avoids functional problems at some cost in performance,
      but shouldn't affect any system with misaligned access handling in
      hardware.

       - Disable satp register probing when no5lvl is specified on the
         kernel command line

       - Fix a CFI-related issue with the misaligned access speed
         measurement code

       - Reduce the CFI shadow stack size limit from 4GB to 2GB (following
         ARM64 GCS)

       - Prevent the kernel from requesting delegation of misaligned access
         faults unless a new Kconfig option, RISCV_SBI_FWFT_DELEGATE_MISALIGNED,
         is enabled. This will depend on CONFIG_NONPORTABLE until the
         deficiencies of the kernel misaligned access fixup code are fixed

       - Fix some potential uninitialized memory accesses in error paths in
         compat_riscv_gpr_set() and compat_restore_sigcontext()

       - Fix a bug in the RISC-V MIPS vendor errata patching code where a
         logical-and was used in place of a bitwise-and

       - Drop some unnecessary code in riscv_fill_hwcap_from_isa_string()

       - Use macros for isa2hwcap indices in riscv_fill_hwcap(), rather than
         open-coding them

       - Fix some documentation typos (one affecting 'make htmldocs')"
