    Pull RISC-V fixes from Paul Walmsley:
     "The most notable change involves the rseq kselftest common Makefile
      (as it is not RISC-V-specific). The basic approach in the patch
      appears similar to one used in the KVM and S390 selftests (grep for
      LINUX_TOOL_ARCH_INCLUDE and SUBARCH), and the rseq kselftests pass a
      quick build test on x86 after this.

       - Avoid a null pointer deference in machine_kexec_prepare() that the
         IMA subsystem can trigger

       - Bypass libc in part of the ptrace_v_not_enabled kselftest to avoid
         noise from child atfork handlers that libc might run

       - Include Kconfig support for UltraRISC SoCs, already referenced by
         some device drivers; and enable it in our defconfig

       - Fix the build of the rseq kselftest for RISC-V by borrowing a
         technique from the KVM and S390 kselftests that includes
         arch-specific header files from tools/arch/<arch>/include

       - Fix some memory leaks in the RISC-V vector ptrace kselftests

       - Clean up some DT bindings and hwprobe documentation"
