      tooling/headers: Synchronize updated s390 and x86 UAPI headers · 34c9ca37
      Ingo Molnar authored
      There were two trivial updates to these upstream UAPI headers:
      Synchronize them with their tooling copies.
      (The x86 opcode map includes a new instruction pattern now.)

      objtool: Fix 64-bit build on 32-bit host · 14c47b54
      Mikulas Patocka authored
      The new ORC unwinder breaks the build of a 64-bit kernel on a 32-bit
      host.  Building the kernel on a i386 or x32 host fails with:
        orc_dump.c: In function 'orc_dump':
        orc_dump.c:105:26: error: passing argument 2 of 'elf_getshdrnum' from incompatible pointer type [-Werror=incompatible-pointer-types]
          if (elf_getshdrnum(elf, &nr_sections)) {
        In file included from /usr/local/include/gelf.h:32:0,
                         from elf.h:22,
                         from warn.h:26,
                         from orc_dump.c:20:
        /usr/local/include/libelf.h:304:12: note: expected 'size_t * {aka unsigned int *}' but argument is of type 'long unsigned int *'
         extern int elf_getshdrnum (Elf *__elf, size_t *__dst);
        orc_dump.c:190:17: error: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'Elf64_Sxword {aka long long int}' [-Werror=format=]
            printf("%s+%lx:", name, rela.r_addend);
                       ~~^          ~~~~~~~~~~~~~
      Fix the build failure.
      Another problem is that if the user specifies HOSTCC or HOSTLD
      variables, they are ignored in the objtool makefile.  Change the
      Makefile to respect these variables.
