      When scripts/get_maintainer.pl reports something like
      
          John Doe <jdoe@xxxxxxxxxxx> (maintainer:Overall)
      
      the user is left to wonder *which* of our three "Overall" sections
      applies: the one under "Guest CPU cores (TCG)", or the one under
      "Guest CPU Cores (KVM)", or the one under "Usermode emulation".
      
      Rename sections under
      
      * "Guest CPU cores (TCG)" from "FOO" to "FOO TCG CPUs"
      
      * "Guest CPU Cores (KVM)" from "FOO" to "FOO KVM CPUs"
      
      * "Guest CPU Cores (Xen)" from "FOO" to "FOO Xen CPUs"

        support"

      Clean up a few header guard symbols
      
      Commit 58ea30f5145 "Clean up header guards that don't match their file
      name" messed up contrib/elf2dmp/qemu_elf.h and
      tests/migration/migration-test.h.
      
      It missed target/cris/opcode-cris.h and
      tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h
      due to the scripts/clean-header-guards.pl bug fixed in the previous
      commit.
      
      Commit a8b991b52dc "Clean up ill-advised or unusual header guards"
      missed include/hw/xen/io/ring.h for the same reason.
      
      Commit 3979fca4b69 "disas: Rename include/disas/bfd.h back to
      include/disas/dis-asm.h" neglected to update the guard symbol for the
      rename.
      
      Commit a331c6d7741 "semihosting: implement a semihosting console"
      created include/hw/semihosting/console.h with an ill-advised guard
      symbol.
      
      Clean them up.

      scripts/clean-header-guards: Fix handling of trailing comments
      
      clean-header-guards.pl fails to recognize a header guard #endif when
      it's followed by a // comment, or multiple comments.  Fix that.

  commit 0553d895f98d6ffa7354dee324ff7a65fca3367f
  Author: Markus Armbruster <armbru@xxxxxxxxxx>
  Date:   Tue Jun 4 20:16:15 2019 +0200
  
      Normalize position of header guard
      
      This is the common header guard idiom:
      
          /*
           * File comment
           */
      
          #ifndef GUARD_SYMBOL_H
          #define GUARD_SYMBOL_H
      
          ... actual contents ...
      
          #endif
      
      A few of our headers have some #include before the guard.
      target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard.
      A few more have the #define elsewhere.
      
      Change them to match the common idiom.  For spr_def_64.h, that means
      dropping #ifndef __DOXYGEN__.  While there, rename guard symbols to
      make scripts/clean-header-guards.pl happy.

      qemu-common: Move tcg_enabled() etc. to sysemu/tcg.h
      
      Other accelerators have their own headers: sysemu/hax.h, sysemu/hvf.h,
      sysemu/kvm.h, sysemu/whpx.h.  Only tcg_enabled() & friends sit in
      qemu-common.h.  This necessitates inclusion of qemu-common.h into
      headers, which is against the rules spelled out in qemu-common.h's
      file comment.
      
      Move tcg_enabled() & friends into their own header sysemu/tcg.h, and
      adjust #include directives.

      the user is left to wonder *which* of our three "Overall" sections

      Clean up a few header guard symbols
      
      Commit 58ea30f5145 "Clean up header guards that don't match their file
      name" messed up contrib/elf2dmp/qemu_elf.h and
      tests/migration/migration-test.h.
      
      It missed target/cris/opcode-cris.h and
      tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h
      due to the scripts/clean-header-guards.pl bug fixed in the previous
      commit.
      
      Commit a8b991b52dc "Clean up ill-advised or unusual header guards"
      missed include/hw/xen/io/ring.h for the same reason.
      
      Commit 3979fca4b69 "disas: Rename include/disas/bfd.h back to
      include/disas/dis-asm.h" neglected to update the guard symbol for the
      rename.
      
      Commit a331c6d7741 "semihosting: implement a semihosting console"
      created include/hw/semihosting/console.h with an ill-advised guard
      symbol.
      
      Clean them up.

      scripts/clean-header-guards: Fix handling of trailing comments
      
      clean-header-guards.pl fails to recognize a header guard #endif when

  commit 0553d895f98d6ffa7354dee324ff7a65fca3367f
  Author: Markus Armbruster <armbru@xxxxxxxxxx>
  Date:   Tue Jun 4 20:16:15 2019 +0200
  
      Normalize position of header guard
      
      This is the common header guard idiom:
      
          /*
           * File comment
           */
      
          #ifndef GUARD_SYMBOL_H
          #define GUARD_SYMBOL_H
      
          ... actual contents ...
      
          #endif
      
      A few of our headers have some #include before the guard.
      target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard.
      A few more have the #define elsewhere.
      
      Change them to match the common idiom.  For spr_def_64.h, that means
      dropping #ifndef __DOXYGEN__.  While there, rename guard symbols to
      make scripts/clean-header-guards.pl happy.

      qemu-common: Move tcg_enabled() etc. to sysemu/tcg.h
      
      Other accelerators have their own headers: sysemu/hax.h, sysemu/hvf.h,
      sysemu/kvm.h, sysemu/whpx.h.  Only tcg_enabled() & friends sit in
      qemu-common.h.  This necessitates inclusion of qemu-common.h into
      headers, which is against the rules spelled out in qemu-common.h's
      file comment.
      
      Move tcg_enabled() & friends into their own header sysemu/tcg.h, and
      adjust #include directives.
