   2 /* Common header file that is included by all of QEMU.
   3  *
   4  * This file is supposed to be included only by .c files. No header file should
   5  * depend on qemu-common.h, as this would easily lead to circular header
   6  * dependencies.
   7  *
   8  * If a header file uses a definition from qemu-common.h, that definition
   9  * must be moved to a separate header file, and the header that uses it
  10  * must include that header.
