/* Common header file that is included by all of QEMU.

|
|
* This file is supposed to be included only by .c files. No header file should
|
|
* depend on qemu-common.h, as this would easily lead to circular header
|
|
* dependencies.
|
|
*
|
|
* If a header file uses a definition from qemu-common.h, that definition
|
|
* must be moved to a separate header file, and the header that uses it
|
|
* must include that header.
