When we cannot emulate an atomic operation within a parallel context, this exception allows us to stop the world and try again in a serial context. Backports commit fdbc2b5722f6092e47181a947c90fd4bdcc1c121 from qemu Also backports parts of commit 02d57ea115b7669f588371c86484a2e8ebc369be

/* 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.
