Tested and used for several years by GNS3, it doesn't break the build.
|
|
|
|
I could not access http://git.qemu.org/qemu.git/plain/CODING_STYLE and
|
|
http://git.qemu.org/qemu.git/plain/HACKING (404) so these patches may
|
|
not be 100% conform. The script didn't report any error though.

[agraf] I combined the upstream submitted mail header with the 0.14 Uli
|
|
version of the patch. If this isn't upstream by 1.1, remove in
|
|
the next round!
