[ Upstream commit 10f84c2cfb5045e37d78cb5d4c8e8321e06ae18f ]

Currently, the various torture tests sometimes react to an early-boot
bug by rebooting.  This is almost always counterproductive, needlessly
consuming CPU time and bloating the console log.  This commit therefore
adds the "-no-reboot" argument to qemu so that reboot requests will
cause qemu to exit.

I don't see this commit in Linus's tree, am I just missing it somewhere?

Ah, this particular patch might not be in Linus's tree yet. It is in
Paul's tree. Feel free to ignore it for now if you want and I'll
resend it later (and likewise for the 5.10 one).

thanks,

Yeah, please just send it later, once it has landed in a -rc release
otherwise there's nothing we can do with it now, sorry.
