Subject: s390x: Don't do a normal reset on the initial cpu
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ec9227339fce99412830d44a37eb0bd2fadd5f75;p=qemu.git

s390x: Don't do a normal reset on the initial cpu

The initiating cpu needs to be reset with an initial reset. While
doing a normal reset followed by a initial reset is not wrong per se,
the Ultravisor will only allow the correct reset to be performed.
