Subject: [Qemu-devel] [PATCH][RESEND] Don't register cpu reset handler for cpu with APIC.
Date: Thu, 18 Jun 2009 16:29:18 +0300 [thread overview]
Message-ID: <20090618132918.GF20289@redhat.com> (raw)
APIC reset handler already resets cpu, no need to reset it twice.
Also register cpu_reset handler directly to make it impossible to
add additional code to main_cpu_reset() by mistake.
