Subject: [RFC PATCH v2 8/9] sparc/sun4m: Use one cpu_reset() function for main and secondary CPUs
Date: Wed, 22 Jul 2020 00:50:15 -0300	[thread overview]
Message-ID: <20200722035016.469075-9-bauerman@linux.ibm.com> (raw)
In-Reply-To: <20200722035016.469075-1-bauerman@linux.ibm.com>

If we rely on cpu_common_reset() setting CPUState::halted according to the
start-powered-off property, both reset functions become equivalent and we
can use only one.
