Subject: [PATCH v2 19/28] powerpc/pseries/hibernation: remove pseries_suspend_cpu()
Date: Mon, 7 Dec 2020 15:51:51 -0600 [thread overview]
Message-ID: <20201207215200.1785968-20-nathanl@linux.ibm.com> (raw)
In-Reply-To: <20201207215200.1785968-1-nathanl@linux.ibm.com>
Since commit 48f6e7f6d948 ("powerpc/pseries: remove cede offline state
for CPUs"), ppc_md.suspend_disable_cpu() is no longer used and all
CPUs (save one) are placed into true offline state as opposed to
H_JOIN. So pseries_suspend_cpu() is effectively unused; remove it.
