From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Boyd Date: Sat, 14 Feb 2015 00:41:01 +0000 Subject: [PATCH] ARM: shmobile: Remove redundant cpu_disable implementation Message-Id: <1423874461-2405-1-git-send-email-sboyd@codeaurora.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org By default only the non-boot CPUs can be hotplugged if the smp_operations structure doesn't have the cpu_disable function pointer set. r8a7779_cpu_disable() implements the same logic, only non-boot CPUs can be hotplugged, so it's redundant to override the default behavior.
