ARM: smp: avoid incrementing mm_users on CPU startup We should not be incrementing mm_users when we startup a secondary CPU - doing so results in mm_users incrementing by one each time we hotplug a CPU, which will eventually wrap, and will cause problems. Other architectures such as x86 do not increment mm_users, but only mm_count, so we follow that pattern. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
