Asymmetric cpu capacity can not necessarily be determined accurately at the time the initial sched_domain hierarchy is built during boot. It is therefore necessary to be able to force a full rebuild of the hierarchy later triggered by the arch_topology driver. A full rebuild requires the arch-code to implement arch_update_cpu_topology() which isn't yet implemented for arm. This patch points the arm implementation to arch_topology driver to ensure that full hierarchy rebuild happens when needed. cc: Russell King <linux@armlinux.org.uk> Signed-off-by: Morten Rasmussen <morten.rasmussen@arm.com> --- arch/arm/include/asm/topology.h | 3 +++ 1 file changed, 3 insertions(+)
