ARM: SMP: Clean up ncores sanity checks
scu_get_core_count() never returns zero cores, so we don't need to check and correct if ncores is zero. Tegra was missing the check against NR_CPUS, leading to a potential bitfield overflow if this becomes the case. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
