[ARM SMP] Ensure secondary CPUs have a clean TLB
Since ARMv6 CPUs will not flush the TLB on context switches, it is possible that we may end up with some global TLB entries remaining present, eventually upsetting userspace. Explicitly flush the entire TLB on secondary CPUs as they startup, after we have switched to the init_mm page tables. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
