Check whether the TLB operations need broadcasting on SMP systems
ARMv7 SMP hardware can handle the TLB maintenance operations broadcasting in hardware so that the software can avoid the costly IPIs. This patch adds the necessary checks (the MMFR3 CPUID register) to avoid the broadcasting if already supported by the hardware. (this patch is based on the work done by Tony Thompson @ ARM) Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
