ENGR00290463 revert exact pages allocator to fix system reboot issue
System reboot occur during 1080p recording if exit MovieStudio after play a mixed clip with single HDMI, Vivante's intial feedback is alloc_pages_exact/free_pages_exact APIs are not stable in some kernel, In other side, need check if some memory size miscalculated is hided by this optimization. Temporarily this optimization shall be reverted to fix the critical issue. Signed-off-by: Xianzhong <b07117@freescale.com> Acked-by: Jason Liu
