[1/1] ARM: rockchip: Use memcpy_toio instead of memcpy on smp bring-up commit: 423e85e97aaf69e5198bbec6811e3825c8b5019a Best regards,

This fixes a potential kernel panic on memcpy when FORTIFY_SOURCE is enabled. Because memory is iomem use appropriate function for accessing it. Signed-off-by: Ivan T. Ivanov <iivanov@suse.de> --- arch/arm/mach-rockchip/platsmp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
