Luis Araneda b7005d4ef4 ARM: zynq: Use memcpy_toio instead of memcpy on smp bring-up ... This fixes a kernel panic on memcpy when FORTIFY_SOURCE is enabled. The initial smp implementation on commit aa7eb2bb4e ("arm: zynq: Add smp support") used memcpy, which worked fine until commit ee333554fe ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE") enabled overflow checks at runtime, producing a read overflow panic. The computed size of memcpy args are: - p_size (dst): 4294967295 = (size_t) -1 - q_size (src): 1 - size (len): 8 Additionally, the memory is marked as __iomem, so one of the memcpy_* functions should be used for read/write.
