-Subject: [RFC PATCH] ARM: zynq: Use memcpy_toio instead of memcpy on smp bring-up
-
-This fixes a kernel panic (read overflow) on memcpy when
-FORTIFY_SOURCE is enabled.
-
-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
-
