+Subject: MIPS: Fix compiling failure of relocate_kernel.S
+
+The following errors is fixed with the help of <asm/asm_nosec.h>. for
+this file need to put different symbols in the same section, the
+original LEAF, NESTED and EXPORT (without explicit section indication)
+must be used, <asm/asm_nosec.h> does it.
