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.
arch/mips/kernel/relocate_kernel.S: Assembler messages:
arch/mips/kernel/relocate_kernel.S:162: Error: operation combines symbols in different segments
