From: Ralf Baechle <ralf@xxxxxxxxxxxxxx> Commit a4d7f14bd8d3316f847c3e0f7020dad95a8a648a upstream. When expanding the la or dla pseudo-instruction in a delay slot the GNU assembler will complain should the pseudo-instruction expand to multiple actual instructions, since only the first of them will be in the delay slot leading to the pseudo-instruction being only partially executed if the branch is taken. Use of PTR_LA in the dec int-handler.S leads to such warnings: arch/mips/dec/int-handler.S: Assembler messages: arch/mips/dec/int-handler.S:149: Warning: macro instruction expanded into multiple instructions in a branch delay slot arch/mips/dec/int-handler.S:198: Warning: macro instruction expanded into multiple instructions in a branch delay slot Avoid this by open coding the PTR_LA macros.
