Subject[PATCH] MIPS: Loongson64: Use three arguments for slti
Date
LLVM's integrated assembler does not support 'stli <reg>, <imm>':

<instantiation>:16:12: error: invalid operand for instruction
slti $12, (0x6300 | 0x0008)
^
arch/mips/kernel/head.S:86:2: note: while in macro instantiation
kernel_entry_setup # cpu specific setup
^
<instantiation>:16:12: error: invalid operand for instruction
slti $12, (0x6300 | 0x0008)
^
arch/mips/kernel/head.S:150:2: note: while in macro instantiation
smp_slave_setup
^

To increase compatibility with LLVM's integrated assembler, use the full
form of 'stli <reg>, <reg>, <imm>', which matches the rest of
arch/mips/. This does not result in any change for GNU as.
