[ Upstream commit fd7710cb491f900eb63d2ce5aac0e682003e84e9 ]
Commit 3c1d3f097972 ("MIPS: futex: Emit Loongson3 sync workarounds within asm") inadvertently removed the newlines following __WEAK_LLSC_MB, which causes build failures for configurations in which __WEAK_LLSC_MB expands to a sync instruction:
{standard input}: Assembler messages: {standard input}:9346: Error: symbol `sync3' is already defined {standard input}:9380: Error: symbol `sync3' is already defined ...
Fix this by restoring the newlines to separate the sync instruction from anything following it (such as the 3: label), preventing inadvertent concatenation.
