You are right, it should say "at" here instead of "ax". The code uses
the MIPS "at" register. AX is a BPF register, so this is a typo in my
commit message.

Thanks,

This patch implements a workaround for the Loongson-2F nop in generated,
code, if the existing option CONFIG_CPU_NOP_WORKAROUND is set. Before,
the binutils option -mfix-loongson2f-nop was enabled, but no workaround
was done when emitting MIPS code. Now, the nop pseudo instruction is
emitted as "or ax,ax,zero" instead of the default "sll zero,zero,0". This

 Confusing typo here, s/ax/at/.
