Both arch_static_branch() & arch_static_branch_jump() emit a control transfer instruction (ie. branch or jump) without disabling assembler re-ordering. As such the assembler will automatically fill their delay slots. Both functions follow their branch or jump with an explicit nop that at first appears to be there to fill the delay slot, but given that the assembler will do that the explicit nops serve no purpose & we end up with our branch or jump followed by 2 nops. Remove the redundant nops. Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: linux-mips@vger.kernel.org |
