x86/alternatives: Rename 'text_poke_queue()' to 'smp_text_poke_batch_add()'
This name is actively confusing as well, because the simple text_poke*() APIs use MM-switching based code patching, while text_poke_queue() is part of the INT3 based text_poke_int3_*() machinery that is an additional layer of functionality on top of regular text_poke*() functionality. Rename it to smp_text_poke_batch_add() to make it clear which layer it belongs to. Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Juergen Gross <jgross@suse.com> Cc: "H .
