[PATCH 36/41] x86/alternatives: Remove the mixed-patching restriction on text_poke_int3()

[Ingo Molnar]

At this point text_poke_int3(addr, opcode, len, emulate) is equivalent to:

	text_poke_int3_queue(addr, opcode, len, emulate);
	text_poke_int3_finish();

So remove the restriction on mixing single-instruction patching
with multi-instruction patching.
