If so, then explain that here. better? --- Subject: [PATCH] x86, boot: move verify_cpu.S and no_longmode down We need to move some code with 32bit section in following patch: x86, boot: Move lldt/ltr out of 64bit code section but that will push startup_64 down from 0x200. According to hpa, we can not change startup_64 to other offset and that become ABI now. We could move function verify_cpu and no_longmode down, because verify_cpu is used via function call and no_longmode will not return. --- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
