--- 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. ---
