| |
Hi guys,
The arch/i386/kernel/smpboot.c:do_boot_cpu() uses setup_trampoline() to copy the trampoline.S code for each cpu. Why not point all of them to the same copy? So I looked in trampoline.S and discovered the answer to this question - because each instance writes some magic number a5a5a5a5 to its code. Ok, so then the answer becomes - why does it do that?
Any ideas?
Regards, Tigran
