Default crash-5.0: Segmentation fault with x86_64_get_active_set

Hello,



I get segementation fault from our 64-bit kernel crash

This crash is caused by "echo c > /proc/sys-trigger".

The reason seems to be that the x86_64_cpu_pda_init is

not called at least gdb do not break there.



Here is a little patch that fixes it. Everyting seems
to

work correctly. I'll provide more info if needed.
