[Crash-utility] crash-5.0: Segmentation fault with x86_64_get_active_set

[ville.mattila at stonesoft.com]

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.
