All,
I'm trying to determine how kexec'ing works on 64 bit powerpc. When =
allocating a region for the kexec'ed kernel is it ever the same as the =
currently running kernel or do you always boot the kexec'ed kernel from =
a different memory region? I understand that a crash kernel will be in a =
different region, however I was hoping to confirm the behavior for a =
normal "kexec -e".
Thanks,
Matthew=

The kernel will be loaded at a non zero address, but it will copy itself
to zero before it starts running.
