[POWERPC] Fix RTAS os-term usage on kernel panic
The rtas_os_term() routine was being called at the wrong time. The actual rtas call "os-term" will not ever return, and so calling it from the panic notifier is too early. Instead, call it from the machine_reset() call. This splits the rtas_os_term() routine into two: one part to capture the kernel panic message, invoked during the panic notifier, and another part that is invoked during machine_reset(). Prior to this patch, the os-term call was never being made, because panic_timeout was always non-zero. Calling os-term helps keep the hypervisor happy! We have to keep the hypervisor happy to avoid service, dump and error reporting problems. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
