The "os-term" RTAS calls has one argument with a message address of OS termination cause. rtas_os_term() already passes it but the recently added prom_init's version of that missed it; it also does not fill args correctly. This passes the message address and initializes the number of arguments. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> --- arch/powerpc/kernel/prom_init.c | 3 +++ 1 file changed, 3 insertions(+)
