Date: Wed, 15 Apr 2020 07:41:25 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Alexey Kardashevskiy <aik@...abs.ru>, Michael Ellerman <mpe@...erman.id.au>, Sasha Levin <sashal@...nel.org>, linuxppc-dev@...ts.ozlabs.org Subject: [PATCH AUTOSEL 5.5 045/106] powerpc/prom_init: Pass the "os-term" message to hypervisor From: Alexey Kardashevskiy <aik@...abs.ru> [ Upstream commit 74bb84e5117146fa73eb9d01305975c53022b3c3 ] 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.
