Date: Mon, 20 Sep 2021 18:41:02 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Michal Suchanek <msuchanek@...e.de>, Michael Ellerman <mpe@...erman.id.au>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.4 044/260] powerpc/stacktrace: Include linux/delay.h From: Michal Suchanek <msuchanek@...e.de> [ Upstream commit a6cae77f1bc89368a4e2822afcddc45c3062d499 ] commit 7c6986ade69e ("powerpc/stacktrace: Fix spurious "stale" traces in raise_backtrace_ipi()") introduces udelay() call without including the linux/delay.h header. This may happen to work on master but the header that declares the functionshould be included nonetheless.
