Subject: [PATCH 3.18 19/50] ARM: 8510/1: rework ARM_CPU_SUSPEND dependencies
Date: Mon, 1 Apr 2019 19:03:02 +0200 [thread overview]
Message-ID: <20190401170043.576990744@linuxfoundation.org> (raw)
In-Reply-To: <20190401170041.257273804@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 1b9bdf5c1661873a10e193b8cbb803a87fe5c4a1 ]
The code enabled by the ARM_CPU_SUSPEND config option is used by
kernel subsystems for purposes that go beyond system suspend so its
config entry should be augmented to take more default options into
account and avoid forcing its selection to prevent dependencies
override.
To achieve this goal, this patch reworks the ARM_CPU_SUSPEND config
entry and updates its default config value (by adding the BL_SWITCHER
option to it) and its dependencies (ARCH_SUSPEND_POSSIBLE), so that the
symbol is still selected by default by the subsystems requiring it and
at the same time enforcing the dependencies correctly.
