Subject: [PATCH 25/52] ACPI: Set hotplug _OST support bit to _OSC
Date: Tue, 24 Jul 2012 23:41:21 -0400 [thread overview]
Message-ID: <c2f4191a9c4dbbb5c8bc7f2c0eb5023b97dd2a49.1343187617.git.len.brown@intel.com> (raw)
In-Reply-To: <1343187708-19532-1-git-send-email-lenb@kernel.org>
In-Reply-To: <6af1c4fc5227af65092ebc848989693562bfa3e8.1343187617.git.len.brown@intel.com>
From: Toshi Kani <toshi.kani@hp.com>
When ACPI_HOTPLUG_OST is defined, set hotplug _OST support bit
OSC_SB_HOTPLUG_OST_SUPPORT to indicate that the OS supports hotplug
_OST by calling the platform-wide ACPI Operating System Capabilities
(_OSC).
