+Subject: drm/i915: Configure the TV sense state correctly on GM45 to make TV detection reliable
+
+From: Zhao Yakui <yakui.zhao@intel.com>
+
+commit fb8b5a39b6310379d7b54c0c7113703a8eaf4a57 upstream.
+
+The TV detection logic is not reliable on the Cantiga platform.
+Sometimes the TV will be misdetected as the following two cases:
+- TV is misdetected on some laptops. e.g. There is no TV connector
+port or no TV is attached. But the TV is shown as connected.
+- TV connector type is misdetected. e.g. the component TV is
+attached, but the TV is shown as S-video type.
+
+According to the hardware requirement, the TV sense state bits of TV DAC
+register should be cleared to zero on Cantiga platfrom.

+Subject: powerpc: Fix handling of strncmp with zero len
+
+From: Jeff Mahoney <jeffm@suse.com>
+
+commit 637a99022fb119b90fb281715d13172f0394fc12 upstream.
+
+Commit 0119536c, which added the assembly version of strncmp to
+powerpc, mentions that it adds two instructions to the version from
+boot/string.S to allow it to handle len=0. Unfortunately, it doesn't
+always return 0 when that is the case. The length is passed in r5, but
+the return value is passed back in r3. In certain cases, this will
+happen to work. Otherwise it will pass back the address of the first
+string as the return value.
+
+This patch lifts the len <= 0 handling code from memcpy to handle that
+case.

+commit f8b67691828321f5c85bb853283aa101ae673130 upstream.

+This moves query_cpu_stopped() out of the hotplug cpu code and into

+smp_query_cpu_stopped().
+
+It also cleans up the return values by adding some #defines

+Subject: powerpc/pseries: Only call start-cpu when a CPU is stopped
+
+From: Michael Neuling <mikey@neuling.org>
+
+commit aef40e87d866355ffd279ab21021de733242d0d5 upstream.
+
+Currently we always call start-cpu irrespective of if the CPU is
+stopped or not. Unfortunatley on POWER7, firmware seems to not like
+start-cpu being called when a cpu already been started. This was not
+the case on POWER6 and earlier.
+
+This patch checks to see if the CPU is stopped or not via an
+query-cpu-stopped-state call, and only calls start-cpu on CPUs which
+are stopped.
+
+This fixes a bug with kexec on POWER7 on PHYP where only the primary
+thread would make it to the second kernel.
