[PATCH 0/4] IPC: CRIU enhancements fixes and cleanup

This patch set simplifies message queue copy feature and clean up it's implementation. It also adds some debug and fixes an issue, when copy_msg() fails.

[PATCH 1/4] ipc: simplify free_copy() call

Passing and checking of msgflg to free_copy() is redundant. This patch sets copy to NULL on declaration instead and checks for non-NULL in free_copy(). Note: in case of copy allocation failure, error is returned immediately. So no need to check for IS_ERR() in free_copy(). Signed-off-by: Stanisla

[PATCH V4 0/2] Upstream ST-Ericsson thermal driver

From: "hongbo.zhang" V3->V4 Changes: 1. In previous patch set V3 "Fix thermal bugs and Upstream ST-Ericsson thermal driver", there were 5 patches in total, since the first 3 for fixing thermal layer bugs have been accepted by the maintainer, I'd like to send out the updated last 2 only this time

[PATCH V4 1/2] Thermal: Add ST-Ericsson DB8500 thermal driver.

From: "hongbo.zhang" This driver is based on the thermal management framework in thermal_sys.c. A thermal zone device is created with the trip points to which cooling devices can be bound, the current cooling device is cpufreq, e.g. CPU frequency is clipped down to cool the CPU, and other cooling

[PATCH V4 2/2] Thermal: Add ST-Ericsson DB8500 thermal properties and platform data.
