The patch titled
Subject: platform-x86: intel_mid_thermal: convert to use Intel MSIC API
has been removed from the -mm tree. Its filename was
platform-x86-intel_mid_thermal-convert-to-use-intel-msic-api.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: platform-x86: intel_mid_thermal: convert to use Intel MSIC API
Intel MSIC MFD driver provides common register access interface to the
devices in the MSIC die so we use that instead of SCU IPC.
