I do git branch tmp origin/master git checkout -f tmp git merge origin/pm git merge origin/mybranch git log origin/pm^..origin/pm commit 596f2d2c8153fe24de5c3b6ad78658ce9fff7f28 Author: Kevin Hilman <[email protected]> Date: Wed Jun 17 14:42:22 2009 -0700 OMAP3: PM: default defconfig for PM kernel testing Supports 3430SDP, OMAP3EVM and 3630SDP by default. Also supports, Beagle, Overo, Zoom[23] and RX51 simply by changing System Type-->TI OMAP implementations-->Low-level debug console UART from UART1 to UART3.

Yes, I see that in source, but that function returns NULL for unknown reason.
