=== Highlights ===
* Finally had the RCU lockup issue fixed - Paul McKenney found the problem and fixed it. It turns out the same bug has been seen on the OMAP, where Paul Walmsley, Becy Bruce et al had reported it. http://marc.info/?l=linux-kernel&m=134749030206016&w=2 Hunting and testing this took a lot of time.
* To progress on SPARSE_IRQ I proposed a patch to remove the warning from the GIC, and alerted Rob Herring. He didn't like that but proposed to fix the problem by fixing all descriptor allocation, which will take more time.
* Proposed a patch fixing the pinctrl IRQ desc allocations (these happen really early) and was adviced to introduce a linear IRQ domain, did this, was proposed to refactor IRQ domain core, proposed a patch for this, now following up.
* Found out how to really get rid of the ugly workarounds in the PL011 driver, only a small ST-Micro derivate-only patch was needed in the end to adjust baud rate down with ~5% on high baud rates. The rest of the patches were bogus, we weren't interfacing the TTY layer correctly. Alan Cox told me how to do it properly and lo and behold, it just works now. (All work synchronized back to ST-Ericsson's internal codebase.)
* Sent out a pinctrl patch for Nomadik I2C, but still pondering this due to regressions.
* Discussed resource handling for runtime PM and ordinary suspend/resume in the PL022 SPI driver, discussion ongoing.
* Reviewed and merged various GPIO patches.
* Reviewed and merged various pinctrl patches. Pondering PM semantics.
* Reviewed some ux500 patches coming from Lee.
=== Plans ===
* Ongoing work on sparse IRQ for Nomadik and Ux500 with the required IRQ domain refactorings.
* Follow up the rest of the above.
* Test the PL08x patches on the Ericsson Research PB11MPCore and submit platform data for using pl08x DMA on that platform.
* Look into other Ux500 stuff in need of mainlining... using an internal tracking sheet for this.
* Look into regmap. Try something out, get to know it.
=== Issues ===
* N/A
