[PATCH] x86: fix section mismatch from pcibios_scan_specific_bus()
This so far non-__devinit function calling a __devinit one (pci_scan_bus_on_node()) isn't correct, but since it is being exported it also cannot itself be made __devinit unconditionally. Short of being able to think of a better solution, and short of making the whole call tree (reaching into the arch-independent pa... 24 Jun 2010 11:50

[PATCH] MMC: remove regulator refcount fiddling in mmc core
Currently the mmc_regulator_set_ocr() fiddles with the regulator refcount by selectively calling regulator_[enable|disable] depending on the state of the regulator. This will confuse the reference count if case the regulator is for example shared with other MMC slots or user for other stuff than the MMC card. Pu... 24 Jun 2010 11:50

[RFC][PATCH 00/11] perf pmu interface -v2
These patches prepare the perf code for multiple pmus (no user interface yet, Lin Ming is working on that). These patches remove all weak functions and rework the struct pmu interface. The patches are boot tested on x86_64 and compile tested on: powerpc (!fsl, what config is that?), sparc and arm (sorry no SH com... 24 Jun 2010 11:50
