[PATCH 1/3] driver core: Add ability for arch code to setup pdev_archdata
On some architectures we need to setup pdev_archdata before we add the device. Waiting til a bus_notifier is too late since we might need the pdev_archdata in the bus notifier. One example is setting up of dma_mask pointers such that it can be used in a bus_notifier. We add ARCH_HAS_PDEV_ARCHDATA_SETUP and a du... 5 Aug 2010 12:26

[PATCH 1/2] lockdep: Remove __debug_show_held_locks
There is no longer any functional difference between __debug_show_held_locks() and debug_show_held_locks(), so remove the former.

[PATCH 0/3] driver core: Add ability for arch code to setup pdev_archdata
On PPC we need to set the dma_mask pointer for platform_devices to point to the pdev_archdata. We can't wait for a bus_notifier as we need the dma_mask setup before the platform_device_add happens so that the bus_notifiers can check the dma_mask to determine if we need things like the SWIOTLB dma_ops. The patch ... 5 Aug 2010 12:26

[PATCH 3/3] powerpc: Dont require a dma_ops struct to set dma mask
The only reason to require a dma_ops struct is to see if it has implemented set_dma_mask. If not we can fall back to setting the mask directly. This resolves an issue with how to sequence the setting of a DMA mask for platform devices. Before we had an issue in that we have no way of setting the DMA mask befor... 5 Aug 2010 12:26

[PATCH] perf,x86: P4 PMU -- update nmi irq statistics and unmask lvt entry properly
In case if last active performance counter is not overflowed at moment of NMI being triggered by another counter, the irq statistics may miss an update stage. As a more serious consequence -- apic quirk may not be triggered so apic lvt entry stay masked. Tested-by: Lin Ming <ming.m.lin(a)intel.com> Signed-off-by: ... 5 Aug 2010 11:20

This is a patch to the adl_pci9111.c file that fixes up most over 80 characters warnings found by the checkpatch.pl tool.
