[PATCH] powerpc/irq: Quieten irq mapping printks

2011-07-07 Thread Anton Blanchard
HFI creates interrupts each time a window is setup. This results in a lot of messages in the kernel log buffer: irq: irq 199007 on host null mapped to virtual irq 351 This box has over 3500 of them, causing more important kernel messages to be overwritten. We can get at this information via

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

Instead of using ill-defined numbers (0, 1, and 2) for the monitor port, allow the user to specify the port by name ("dvi", "lvds", or "dlvds"). This works on the kernel command line, the module command-line, and the sysfs "monitor" device. Note that changing the monitor port does not currently w
