Being so late in 3.2-rc, it would be preferred to apply&push David's patch for 3.2, and then get Rob's into libata-dev#upstream (linux-next). That OK?

It depends upon CONFIG_OF_IRQ which not all CONFIG_OF platforms support, in particular sparc does not support CONFIG_OF_PLATFORM because it precomputes all IRQs at boot time when it scans the device tree so all of the CONFIG_OF_IRQ infrastructure to probe and resolve IRQs at driver probe time is wrong and completely unnecessary. Add the proper dependencies so that pata_of_platform.c doesn't get built on sparc. CONFIG_OF_IRQ was severely misdesigned, it should just NOP out on platforms where the architecture has the final IRQ values already like sparc does. But that's not how it was implemented at all, and now we're starting to have all of these drivers get hard dependencies on this mechanism and it's datastructures, and the resulting sparc build failures from time to time. Jeff, please push something like the following to Linus so that sparc's allmodconfig builds again. Thanks. -------------------- pata_of_platform: Add missing CONFIG_OF_IRQ dependency.
