It is actually two patches that cause the breakage. The other is:
commit e55aeb6ba4e8cc3549bff1e75ea1d029324bce21 of/irq: Mark interrupt controllers as populated before initialisation
I needed to revert both of these in order to get MMC working on our 71xx and 78xx boards. For our MMC, I got error messages from the MMC core of "Invalid POWER GPIO" until I applied the second patch. I will have a fix worthy of upstreaming today which will be posted today.
