Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc updates from David Miller:
"The PowerPC folks have a really nice scalable IOMMU pool allocator
that we wanted to make use of for sparc. So here we have a series
that abstracts out their code into a common layer that anyone can make
use of.
Sparc is converted, and the PowerPC folks have reviewed and ACK'd this
series and plan to convert PowerPC over as well"
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
iommu-common: Fix PARISC compile-time warnings
sparc: Make LDC use common iommu poll management functions
sparc: Make sparc64 use scalable lib/iommu-common.c functions
sparc: Break up monolithic iommu table/lock into finer graularity pools and lock
