The patch titled
iomap: fix 64 bits resources on 32 bits
has been removed from the -mm tree. Its filename was
iomap-fix-64-bits-resources-on-32-bits.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: iomap: fix 64 bits resources on 32 bits
From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>
Almost all implementations of pci_iomap() in the kernel, including the generic
lib/iomap.c one, copies the content of a struct resource into unsigned long's
which will break on 32 bits platforms with 64 bits resources.
This fixes all definitions of pci_iomap() to use resource_size_t. I also
"fixed" the 64bits arch for consistency.
