  Hi,

The current dvb code has some portability problems, see the ppc64
build log below.

Some of the failures look harmless, just a missing include
(vmalloc_to_page) or due to recent irq API changes (request_irq
warning).

The virt_to_bus() is a big no-no, this isn't portable, the drivers
should use the dma mapping interface (Documentation/DMA-mapping.txt)
instead.
