Subject: [ 23/47] [PATCH] Revert "usb: Fix build error due to dma_mask is not at
 pdev_archdata at ARM"

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

This reverts commit d39514c14bd941232976b68e2750dc725b90e724 which is
e90fc3cb087ce5c5f81e814358222cd6d197b5db upstream as it causes oopses on
some ppc systems.
