* staging: octeon-usb: prevent memory corruptionAaro Koskinen2014-03-201-0/+108
| | | | | | | | | | | | | | | | | | octeon-hcd will crash the kernel when SLOB is used. This usually happens after the 18-byte control transfer when a device descriptor is read. The DMA engine is always transfering full 32-bit words and if the transfer is shorter, some random garbage appears after the buffer. The problem is not visible with SLUB since it rounds up the allocations to word boundary, and the extra bytes will go undetected. Fix by providing quirk functions for DMA map/unmap that allocate a bigger temporary buffer when necessary. Tested by booting EdgeRouter Lite to USB stick root file system with SLAB, SLOB and SLUB kernels.

* usb: hcd: move controller wakeup setting initialization to individual driverPeter Chen2013-12-091-0/+1
| | | | | | | | | | | | | | | Individual controller driver has different requirement for wakeup setting, so move it from core to itself. In order to align with current etting the default wakeup setting is enabled (except for chipidea host).
