Subject: [net-next-2.6 PATCH 3/9] vxge: Removed accessing non-supported
 registers.

 - Removed accessing GENDMA_INT register
 - This allowed the firmware to perform a generic DMA write to host memory.
   This feature is not supported by the ASIC, this patch removes access to
   GENDMA_INT register.
