This tag contains the following bug fixes:

Browse source 
- Fix the dma address that is passed to dma_mmap_coherent. We passed
   an address that includes an offset that is needed by our device and
   that caused dma_mmap_coherent to do an errounous mapping.
 
 - Fix the reset process in case failures happen during the reset process.
   Without this fix, if the user would have asked to perform reset after
   the previous reset failed he would get a kernel panic
 
 - WA to prevent soft lockup BUG during unmap of host memory. In case of
   tens of thousands of mappings, the unmapping can take a long time that
   exceeds the soft lockup timeout. This WA adds a small sleep every 32K
   page unmappings to prevent that.
