We experience huge problems with cache handling on Qualcomm
systems, and it appears the dcache handling in the UFS core
is quite wrong and causes all those issues.

This serie fixes the dcache operations, and fixes a big data
write corruption due to a wrong data end address calculation.

Neil Armstrong (4):
      ufs: allocate descriptors with size aligned with DMA_MINALIGN
      ufs: fix dcache flush and invalidate range calculation
      ufs: split flush and invalidate to only invalidate when required
      ufs: use dcache helpers for scsi_cmd data and only invalidate if necessary
