ENGR00132649 SAHARA test causes ext3 file system crash
During kernel upgrade, replaced deprecated functions:
dmac_clean_range() with clean_dcache_area() and,
dmac_inv_range() with invalidate_kernel_vmap_range(),
but that results in some test case failures when file system
is on the SD card instead of NFS. Quite possibly the cache
coherency problems were not showing up during NFS testing.
Corrected this by using the proper replacements:
dmac_clean_range() replaced by dmac_map_area() and,
dmac_inv_range() replaced by dmac_unmap_area(). This fixes
the cache coherency issues and all tests pass with file system
on SD card as well mounted over NFS.
