SVN rev 195779 on 2009-07-20 07:53:07Z by raj
ARM pmap fixes.
a) nocache-remap problem
When a page is remapped into a non-cacheable virtual memory region there
was no associated write-back invalidate operation performed. We remove
writeback of the original buffer size from bus_dmamem_alloc() and add
appropriate L1/L2 flush operation.
b) missing write-back invalidate operation
In pmap_kremove a page is removed so we must do a write-back
invalidate operation aligned to the page virtual address.
