| H A D | busdma_machdep-v4.c | diff 195779 Mon Jul 20 06:01:45 MDT 2009 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.
