-From: Prasad J Pandit <address@hidden>
-
-When IDE AHCI emulation uses Frame Information Structures(FIS)
-engine for data transfer, the mapped FIS buffer address is stored
-in a static 'bounce.buffer'. When a request is made to map another
-memory region, address_space_map() returns NULL because
-'bounce.buffer' is in_use. It leads to a null pointer dereference
-error while doing 'dma_memory_unmap'. Add a check to avoid it.
