Subject: Remove dma_cache_(wback|inv|wback_inv) functions
From: Ralf Baechle <[EMAIL PROTECTED]>
dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes. Originally it was basically the raw
MIPS low level cache API exported to the entire world. The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync. So
remove it rsp. turn the surviving bits back into an arch private API, as
discussed on linux-arch.
