From 622a9edd919de98ef59571ae6c40c7458244e3f2 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 16 Oct 2007 23:29:42 -0700 Subject: Remove dma_cache_(wback|inv|wback_inv) functions 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. Signed-off-by: Ralf Baechle Acked-by: Paul Mundt Acked-by: Paul Mackerras Acked-by: David S.
