From e1531b4218a7ccfc1b2234b87105201e5ebe1bbf Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Mon, 7 Nov 2005 00:57:54 -0800 Subject: [PATCH] ia64: re-implement dma_get_cache_alignment to avoid EXPORT_SYMBOL The current ia64 implementation of dma_get_cache_alignment does not work for modules because it relies on a symbol which is not exported. Direct access to a global is a little ugly anyway, so this patch re-implements dma_get_cache_alignment in a manner similar to what is currently used for x86_64. Signed-off-by: John W.

This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call. For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.
