[PATCH 0 of 3] 32-bit MMIO copy routines, reworked
From: Bryan O'Sullivan
Date: Tue Jan 10 2006 - 14:54:30 EST
After some more review comments from Roland, Andrew and Chris Hellwig,
here is a reworked set of 32-bit MMIO copy patches.
These use CONFIG_RAW_MEMCPY_IO to determine whether an arch should use
the generic __raw_memcpy_toio32 routine or its own specialised version.
We provide a specialised implementation for x86_64.
These patches should apply cleanly against current -git, and have been
tested on i386 and x86_64.
The patch series is as follows:
raw_memcpy_io.patch
Introduce the generic MMIO 32-bit copy routine.
x86_64-memcpy32.patch
Add memcpy32 routine to x86_64.
arch-specific-raw_memcpy_io.patch
Get each arch to use generic memcpy_io code, except x86_64, which
uses memcpy32.
