[PATCH 0 of 2] Much smaller MMIO copy patches
From: Bryan O'Sullivan
Date: Wed Jan 11 2006 - 19:29:21 EST
These MMIO copy patches are lean, mean, and apparently clean.
These define the generic __raw_memcpy_toio32 as a weak symbol, which
arches are free to override. We provide a specialised implementation
for x86_64.
We also introduce include/linux/io.h, which is tiny now, but a candidate
for later cleanups of all the per-arch asm-*/io.h files.
These patches should apply cleanly against current -git, and have been
tested on i386 and x86_64. The symbol shows up in the built vmlinux,
as one might hope.
The patch series is as follows:
raw_memcpy_io.patch
Introduce the generic MMIO 32-bit copy routine.
x86_64-raw_memcpy_io.patch
Add a faster __raw_memcpy_io32 routine to x86_64.
