2007-03-05sh: Revert lazy dcache writeback changes.Paul Mundt
These ended up causing too many problems on older parts, revert for now.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Local TLB flushing variants for SMP prep.Paul Mundt
Rename the existing flush routines to local_ variants for use by the IPI-backed global flush routines on SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Lazy dcache writeback optimizations.Paul Mundt
This converts the lazy dcache handling to the model described in Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a bonus, this slightly cuts down on the cache flushing frequency. With that and the PTEA handling out of the way, the update_mmu_cache() implementations can be consolidated, and we no longer have to worry about which configuration the cache is in for the SH7705 case. And finally, explicitly disable the lazy writeback on SMP (SH-4A). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
