* [PATCH] Optimize D-cache alias handling on forkRalf Baechle2006-12-131-0/+3
| | | | | | | | | | | Virtually index, physically tagged cache architectures can get away without cache flushing when forking. This patch adds a new cache flushing function flush_cache_dup_mm(struct mm_struct *) which for the moment I've implemented to do the same thing on all architectures except on MIPS where it's a no-op.

* sh: Kill off more dead headers.Paul Mundt2006-10-031-25/+0
| | | | | | Some old rtc and io headers were left hanging around, kill them off.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Calculate shm alignment at runtime.Paul Mundt2006-09-271-8/+0
| | | | | | | Set the SHM alignment at runtime, based off of probed cache desc. Optimize get_unmapped_area() to only colour align shared mappings. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add support for SH7706/SH7710/SH7343 CPUs.Paul Mundt2006-09-274-6/+22
| | | | | | | This adds support for the aforementioned CPU subtypes, and cleans up some build issues encountered as a result. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: APM/PM support.Andriy Skulysh2006-09-271-0/+4
| | | | | | | | | This adds some simple PM stubs and the basic APM interfaces, primarily for use by hp6xx, where the existing userland expects it. Signed-off-by: Andriy Skulysh <askulysh@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fixup SHMLBA definition for SH7705.Paul Mundt2006-09-272-43/+21
| | | | | | | We need this set to something sensible anywhere were we have an aliasing dcache.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: page table alloc cleanups and page fault optimizations.Paul Mundt2006-09-271-7/+1
| | | | | | | | | | | Cleanup of page table allocators, using generic folded PMD and PUD helpers. TLB flushing operations are moved to a more sensible spot. The page fault handler is also optimized slightly, we no longer waste cycles on IRQ disabling for flushing of the page from the ITLB, since we're already under CLI protection by the initial exception handler.

* sh: Fixup TMU_TOCR definition for SH7300.Paul Mundt2006-09-271-3/+4
| | | | | | SH7300 has a different TMU_TOCR, make the TMU code work again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* [PATCH] sh: Move TRA/EXPEVT/INTEVT definitions for reusePaul Mundt2006-02-011-0/+10
| | | | | | | | | Currently entry.S is home to these definitions, so we move them somewhere more sensible. IPR IRQ handling depends on being to read from INTEVT.

* [PATCH] sh: DMA updatesPaul Mundt2006-01-161-1/+30
| | | | | | | | | | | | | This extends the current SH DMA API somewhat to support a proper virtual channel abstraction, and also works to represent this through the driver model by giving each DMAC its own platform device. There's also a few other minor changes to support a few new CPU subtypes, and make TEI generation for the SH DMAC configurable.

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!
