| * sh: Fix stacktrace simplification fallout.Paul Mundt2007-05-09
| | | | | | | | | | | | | | When the stacktrace simplification changes went in the function definition on SH got skipped, fix it up so things build again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: SH7760 DMABRG support.Manuel Lauss2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMABRG is a special DMA unit within the SH7760 which does data transfers from main memory to Audio units and USB shared memory. It has 3 IRQ lines which generate 10 events, which have to be masked unmasked and acked in a single 32bit register. It works independently from the tradition SH DMAC, but blocks usage of DMAC channel 0. This patch adds 2 functions to associate callbacks with DMABRG events and initialization.

| * sh: clockevent/clocksource/hrtimers/nohz TMU support.Paul Mundt2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds basic support for clockevents and clocksources, presently only implemented for TMU-based systems (which are the majority of SH-3 and SH-4 systems). The old NO_IDLE_HZ implementation is also dropped completely, the only users of this were on TMU-based systems anyways. More work needs to be done to generalize the TMU handling, in that the current implementation is rather tied to the notion of TMU0 and TMU1 utilization. Additionally, as more SH timers switch over to this scheme, we'll be able to gut most of the remaining system timer infrastructure that existed before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Truncate MAX_ACTIVE_REGIONS for the common case.Paul Mundt2007-05-09
| | | | | | | | | | | | | | Most SH platforms aren't going to need more than a single active region, ones that need more can pad this out as necessary. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Fix PC adjustments for varying opcode length.Paul Mundt2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few different cases for figuring out how to size the instruction. We read in the instruction located at regs->pc - 4 when rewinding the opcode to figure out if there's a 32-bit opcode before the faulting instruction, with a default of a - 2 adjustment on a mismatch. In practice this works for the cases where pc - 4 is just another 16-bit opcode, or we happen to have a 32-bit and a 16-bit immediately preceeding the pc value. In the cases where we aren't rewinding, this is much less ugly.. We also don't bother fixing up the places where we're explicitly dealing with 16-bit instructions, since this might lead to confusion regarding the encoding size possibilities on other CPU variants.

| * sh: Share exception vector table for SH-3/4.Paul Mundt2007-05-08
| | | | | | | | | | | | | | | | | | | | | | The only difference between these at the moment are the FPU exceptions, and these are hidden away under CONFIG_SH_FPU (which is only set for the SH-4 case anyways..). This consolidates the two tables, and updates SH-4 to use the updated copy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Always define TRAPA_BUG_OPCODE.Paul Mundt2007-05-08
| | | | | | | | | | | | | | | | | | Previously this was only set when CONFIG_BUG=y. While we rely on that for handle_BUG() dispatch, we still want to hand the opcode off to the die chain notifier for determining the trap value. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2. Those should be able to switch easily to this version, and clean up some of the omap1-specific code. In addition to H4 support, one key improvement is supporting not just the "old" ARM debug LED API (with timer and idle LEDs, plus four that can be handy for kernel debugging), but it also supports the "new" generic LED API (most useful for usermode stuff IMO). Either or both APIs can be enabled.

The result is that the next MM fault on CPU1 updates the page table entries, but flush_tlb_page() fails due to wrong ASID. There is a related case with a threaded application is allocated a new ASID on one CPU while another of its threads is running on some different CPU. This scenario is not fixed by this commit.

It added a "mark_page_accessed(page)" at the final return path in read_cache_page_async(). But in error cases, 'page' holds the error code, and you can't mark it accessed. [ and Glauber de Oliveira Costa points out that we can use a return instead of adding more goto's ] Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
