| | | | | | | | | | | | | | | | This is necessary to get ftrace syscall tracing working again.. a fairly trivial and mechanical change. The one benefit is that this can also be enabled on sh64, despite not having its own ftrace port. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * | sh: clkfwk: remove bogus set_bus_parent() from SH7709.Rafael Ignacio Zurita2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up broken clock re-parenting undertaken by the SH7709 clock framework code, which is currently in conflict with the legacy CPG framework. With this change in place, the legacy CPG ancestry is used, and we manage to avoid contending on the clock_list_sem mutex, which is already held under the legacy registration path, resulting in livelock. In order for SH7709 to fully support the varying clock modes, it needs to implement a more complete clock framework. After this change it is in sync with legacy CPG mode, which ends up being the default configuration for this CPU anyways.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the cache purging is handled manually by all copy_page() callers, we can kill off copy_page()'s on writeback. This optimizes the non-aliasing case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: Use more aggressive dcache purging in kmap teardown.Paul Mundt2009-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up a number of outstanding issues observed with old mappings on the same colour hanging around. This requires some more optimal handling, but is a safe fallback until all of the corner cases have been handled. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: Fix up and optimize the kmap_coherent() interface.Paul Mundt2009-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up the kmap_coherent/kunmap_coherent() interface for recent changes both in the page fault path and the shared cache flushers, as well as adding in some optimizations. One of the key things to note here is that the TLB flush itself is deferred until the unmap, and the call in to update_mmu_cache() itself goes away, relying on the regular page fault path to handle the lazy dcache writeback if necessary.

| * | | sh: Fix up UP deadlock with SMP-aware cache ops.Paul Mundt2009-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This builds on top of the previous reversion and implements a special on_each_cpu() variant that simple disables preemption across the call while leaving the interrupt state to the function itself. There were some unintended consequences with IRQ disabling in some of these paths on UP that ran in to a deadlock scenario with IRQs being missed. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | Revert "sh: Kill off now redundant local irq disabling."Paul Mundt2009-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 64a6d72213dd810dd55bd0a503c36150af41c3c3. Unfortunately we can't use on_each_cpu() for all of the cache ops, as some of them only require preempt disabling. This seems to be the same issue that impacts the mips r4k caches, where this code was based on. This fixes up a deadlock that showed up in some IRQ context cases.

| * | | sh: Kill off kgdb's magical NMI debouncing.Paul Mundt2009-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kgdb stub has traditionally tied in to the NMI slot, and manually handled debounce. Now that we have a generic way to do this instead, all of the stub-specific debounce silliness can be killed off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: nmi_debug support.Paul Mundt2009-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for NMI debugging that was shamelessly copied from the avr32 port. A bit of special magic is needed in the interrupt exception path given that the NMI exception handler is stubbed in to the regular exception handling table despite being reported in INTEVT. So we mangle the lookup and kick off an EXPEVT-style exception dispatch from the INTEVT path for exceptions that do_IRQ() has no chance of handling. As a result, we also drop the evt2irq() conversion from the do_IRQ() path and just do it in assembly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adopts the special-cased 2-way write-through dcache flusher for N-ways and moves it in to the generic path. Assignment is done at runtime via the check for the CCR_CACHE_WT bit in the same path as the per-way writeback flushers.
