sh: Fixup last users of irq_chip->typename

2009-11-18T01:50:22+00:00

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

sh: Don't enable interrupts in the page fault path

2009-09-28T06:11:45+00:00

There's already code in do_page_fault() to conditionally enable
interrupts, so we don't need to unconditonally enable them before
calling it. This fixes a lockdep warning where we called
trace_hardirqs_off() but with irqs still enabled.

sh: multi-evt support for SH-X3 proto CPU.

2009-09-14T08:29:35+00:00

This adds support for multiple vectors per unique IRQ masking source on
the SH-X3 proto CPU.

sh: clkfwk: remove bogus set_bus_parent() from SH7709.

2009-09-14T05:09:00+00:00

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.

sh: Kill off kgdb's magical NMI debouncing.

2009-09-01T08:45:35+00:00

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.

sh: nmi_debug support.

2009-09-01T08:38:32+00:00

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.
