[PATCH 2.6.24-rt1] SMC91x: Use special_lock when CONFIG_PREEMPT_[HARD|SOFT]IRQS

The smc_special_locks should also be used when either softIRQs or hard IRQs are preempted which may lead to the same problems as under SMP. Signed-off-by: Kevin Hilman [EMAIL PROTECTED] --- drivers/net/smc91x.c |3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/drivers

Steven Rostedt [EMAIL PROTECTED] writes: I'm about to gut the RT latency tracer with the version I'm pushing upstream. This will be some of the changes: Might I request that you follow the mainline stabilization model and wait until the 2.6.25-rcX-rtY series to make a significant change like

Generic IRQs: proper edge/level via irq_chip-set_type hook

I'm trying to cleanup/remove the use of handle_simple_irq in the OMAP GPIO IRQ handling. Currently, the OMAP GPIO demux handler uses handle_simple_irq for all the GPIOs whether they are edge or level. The result is duplicated logic with handle_[edge|level]_irq as well as things not working

[PATCH] ARM: OMAP: Fix GPIO IRQ unmask

GPIO IRQ unmask doesn't actually do anything useful. The problem is hidden by a separate explicit mass unmask at the end of the chained bank handler. Signed-off-by: Kevin Hilman [EMAIL PROTECTED] --- arch/arm/plat-omap/gpio.c |3 +-- 1 files changed, 1 insertions(+), 2 deletions(-) diff

[PATCH] ARM: OMAP: Clear level-triggered GPIO interrupts in unmask hook

The clearing was moved to the unmask hook because it is known to run after the interrupt handler has actually run. Before this patch, if interrupts were threaded, the clearing/unmasking of level triggered interrupts could be done before the threaded handler actually ran. Signed-off-by: Kevin
