This is needed to support b43 on SDIO. But it also simplifies the locking by removal of the wl->irq_lock spinlock. http://bu3sch.de/patches/wireless-testing/20090816-1535/patches/002-b43-threaded-irq-handler.patch A known regression is a new race between the interrupt handler and the beacon update handler. But as long as you don't run AP mode, it won't hurt. I'm working on a solution... Please test this patch whether it creates other regressions (performance and crashes). The patch also needs the following hack to the threaded IRQ code: http://bu3sch.de/patches/wireless-testing/20090816-1535/patches/001-hack-threaded-irqs.patch -- Greetings, Michael.
