From 36dbd9548e92268127b0c31b0e121e63e9207108 Mon Sep 17 00:00:00 2001 From: Michael Buesch Date: Fri, 4 Sep 2009 22:51:29 +0200 Subject: b43: Use a threaded IRQ handler Use a threaded IRQ handler to allow locking the mutex and sleeping while executing an interrupt. This removes usage of the irq_lock spinlock, but introduces a new hardirq_lock, which is _only_ used for the PCI/SSB lowlevel hard-irq handler. Sleeping busses (SDIO) will use mutex instead.
