From fd0504c3217d6d1bc8f33f53fb536299cae8feda Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 20 Jun 2006 01:20:00 -0700 Subject: [SPARC64]: Send all device interrupts via one PIL. This is the first in a series of cleanups that will hopefully allow a seamless attempt at using the generic IRQ handling infrastructure in the Linux kernel. Define PIL_DEVICE_IRQ and vector all device interrupts through there. Get rid of the ugly pil0_dummy_{bucket,desc}, instead vector the timer interrupt directly to a specific handler since the timer interrupt is the only event that will be signaled on PIL 14. The irq_worklist is now in the per-cpu trap_block[]. Signed-off-by: David S.
