Date: Wed, 27 Apr 2011 16:53:55 +0200 (CEST) Message-ID: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Return-path: Sender: linux-m68k-owner@vger.kernel.org List-Id: linux-m68k@vger.kernel.org To: Sam Creasey Cc: Linux/m68k Hi Sammy, Do you know why NR_IRQS is defined to 200 in arch/m68k/include/asm/irq.h, while arch/m68k/sun3/sun3ints.c:sun3_init_IRQ() sets up only 128 user interrupts? I would expect either NR_IRQS to be 132 (8 auto + 128 user), or sun3_init_IRQ() to set up all 192 user interrupts. Ah, commit 35bdd52d7401b1208552523d6fa28d4a37dbc74d ("m68k: Correct number of interrupts for Sun3") changed it from 192 to 128. I guess it forgot to reduce NR_IRQS? Still, why is user interrupt 127 (IRQ_USER+127) called "vec255"? That should be either interrupt 191, or "vec191"? Is that a misconversion in commit ebba61d5b05ecfda388dd4c156bafdb78d398055 ("[PATCH] m68k: convert sun3 irq code")?
