From e54f8548ff5285f57125c08d8092eec38dd05e0d Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 28 Jan 2011 22:08:21 +0000 Subject: sparc32,sun4d: irq, smp files cleanup - drop filename in file header - drop unused includes - add description of sun4d interrupts (from davem) - add KERN_* to printk - fix spaces => tabs - add spaces after reserved words - fix indent of a whole code block in smp4d_boot_one_cpu() Note: two printk() was updated from debug to KERN_INFO in this code block - drop all externs, they are now in header files This is partly based on a patch from: David Miller Signed-off-by: Sam Ravnborg Signed-off-by: David S.
