Message-Id: <E1ICNRo-0000lx-G2@ZenIV.linux.org.uk>
Date: Sat, 21 Jul 2007 23:29:12 +0100
From: Al Viro <viro@....linux.org.uk>
To: torvalds@...ux-foundation.org
Cc: linux-arch@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 3/3] take declarations of enable_irq() et.al. to linux/interrupt.h
Now that the last inlined instances are gone, all that is left to do
is turning disable_irq_nosync on arm26 and m68k from defines to aliases
and we are all set - we can make these externs in linux/interrupt.h
uncoditional and kill remaining instances in asm/irq.h
Signed-off-by: Al Viro <viro@...iv.linux.org.uk>
