From 8a177c4f17c691c2c9a08a54709d37c6db481a0b Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 16 Sep 2007 14:45:06 -0700 Subject: [SPARC64]: Warn user if cpu is ignored. When NR_CPUS is smaller than the cpu probed, let the user know that the cpu won't be used. Suggested by Al Viro. Signed-off-by: David S.
