[PATCH] Do a single one-line printk in bad_page_fault()
bad_page_fault() prints a message telling the user what type of bad fault we took. The first line of this message is currently implemented as two separate printks. This has the unfortunate effect that if several cpus simultaneously take a bad fault, the first and second parts of the printk get jumbled up, which looks dodge and is hard to read. So do a single one-line printk for each fault type. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
