Subject: [PATCH] MIPS: Fix printk continuations in cpu-bugs64.c
Date: Tue, 3 Jan 2017 14:51:20 +0000 [thread overview]
Message-ID: <20170103145120.14879-1-james.hogan@imgtec.com> (raw)
64-bit pre-r6 kernels output the following broken printk continuation
lines during boot:
Checking for the multiply/shift bug...
no.
Checking for the daddiu bug...
no.
Checking for the daddi bug...
no.
Fix the printk continuations in cpu-bugs64.c to use pr_cont to restore
the correct output:
Checking for the multiply/shift bug... no.
Checking for the daddiu bug... no.
Checking for the daddi bug... no.
