x86/debug: Fix the printk() debug output of signal_fault(), do_trap() and do_general_protection()
Since commit:
4bcc595ccd80 "printk: reinstate KERN_CONT for printing"
... the debug output of signal_fault(), do_trap() and do_general_protection()
looks garbled, e.g.:
traps: conftest[9335] trap invalid opcode ip:400428 sp:7ffeaba1b0d8 error:0
in conftest[400000+1000]
(note the unintended line break.)
Fix the bug by adding KERN_CONTs.
