[PATCH 1/2] sched/debug: fix per-task line continuation for console

[Joe Lawrence <joe.lawrence@redhat.com>]

When the SEQ_printf() macro prints to the console, it runs a simple
printk() without KERN_CONT "continued" line printing.  The result of
this is oddly wrapped task info, for example:

  % echo t > /proc/sysrq-trigger
  % dmesg
  ...
  runnable tasks:
  ...
  [   29.608611]  I
  [   29.608613]       rcu_sched     8      3252.013846      4087   120
  [   29.608614]         0.000000        29.090111         0.000000
  [   29.608615]  0 0
  [   29.608616]  /

Modify SEQ_printf to use pr_cont() for expected one-line results:

  % echo t > /proc/sysrq-trigger
  % dmesg
  ...
  runnable tasks:
  ...
  [  106.716329]  S        cpuhp/5    37      2006.315026        14   120         0.000000         0.496893         0.000000 0 0 /
