Subject: [PATCH 06/14] bugs/powerpc: Concatenate 'cond_str' with '__FILE__' in BUG_ENTRY(), to extend WARN_ON/BUG_ON output

Extend WARN_ON and BUG_ON style output from:

  WARNING: CPU: 0 PID: 0 at kernel/sched/core.c:8511 sched_init+0x20/0x410

to:

  WARNING: CPU: 0 PID: 0 at [idx < 0 && ptr] kernel/sched/core.c:8511 sched_init+0x20/0x410

Note that the output will be further reorganized later in this series.
