[PATCH 5/5] bugs/core: Do not print CPU and PID values in__warn() output

[Ingo Molnar <mingo@kernel.org>]

For most warnings it's repeated anyway a few lines later, as
part of the register dump:

  WARNING: CPU: 0 PID: 0 at kernel/sched/core.c:8511 sched_init+0x20/0x410
           ^^^^^^^^^^^^^
  Modules linked in:
  CPU: 0 UID: 0 PID: 0 Comm: swapper Not tainted 6.14.0-01616-g94d7af2844aa #4 PREEMPT(undef)
  ^^^^^^^^^^^^^^^^^^

In fact the later dump is richer, as it includes the 'comm' line as well.

As a side effect, this makes some space for the 'file' field to be augmented
with extra information (the condition string in particular).
