[0/3] kernel/pid: Remove default pid_max value

Message

TL;DR excerpt from commit 02/03:

	The kernel provides mechanisms, while it should not imply policies --
	default pid_max seems to be an example of the policy that does not fit
	all. At the same time pid_max must have some value assigned, so use the
	end of the allowed range -- pid_max_max.

More details are in that commit's message. The other two commits are
related preparation and less related refresh in code that somewhat
references pid_max.

Michal Koutný (3):
  tracing: Remove dependency of saved_cmdlines_buffer on PID_MAX_DEFAULT
  kernel/pid: Remove default pid_max value
  tracing: Compare pid_max against pid_list capacity
