Thus, it can continue parsing its own command-line options while ignoring parameters that are relevant only to specific implementations of the hardlockup detector. Such implementations may use an early_param to parse their own options. Cc: Andi Kleen Cc: Nicholas Piggin Cc: Stephane Eranian Cc: "Ravi V.
