[PATCH] x86: Add abilty to enable/disable nmi watchdog from procfs (update)
Adds a new /proc/sys/kernel/nmi_watchdog call that will enable/disable the nmi watchdog. By entering a non-zero value here, a user can enable the nmi watchdog to monitor the online cpus in the system. By entering a zero value here, a user can disable the nmi watchdog and free up a performance counter which could then be utilized by the oprofile subsystem, otherwise oprofile may be short a counter when in use.
