From: Aaron Tomlin <atomlin@redhat.com>
The khungtaskd thread limits how many hung task warnings it displays at a time, when a timeout occurs. This patch allows that limit to be set to "unlimited", by setting hung_task_warnings to -1, which will cause khungtaskd to display information about all hung tasks.
While ULONG_MAX is practically "inf", this patch takes it one step further. Note: The maximum is now 2^31-1 (INT_MAX) which should hopefully be sufficient.
Rebased against v3.13-rc8.
