Subject: [PATCH platform-next v4 0/2] Interrupt storm detection

This patcheset contain:
 Patch #1 Add generic interrupt storm detection mechanism
 Patch #2 Enabling interrupt storm detection for mlxreg-hotplug driver 

v0->v4

- Impletemented generic interrupt storm detection as suggested
   by Thomas Gleixner.
- Updated the mlxreg-hotplug driver to make use of generic interrupt
   storm detection.
- Modified the logic in mlxreg-hotplug driver to track per device
   interrupts for the the shared IRQ based on the call back function
   provided by generic interrupt storm detection.
- Addressed the comments pointed out by Ilpo on earlier versions.
