[PATCH] oprofile: Add support for Intel Xeon Phi (Knights Landing)

[Michael P. <mp...@re...>]

Hi,

attached patch for Intel Xeon Phi (Knights Landing/Knights Mill) oprofile
support. 

The events/umasks configuration has been taken from Intel Xeon Phi Processor
Performance Monitoring Reference Manual, volume 2. All the events were tested
on a Knights Mill machine.

Cheers,
Michael
