[PATCH 0/2] Add debugfs file to dump tlb inval stats

[Nirmoy Das <nirmoy.das@intel.com>]

TLB inval stats should be useful for IGT tests as requested 
by Sai.

With this series the output looks like: 

sudo cat  /sys/kernel/debug/dri/0/gt0/tlb_stats; sudo cat  /sys/kernel/debug/dri/0/gt1/tlb_stats
GT0, TLB Requests sent: 321, received: 321
GT1, TLB Requests sent: 212, received: 212
