FPII-2530 : Information disclosure vulnerability in Qualcomm components CVE-2016-6748 A-30076504

Hide kernel pointers from unprivileged ussers by using %pK format- specifier instead of %p. 
This respects the kptr_restrict sysctl setting which is by default on. 
So by default %pK will print zeroes as address. echo 1 to kptr_restrict to print proper kernel addresses.
