[PATCH 0/1] powerpc: Fix kuap warnings

[Shrikanth Hegde]

Recently stumbled upon these kuap warnings. This happens with
preempt=full/lazy kernel with function tracing enabled. What irked
me was kernel compilation was getting failed when i had tracing 
enabled. It doesn't fail everytime. While running stress-ng memory class
it threw same warnings. So that helped to narrow it down.
 
So one possible way is to disable tracing for these enter/exit
vmx_usercopy. That seems to fix the bug/warnings. But that will make
them as non trace-able. If there is a better way to fix these warning while
keeping them as trace-able, please let me know. 

Anyone with insights on amr, vmx and tracing, please advise.
