X-Git-Tag: omap-for-v4.2/o2_dc~147^2^2~2

context_tracking: Run vtime_user_enter/exit only when state == CONTEXT_USER

Only run vtime_user_enter, vtime_user_exit, and the user enter & exit
trace points when we are entering or exiting user state, respectively.

The KVM code in guest_enter and guest_exit already take care of calling
vtime_guest_enter and vtime_guest_exit, respectively.

The RCU code only distinguishes between "idle" and "not idle or kernel".
There should be no need to add an additional (unused) state there.
