So, here is a hopefully improved version with the following changes:
* No more late wake up debugging, objtool should debug that later with noinstr code calling into the scheduler (Peter suggestion)
* Dropped the double rdp fetch patch, just keep the fix part for now
* Properly protect irq work call from rcu_user_enter() inside instrumention_begin()
* Handle CONFIG_KVM_XFER_TO_GUEST_WORK (as per Peter suggestion)
