[PATCH 5/5] x86: Support HAVE_CONTEXT_TRACKING_OFFSTACK

2020-11-17 Thread Frederic Weisbecker
A lot of ground work has been performed on x86 entry code. Fragile path between user_enter() and user_exit() have IRQs disabled. Uses of RCU and intrumentation in these fragile areas have been explicitly annotated and protected. This architecture doesn't need exception_enter()/exception_exit() any
