| 2020-06-11 | x86/entry: Convert reschedule interrupt to IDTENTRY_SYSVEC_SIMPLE | Thomas Gleixner | 1 | -4/+0 | |
| The scheduler IPI does not need the full interrupt entry handling logic when the entry is from kernel mode. Use IDTENTRY_SYSVEC_SIMPLE and spare all the overhead.

| 2017-08-29 | x86/tracing: Disentangle pagefault and resched IPI tracing key | Thomas Gleixner | 1 | -7/+8 | |
| The pagefault and the resched IPI handler are the only ones where it is worth to optimize the code further in case tracepoints are disabled. But it makes no sense to have a single static key for both. Seperate the static keys so the facilities are handled seperately.

| 2017-08-29 | x86/tracing: Introduce a static key for exception tracing | Thomas Gleixner | 1 | -0/+15 | |
| Switching the IDT just for avoiding tracepoints creates a completely impenetrable macro/inline/ifdef mess. There is no point in avoiding tracepoints for most of the traps/exceptions. For the more expensive tracepoints, like pagefaults, this can be handled with an explicit static key. Preparatory patch to remove the tracing IDT.
