Subject[PATCH 0/2] x86/context-tracking: Remove last remaining calls to exception_enter/exception_exit()
Date
Thanks to the cleanups from Andy Lutomirski over the years, those calls
can now be removed. This will allow for nice things in the future for
x86 support on full nohz:

* Remove TIF_NOHZ and use a per-cpu switch to enable, disable context
tracking.

* Avoid context tracking on housekeepers.

* Dynamically enable/disable context tracking on CPU on runtime and
therefore allow runtime enable/disable of nohz_full

* Make nohz_full a property of cpuset.

do_page_fault()
x86/context-tracking: Remove exception_enter/exit() from
KVM_PV_REASON_PAGE_NOT_PRESENT async page fault
