| |
Hi,
Eiichi-san re-discovered the bug earlier found by He Zhe which we've failed to fix due to getting distracted by discussing how to untangle entry_64.S.
These 3 patches are basically a completion of the initial approach I suggested in that earlier thread:
https://lkml.kernel.org/r/20190320221534.165ab87b@oasis.local.home
Since v1:
- idtentry_part 'cleanup' - extra sanity check and comment - read_cr2=1 for do_double_fault - #BP vs IST cleanup - IDTENTRYx() C wrapper
The thing boots on x86_64 with lockdep on, survives function-trace, selftests/x86 and perf-test.
