[PATCH 0/2] s390x: pv: Fixes and improvements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Using the destroy call instead of the export on a VM shutdown, we can
clear out a protected guest much faster.

The 3f exception can in fact be triggered by userspace and therefore
should not panic the whole system, but send a SIGSEGV to the culprit
process.

  s390x: uv: Add destroy page call
  s390x: Add 3f program exception handler
